Why didn't I buy this sooner? Because I didn't know they had them that's why! I drink a ton of water every day - and I carry a 40 oz. Hydroflask with me everywhere I go. I do have a little holder on the Hydroflask that makes it easy to carry it around, but this is even better. Way better! I especially like that I can use this when I go hiking which I do a lot of also. I love that I can take this pouch with me and can leave my purse or pack behind for couple of hours hike. This particular pouch comes with two pockets - brilliant!!The larger pocket allows me to carry a medium size tube of sunscreen (2.9 fl.oz) and my drivers license, a debit card and/or some cash. Basically everything I need to go for a hike. Or I can carry my cell phone in the large pocket with my drivers license, debit card, cash, some band-aids and some sanitizing wipes in the small pocket.The smaller pocket is perfect for your drivers license,debit card, cash and a key or two. When I take my phone in the large pocket I still take my sunscreen - I just fill up a small container (similar to one of those hand sanitizer bottles that has a carabiner clip) and attach that to the pouch.You can carry it over your shoulder or you can carry it cross the body - either way - it's adjustable and the handle also comes off if you want it to. The whole product is very sturdy, it's made well. I've been using it for several months and haven't had any issues with it. The zippers are still working just fine, and the material is perfect.The only issue I had was when I first bought it I wasn't sure that my 40 oz jug was going to actually fit. It was a bit difficult to get the jug into the pouch... after a bit of a struggle I was finally able to get it in and I haven't had any more issues since. I take it in and out of the pouch fairly often.I wish it came in different colors, but that's a trivial complaint. I couldn't tell you if this would keep your beverage any colder - my hydroflask does that on it's own... but I imagine it might help some.This was a great buy, it would make a great gift for someone who either does a lot of walking or hiking and drinks a LOT of water.
