Works for small/petite people

I'm a small person (5'2" 100 lbs). It's difficult to find a waistpack that'll fit snugly to a 24" waist without acting as a corset. Good news small people of the world. The elastic band on this pack is infinitely adjustable and has just enough flex to make it comfortable without sacrificing stability. Make no mistake, it'll stay where you put it, AND you won't have to take it off if you eat a big meal.

Bought this waistpack because I needed something to carry my slim wallet, cell phone & lip balm while I was out on the town. This meant it had to fit close to my body, be invisible under a coat/jacket, secure enough to deter thieves, and comfortable to wear for extended periods of time. This waistpack fits the bill and more. I've gotten to the point where I now take it almost everywhere. I've run in it, walked, hiked, climbed and simply worn it around town on trips to the market. For what I need it to do (hold just the items I absolutely need), it does a spectacular job. I've had no problems with the zipper, but it's nice to know that if I ever do, I can just take it back to REI. The only thing I might change (or just as a small DIY project) is attaching a small string or pulley to the very small zipper.

I was worried about the pack staying in place because I was blessed with wide hips and a small waist. The pack won't stay on my hips, but it's been absolutely no problem running with it around my waist. Today, I ran 8 miles in warm weather with my inhaler, cell phone, iPod touch, and a chapstick stashed. Even with everything jammed in there, the pack didn't move one inch during my run, and I barely felt it there. I always think it would look more stylish if it would stay around my hips like a regular belt, but it rests at the small of my back and the weight virtually disappears. The three-sectioned compartment divider was a brilliant idea. I've been able to pull out my iPod mid-run without worrying that I might lose my ID or emergency (ice cream) money.

Heading out tomorrow to get new shoes, and I'm planning to pick up two water bottles to add. Will update my review once I've had a few runs with the water bottles.

Stable and functional belt

As indicated above, I am a minimalist runner and do not like to carry extra items with me. However, when training for a 50 mile race, I wanted something to carry water and items for the mid mileage runs ( 7-12 miles)!instead of a backpack with a bladder. Being a very small female, I was concerned about many of the belts I read being too large and slipping, and as the Amphipod had the best reviews, I decided to try it. I am extremely happy with the belt and it can snug up and adjust down well to feel secure around my waist. Even with two fuel bottles attached, the belt does not feel too weighty. The belt has a buckle system instead of Velcro which I like. The fuel bottles that can be purchased separately are easy to disengage / reengage and drink from. The pocket size is adequate to fit some bars and other items. Great system overall.

BEST runnig belt for iPhone +a

I've tried many running belt, Nathan, Fuelbelt, Asics...list goes on. They were okay for some IDs and gels and keys, but when it comes to a large phone like iPhone, it was no go for me as they either bounce too much for slid all over the place.

Not with the Amphipod. This thing is the beast! Pocket area is veeeeery wide, hugs the back and lock on. Also the waist belt is streachy and sticky, hence they hug my waist really well. This is EXACTLY what I've been looking for. And because they hug my waist so well, I don't notice the weight of my phone or other junk I carry. Also it's perfect for my iPhone which has huge Otterbox defender case, which most phone pouch or case are too small for.

higly recommend it. I always carry it on daily run & daily run away from home (traveling)

Can barely feel it's there

I ran a few times this winter with this waist-pack/belt/fanny-pack, when it was warmer than 40 F. I had on just running tights, a pair of shorts, and shirts, and a windbreaker or a sweatshirt. It went right over the shorts, and I barely knew it was there. It had just my phone (for weight and size comparisons, it is a Nexus 5), and cards, money, and key. In the spring, I won't have the shorts on, but I doubt I'll feel it then, given the light weight and wide and (relatively) soft belt. The pouch zipper closes over the Nexus 5 with only a little effort, and this is a big screen, so this pouch is spacious. I think the water bottles they sell for their heavier belt will work with this one too, but I haven't tried that yet.

Highly Recommend!

This came as a recommended brand by a buddy of mine who is a cyclist/triathelete.

I use mine whenever I ride my road bike. The Endurance Waistpack has 3 small pockets on the divider that can hold an ID, credit card and money. The waistpack can also hold keys, smartphone and the exterior stretch pocket can hold gel packs. The waistpack is also long enough to fit a Topeak Pocket Rocket pump!

Even when packed with a phone, keys and other ride essentials, the waistpack does not bounce around or sag due to its stretchable waist strap. Its comfortable to wear and low profile enough to be kept under a shirt or jersey.

I highly recommend this waistpack for cyclists as it keeps your keys/ID/Phone on your person.

Functional and comfortable w/out bounce

Great no bounce minimal option that will still hold a card wallet, a smart phone, and a key or three. The main zippered compartment has a divider so you can separate your keys to keep them from scratching your phone. The main pocket is easy to access if you want to start/stop your workout app. There are also two outer pockets (no zippers) to put gel packs or (unused) poop bags for your pup. It is very adjustable and you can cinch it down with the wide stretchable waist band to almost no bounce, or you can easily wear it looser for a trip to the farmer's market. Wearable around your hips or waist. Nice product!

Purchasing a backup ...

As a fat person (sorry if it offends), it stayed around my waist during my attempts at running holds MP3 player which is one of the only things that keeps me moving. A year later, it has followed my waist size as it decreases. Wicks moisture away just like it says. So much so, the salt flakes off(gross) but reflective of good workout. Drys fast. It doubles as a wallet (FL wear no pants) it looks cool. Buyin a second just in case they quit making em. Use everyday, on and off often. No signs of wear n tear. GREAT PRODUCT!

Fills the bill!

I'm a 78-year old with a history of two heart attacks and stents. I walk 5-6 days a week year-round for a target 25-30 miles through my neighborhood and the surrounding desert. Need to carry ID info, Nitrostat tablets with instructions for administering in the event of another attack, full prescription lists and doctor contacts, together with iPod Shuffle and earphones,keys,etc. After many previous makeshift attempts, this waistpack meets all my requirements -- I can even hang a water bottle on the waistpack for my longer walks. A great solution for my requirements, without becoming an awkward burden. Thanks REI/AMPHIPOD.

Perfect size and fit

This is an excellent belt to carry everything you need for running - gels, phone, key, MP3 player, etc. It stays put and doesn't weigh you down. Unfortunately, adding the Snapflasks to it is not a good idea. It unbalances the belt and causes it to shift around, and the flasks themselves are poorly designed to stay on. Horizontal configuration stays in place better than vertical but uses up a lot of space. Enjoy the belt but get a different system for carrying liquid.

Negative Reviews:

Poor;y made

Purchased to ride RAGBRAI (ride across Iowa). The zipper broke after only a few uses. REI was great to replace, but company needs to improve design by adding a stop similar to ones on coats.

I personally would not recommend this product.

Zipper broke

For carrying camera, money, energy bars while skiing. It's the perfect size and nice that it stretches, but the zipper broke after only a few uses.

Works well (but uncomfortable for me)

This carries everything I need for a walk/run (keys, phone, ID, iPod) easy with plenty of room to spare. I've had it for about two years, and it is a very secure way to carry essentials and is not very bulky. It seems well made. My caveat: I only use this in the summer (when I don't have pockets) because I find it uncomfortable. I am a normal weight with a small waist, and it rides up to the smallest part of my waist and bounces when I run and I keep having to pull it back down. I'm more comfortable wearing it around my lower abdomen above the hips, but it doesn't want to stay there. It is fine when I walk but is another story when I run.
