Rated 4 out of 5 by from UPgrade toTrailmix PLUS for size - but no key clip After using the smaller Trailmix (having 3) for years that I loved because this waistband stays put! - minimal slippage (except on slick tights). The PLUS pocket will fit most larger new phones (up to 5.75x3.75"). The only downfall is that they removed the key hook from the inner velcro pouch I always secured my key with. Worried that when retrieving items from the pouch behind you, without sight it could fall out. I'd hate to arrive at the finish line with my key somewhere on the trail. Will be using a safety pin. Will trial with full pockets soon hoping it won't bounce with having more weight than I am used to. Very nice when you just don't want a backpack style hydration system and the water can be distributed on both sides of the body. And the insulated bottles seem good!

Rated 5 out of 5 by from Doesn't budge Love this pack! I've run with different waistpacks before but they always bounce around, which drives me a little nuts. I recently took this on a long run and 1) it stored my phone (iphone 6-sized), a small snack, and enough water to get me through (the insulation on the bottles is a definite plus!) and 2) it didn't bounce around or budge at all.

Rated 4 out of 5 by from Great hydration pack!! I wish it had larger pouch for the phone. I used it for my very first marathon and it worked out well. It fits snugly. I didn't even know that it was there while I ran 26.2 miles. Bottles are little small. It only fit one bottle of 16.9oz (8.45oz per bottle). You may runout of water if you are a heavy drinker during your workouts. For me the bottles were just enough to get me to water station throughout the marathon. I love the fuel bungee on the side. It kept my gel packs snug and secure. Overall it's a great product.

Rated 1 out of 5 by from Bad tasting water The insulated bottles change the taste of water, it tastes odd and is concerning. There are several reviews out to verify this is not an isolated experience. I like the belt so was hoping to simply replace the bottle. Nathan's customer service has been very difficult to work with in resolving this. It has changed my view of the Nathan company.

Can you use regular water bottles in this pack, or only the specially-shaped ones that come with it?

Asked by: goldlyn
It is possible to use regular water bottles in the pack, however they will not be as secure.
