Reviewed by Stuart Reid - 15th Apr, 2017Everything you need in 20L day sack.I couldn't ask for more from a little day bag. Having 20L of volume is was more than enough to carry my kit and some food and a drink. This bag has mesh four way stretch pockets for easy access for water bottles on either side and is also hydration tank compatible too. a front pocket to stash you map or GPS unit is really helpful to have it all close to hand. I like the fact that it is walking pole compatible too if you are on a longer day walk or getting some height and feel poles might be needed. A highly breathable back system with a waist and chest strap & rain cover. Perfection in 20L.
