Great travel bag, okay beer cooler.I own the 60 L bag. It is my go to travel bag. It has hauled gear to the crag, to resorts, and to biostations. I will sweatr by this bag till the end of time. Though it is water resistant and tough, it will keep moisture in the bag if there is any previously present. Again this bag is not water proof, the zippers will let in some moisture if you are standing in a torrential down poor or submerge the bag. So make sure you stuff is dry if you don't want it to stay wet.
Compact with convenient back pack straps and over the shoulder straps.
Will keep things dry, if the things are already dry.
Different size options
Has doubled as emergency beer cooler.
Will trap moisture if water gets in.
The side pocket has an inside opening that can become unzipped. So if you have toiletries or small things in that pocket, it can get opened and things will migrate
Not a great beer cooler.
