I've just bought the new F-Form back Hot Rock 40 in "bluebird" aka turquoise...!

Good technical backpack, broad shoulder straps, weighs in just under 1kg on my scales. Tried Osprey Mutant, Lowe Alpine Crag Attack 42 and Peak Attack, Berghaus Arrete. Wanted something sub 1kg and 40 litres. Only the Berghaus and the KArrimor had wide enough straps to not dig into my neck. The Karrimor Hot Rock seemed better designed - neater less flappy strapping - less likely to thwack you in the eye in the wind, or to snag on the rock.
NB The previous non F-Form model is still available, slightly lighter, with a different back system.
