Love this backpack already! Used it for the first time in anger the other day for a hike in the Brecon Beacons. I carried a waterproof jacket, fleece, beanie hat, lunch, Sigg water bottle plus small items including mini first aid kit, sun cream, wallet, phone, keys, knife, pen, map, paperback. And I still had a bit of room! Feels snug and secure especially when waist and chest straps are used. I did a bit of low end scrambling and it remained tight to my body. Bombproof material and straps are well made too. The top loading, full zip access is really useful and the bag stands up instead of flopping to the floor. It has two grab handles but I'd personally do away with the front one. I would highly recommend this bag to walkers, climbers or just for the daily commute.
