Would this work in cold weather for activities like snowboarding or skiing?
Can you use this to go to music festivals or is it too bulky? Are you guys going to make a smaller condensed version?
Is there room for one or two extra water bottles to fit? I always like to bring extra water just in case.
How is this for someone who runs half and full marathons? Is it bouncy at all? How is the mouth piece? Is it easy and comfortable to get to the mouthpiece while running and put it back out of the way?Is it easy to quickly grab a snack w/o taking off pack?
I understand the concept of this, but how do you clean the 2L container inside the backpack, is it removable? Seems to me that like all water bottles I’ve had, they get that black funk on the lids/rims, that make it hard to clean, end up in the garbage.
