Ultra i-35™ Description

Protect your device and your valuables with the Ultra i-35, carry credit cards, ID, cash, keys, and anything else you might need, hands-free.

As you take on the world, don’t get caught with nowhere to store your stuff. This three-compartment armband moves with you—cushioned with form-fitting memory foam—so it won’t budge, even during the toughest workouts.

NEW! 100% Reflective option offers up to 500 ft.* of visibility for added safety in dim lighting conditions.

*Reflectiveness depends on the brightness and angle of the light source, darkness of surroundings and placement of product.

Bring it all, or Travel Light

One size does not fit all. That holds true for mobile devices, as well as our customers’ individual needs. Some like to workout with only the bare essentials, and keep their armband as light and slim as possible. Others need to bring keys, cash, energy gels, diabetic supplies and an ID. We’ve got you covered either way.

IPX4 Weather & Sweat Proof

Laboratory tests were performed by National Technical Systems (NTS) laboratories where it was determined that Armpocket armbands achieved an exceptional water-ingress rating of IPX-4: weather, sweat, mud, and splash proof certification.

No more plastic baggies for your phone.  

Sweat, rain, snow, sleet and sprinklers - Armpocket has you covered.

Shock & Drop Proof

Armpocket armbands were awarded MIL-STD-810G certification rating by NTS Laboratories - the most commonly used utilized standard for environmental testing for military products. Our fitness armbands exceeded the rigorous criteria for protection against damage, life-cycle wear, ruggedness, and durability.

Rock those double black diamond trails with confidence. 

Armpocket has you covered.


If you enjoy working out surrounded by mother nature, you care about your impact on the environment. And so do we. That's why every Armpocket armband features fabric made from recycled plastic (PET) fibers, as well as natural bamboo rayon, which is moisture-wicking and resilient to bacteria, mold and mildew.

    Excellent fit and utility!

  • Cameron G 2017-01-16

    Sturdy zip, Spacious Interior, Phone sits nicely, Very Comfortable Velcro / Straps / Memory Foam padding.

    I use my iPhone 6 in a medium case (not bulky, but still edges) and it works great (interior elastic keeps it pressed against screen cover) + still fits key with key ring.

    Fantastic product!

  • Mark 2016-12-14

    This is a runners best friend! It's tough, comfortable and lots of space.

  • Barb Bovberg 2016-12-04

    I love my new ultra i-35. This is my third Armpocket (I've needed new ones as I've upgraded to a bigger phone). It's the best armband hands down. I use it when I run or walk and on bike rides. It safely holds my phone and I can store my ID, a credit card, and my keys. It's an essential workout item for me. Fantastic quality. Thank you!

  • Michael Garcia 2016-11-18

    Over the past few months, I began training for my first 10K. Along the way I tried many different armbands and running belts, but none of them have been as effective as the Armpocket. The zippered enclosure makes it very easy to take my device in and out, the interior lining truly does block out sweat, dirt and dust and the Velcro strap kept everything nice and tight during training. It was really nice to be able to focus solely on my running during the race, and the Armpocket allowed me to do that! My Ultra i-35 will definitely be a central component of my training gear from here on out. Thanks Armpocket!

  • William M 2016-11-18

    After trying many different cheap Chinese armbands I'm glad I finally invested in a high quality one like this. It's very waterproof, closes reliably, and the Velcro on the armband is solid. Seems like I'll get many times the use out of it compared to the cheap ones.

  • Scott 2016-11-18

    For me this is hands down the best armband out there. I have an older version but needed a new one for my new phone. Armpocket armbands just keep getting better. Quality is great, lots of fun colors to choose from. Phone does not jiggle or slide down. Strap on and run. Love it!

  • Amber 2016-11-18

    Awesome product. It does the job it is it supposed to do.

  • Jennifer Kyle 2016-11-16

    I accidentally shipped my armband to the wrong location, I contacted Armpocket customer service and explained my situation (I needed it in time for my race). Armpocket overnighted me a new one to have in time for my race. I was able use my new Armpocket for the very first time during my marathon. I have used Armpocket for the past 2 years and have not experienced any chafing or discomfort.

  • Linda H 2016-11-14

    I use my ArmPocket any time I need my hands free, whether it be working around my acreage, where it allows me to keep my phone handy or at places like amusement parks, where I have everything I need (phone, money/credit card and keys) right with me. It makes it so much easier to get on and off the rides and keep track of my things at the same time. Very well made product and comfortable to wear. Make great gifts!

  • Alicia 2016-11-14

    Love this! I had a similar band, but it wore out after just one month. Got the armpocket as a gift and loved it so much that I bought one for my hubby, too! I'm not a runner, but I have really loved having it for skiing AND fishing trips. Great quality, worth the price, definitely recommend.

  • MAC 2016-11-11

    I have used my Armpocket for over 6 months and very impressed with the quality of this armband. I use it at the gym, training runs, and Spartan races. When it gets dirty I toss it in the washer and it's as good as new. Totally recommend this product!

  • Mark 2016-11-11

    As a pilot for a major airline, I'm required to display my ID, go through security screening, and perform aircraft exterior "walk-around" inspections before every flight. My Armpocket is a critical piece of my flight gear. Often on the ramp in high winds, torrential down-pours, and blizzard conditions -- my ID, phone, and keys are safe in my Armpocket's weather-proof storage compartment. With its memory foam padding, I don't even need a protective case-- which along with it's soft, vented strap, allows me to comfortably wear it all day (and night.) At night, this is critical as my "office" is completely dark and very easy to lose things which has happened before I started religiously wearing my Armpocket. I don't fly without it! Plus it's great for exercising, yard work, and anytime I need my phone with me. I highly recommend it-- great quality and well worth the price!

  • Dale Juntunen 2016-11-11

    Easy to insert phone and very comfortable while running.

  • Joel V 2016-11-09

    I am a firefighter and I have the Ultra i-35 yellow. It fits my iphone 6 with case and has high visibility for safety.

  • RunGirl 2016-11-09

    Armpocket is by far the BEST armband I have ever tried. I have tried a ton of them, and I nearly gave up on the entire armband concept before I found Armpocket. So glad I did, a few extra dollars than some of the others but beyond worth it! Worth every penny.

  • Sealsle 2016-10-24

    My iPhone 6s fits nicely. I have used it for 6 months now... 4 times a week at gym... and still in great shape. I used it on the beach too -- the slots/pockets inside are great for credit cards and some cash.

    I would recommend this to a friend!

  • Trish 2016-10-24

    Love it, great while out walking around and listening to music

    I would recommend this to a friend!

  • Happy Shopper 2016-10-24

    Daughter uses during cross country practice and it seems to work great.

    I would recommend this to a friend!

  • Kaye Eccles 2016-06-04

    Quality product with outstanding customer service.I use my i-35 for running...it stays put & allows me to carry my ID,keys,tissues & money without any problems. I have washed it numerous times & it is still good as new! The generous size allows me to carry my S6 in my Otterbox defender case without having to remove my case each time. Definitely the best of this type product on the market.Thanks Armpocket!!!

  • Astra V 2016-05-23

    I used a smaller armpocket for the past two years and have LOVED IT! They are comfortable and keep the items inside dry no matter how sweaty I've been (summers in Florida get HOT). I recently upgraded to the ultra i-35 after getting a new larger phone. It fits well and holds my phone (in a case) and a key and id/credit card perfectly. I will continue to recommend and buy your products!!

  • Bret Miller 2016-05-01

    I wanted a way to carry my phone, house key and ID while I was running. This product is exactly what I needed. It fits well and stays put while running. It's a high quality product. It's worth the money.

  • Chad Mitchell 2016-04-27

    This is a great phone case. I have used mine with a 5S and now the 6. This is the only one out there that would fit comfortably around my arm (L). I'll get another one if mine ever has a problem. I highly recommend it.

  • Hottmess 2016-04-13

    This is my second one of these. I used one on the iPhone 5S now on the 6S - its perfect. Great fit - stays clean and dry.

  • Peter W. 2016-03-18

    I ordered, it shipped, I have it, it couldn't have been smoother, THANK YOU.

  • Kelsey Overberg 2016-03-09

    Really happy with this product. It is super comfortable! It fits my iPhone 6s with or without my Otterbox Commuter case. It is easy to use the phone while it's in the Armpocket, easy to get in and out and has extra room for some cards/cash/snacks. Do be sure you check your measurements for the sizing, I assumed I'd be a small but thankfully measured before ordering and found out that I'm a medium. Sizing was accurate upon actually trying it on. The free shipping option was also incredibly, surprisingly fast! Very pleased overall with this product and service.

  • S.O 2015-07-31

    I wanted to tell the readers how nice Armpocket customer service is for taking care of my Ultra i-35 for my galaxy note when I needed help. I love the product and it does not let your phone get wet from the sweat at all and the arm band does not slip and slide like other products out there in the market. The care of this product is easy and it is also long lasting. No moisture. I highly recommend this product and I will be upgrading to the Mega i-40 soon. This product has helped me go on my long runs without worrying about carrying my phone like I used to. Thank you for excellent customer service!

  • Kaye BE 2015-05-19

    I Love my Armpocket!I have this exact color (Splash) & would not run without it. Stays put & is the most comfortable armband I have ever worn. Highly recommend it!!!

  • Roxanne Clarin 2015-04-28

    Decided to try the armpocket out since all sportbands I have tried so far has let in sweet into the case made my phone all wet.

    I was gladly surprised after I discovered I had finally found a sportband that lives up to its description.

    After 75 minutes of hard spinning the pocket was still totally dry!

    I have to say I was amazed!!!

    Never gonna change to another sportband!

    A big plus is that it's also big enough to hold the case in which I keep my medications.

    And the band don't slip down my arm when I sweet.

    Try it...NOW!

  • Roxanne C. 2015-04-21

    The ultimate sweat test ". I have tried at least 10 sport -armband in chase of a brand that would not kill my mobile phone. Most of the armbands I have tried have been made by neoprene. Not one of these sportbands have stayed dry. Never lasted longer than 15 minutes, after that my phone was soaking in sweat and the display covered in condensation. After reading about Armpocket in sport blogs and on the homepage I decided to try it out. And, WOW! Stayed dried for 75 minutes of mountain climbing spinning where my pulse under all this time was 75-95% of my full capacity. I checked the pocket after 30 minutes, still dry. Checked again after 60 minutes, dry. And finally after 75 minutes. STILL dry as the Nevada desert :-) . I can't believe this Armpocket is for real! The best alternative for all of us active persons who like to push our limits to the edge! Rate:10/10! The foam next to my skin perfectly stored all sweet before it could reach the phone. Never gonna use another armband! Thank you Armpocket! No condensation or sweat inside pocket.

  • Chip E. 2015-03-27

    This armband fits the iPhone 6 like a glove and is superbly well made. Top quality and it's virtually waterproof. 5 star. Would highly recommend.

  • Paul Perkins 2014-12-14

    This is the 2nd Armpocket armband I have owned. This is an ultimate product in appearance (yellow and black), construction, and fit. I use it for workouts at the gym. It does not slip from its position on the arm and remains comfortable even when exercise expands the arm muscles. My phone, a Moto X 2nd gen, has a slimpoly-carbonate protective cover (Case-Mate Naked Tough) on it and is easy to get in and out of the zippered pouch, a perfect fit in this armband. I have complete trust in this product. The Armpocket organization is customer oriented and superior in customer support.

  • James M. 2014-05-02

    I used my Armpocket during training and running of my first marathon. It was perfect to carry my phone, keys, ID and cash!!!

  • isaac saw 2013-07-03

    I tried the i-15 (as recommended on the website) for the Samsung Galaxy S4 with a thin case and yes it will "fit" if you use that term very loosely. You will have to force close the zipper around your phone. You will not have room for anything else in there including the headphone jack and you don't get access to 1/4 of your screen. BUT all is well because the i-35 is the PERFECT fit for the Samsung Galaxy S4 with a thin case on it. You also get access to the FULL screen and you have room for smaller items if you want. These are the best armbands I've seen for the larger phones if you don't own an iPhone. Very comfortable and seems to be great quality! Thanks guys for a great product!

  • Meghan Sims 2013-07-03

    I have had the I-35 for a month now and I love that I can carry my diabetic supplies with me when I run. This includes my PDM (I use the OMNI Pod system) test strips, glucose tabs, running jells and my keys. I do have to put the test strips into a small plastic baggie as a round container just doesn't quite fit. And will all that on my arm, it doesn't fall down and stays in place for my entire runs (10k) Well made product. Highly recommend it!!!

  • wendi damico 2013-07-03

    Love Armpockets period!!! But the i-35 is a perfect fit for the Galaxy S4, with or without a case. If you have a Galaxy S4,I would recommend the i-35!

    Happy running!!!
