MIRACOL Hydration Backpack with 2L BPA-Free Bladder Lightweight Hydration Pack for Running Hiking Climbing Biking Cycling Skiing (Grey)

First off, this item was shipped extremely fast! Had it next day. Next, the size is perfect for me- I am 5', 115 lbs. I will be using this pack while snowboarding this season (2020). I have not used the bladder yet, so I can't really comment to the durability of that, but the size is the most important and can't beat $20 for a backpack plus a bladder (2L). I do love that the tube is insulated as well! Plenty of room for my necessities on the mountain (phone, ID, snacks, ...etc.). Very happy.

I use this while skiing. It's primarily a water pack but I was able to carry my vest in the outside straps and one can always place cell phone or keys etc. in the zippered pouch. I like the fact that the hose is insulated although when really cold one should drink frequently or the water in the hose will freeze. I would recommend this back pack to any of my friends.

It's great in a hot day and perfect size I am very happy with it

This product is the perfect size for me. I am 5’7”, 180lbs (for reference..size large shirts). The chest and waist straps fit well with still some portion of the strap left to adjust for a bit larger size. Super comfortable to wear while running and holds enough water. I purchased one for my father as well and the fit wasn’t quite right, he’s 5’10” and 220lbs. However, he can still use it comfortably and uses it often. I love the zippered pocket on the front, great size for my iPhone XS. The straps inside hold the bag in place so well.

I ordered three of these for my sons and I to use when hitting the bike trails. So far I’m really happy with them. There are a few very minor things that could be better, but overall it’s exactly what I was looking for. Lightweight, easy to clean, very comfortable, easy to use. The outer material that makes up the front of the pack is extremely thin so it will probably tear easily if you’re not careful. The insulation works very well, I placed a small ice pack in with the bladder at it stayed cool for the entire 3.5 hour ride on an almost 80 degree day in the sun. There is not much room for anything else once the bladder is filled but you could feasibly fit keys, a trail map, a granola bar or two, and a few small first aid supplies. But that’s about it. So it’s great for a ride or hike that will only be a few hours, and close to civilization for accessible supplies. The only truly disappointing feature on this bag is the built in emergency whistle. I like the idea, but the whistle only works on 1 out of the 3 bags we received.
