Nathan Peak Insulated Waist Pack

I love this insulated waist pack. It does not bounce when I walk (6-13 miles), keeps the water cold enough, and has a good capacity. The zippered pouch is not really big enough for an iphone 6 Plus, as the description says, unless you push against the fabric to stretch it as you insert the phone. But I put my 6 Plus in a SPI belt, so it's not an issue for me. The belt is sturdy enough for me to clip a couple of blinking lights on it for predawn outings. The small bungee on the right-hand side is handy for securing one of the lights. The bungee that's next to the top of the bottle does a good job of keeping the bottle in place when carrying the belt around.

I have been using hydration systems for a a few months now. I started out with CamelBak systems a few years ago mostly for cycling and hiking. They are great but big, heavy and result in a big heat load because it blocks a large area of your back.This year I decided to do a marathon and a backpack was overkill. I needed a compact hydration solution with a pouch for fuel (i.e., gels) and my phone.This belt is the best hydration system I have used yet.PROs- It does not feel like it has a heat load like a camelbak that blocks air flow over your back.- The water bottle does NOT bounce, even running fast.- the elastic band to hold the bottle in place does its job, and I can attach and remove it behind my back easily.- The pocket fits a few snacks and my iphone 5s and a credit card.- the water bottle says cold for ~ 1 hours (started with as much ice as it could hold), and is cool after ~ 1.5 hours (not bad for days when it was 90 °F outside)-The bottle cap is always closed - you have to squeeze the bottle to push water out, this means it doesn't drip everywhere or leak.-the bottle has been easy to wash and clean so far-keeping the phone in the pocket is so much better than an arm band mountCONs- I wish the bottle volume was a little larger, but then weight and size would be an issue, so I guess it is about rightNotes: another review indicated their phone was always dry when in the pocket. There is just a mesh backing between the pocket and you, if you sweat, it will get into the pocket. My phone got damp after some long marathon training runs (~2-3 hour runs in summer heat), I tend to keep the phone in a sandwich bag now to keep it dry.

I only use this on my long runs as I really hate having anything on my waist when I run. This is pretty comfortable. I am 5' 4" and 120 lbs. If I wear this at my waist, which is where it feels the most secure, the lower edge of the bottle digs into my back. It's not enough to hurt but it's annoying. If I were to leave it there for for longer than an hour it would likely start to hurt or rub. Instead, I have to wear it lower, on my hips. There is a little bounce if I wear it lower but that improves as I drink more water throughout the run. The little pocket is nice. I can fit a good size OC spray canister in there. My phone gets tucked in between my jog bras so i don't need to fit it into the pocket. The adjustment straps are long so they would accommodate a variety of waist sizes. They have little velcro straps so you can securely tuck away the long ends. There is a gear strap but I haven't tried it out yet. The color (light teal) is cute. The insulation works - I get incredibly sweaty on my runs and I bought the insulated product so my body temp wouldn't heat up my water. Overall I like the bag, it serves its function well. I may try some sewing to change the angle at which the bottle sits to better tailor it to my body. Oh yes, about the bottle smell so many have complained about. Yes, it smells a little. Like plastic. Which is what it is made of. It's no big thing and the odor fades with use. I only run one long run per week so I only use this belt that often. I add a flavored powder to my water and I don't notice any strange taste or odor while drinking from the bottle out on my runs. This is a good product and I have no qualms recommending it. It is probably perfect for people longer waisted than me.

Took this for a 15 mile break in. By packing it full of ice it does stay pretty cold for 2 hours. This was definitely a plus for me. The claims it won’t bounce? Not so much. I had hoped it would be less than the FlipBelt I was using before, but was disappointed. The win for Nathan was the ease of use of the holster and the cold lasting longer. I don’t mind the belt as much as other have complained about, and used the Velcro tabs to keep the belt from slipping. As far as the pouch, it holds my iPhone 10XSmax with a key fob, AirPod case and a gel without issue. Over all good product, but belt and bouncing kept it from higher rating...

The belt is quite comfortable and fits well once you adjust the strap to your size. My waist is 26.5" so, it didn't require much adjustment since the strap comes at it's smallest and you roll out more strap on the sides until you achieve the proper fit.The pocket easily fits my phone in it's silicone case, a travel pack of tissues, and a lip balm. However, my phone is on the smaller side. The pocket probably won't fit one of the really big phones like an iPhone XS or some of the massive Galaxies.Since I'm petite, I was concerned that the 18oz bottle might be too big or awkward but it isn't. Between the bottle's flat shape, the heavily padded pocket it sits in, and the anchoring cord, it's comfortable and doesn't move around. There's sloshing when you move but that's what water does no matter what vessel it's in. The bottle is quite easy to take out and put back while moving. The bottle nozzle pulls right up for a quick squeeze and goes right back down.There's a large gray plastic marketing tag on one end of the strap. It's awkward, unnecessary, and seems like it's seemless and undetachable but there is a split in the middle of the tag under the strap. You just need to pull the tag to one side and wiggle the strap out of the loop to take it off. It's hard to describe but once you try it, it makes sense.
