now i've had it a few weeks I can say definitively don't be tempted by the UD fastpack 25. just about enough space and nice enough features, doesn't bounce too much when jogging but sits horribly and impossible to get to sit on your shoulders properly with the adjustment straps it uses. weight just pulls bag down and away from your back which pulls shoulders back awkwardly. used it for 2 days on south downs loaded with 8.5kg and again for l2b only about 1/4 full and my shoulders/back were killing me after about 3 hours both times. talking to a guy with the older fastpack 20 at a checkpoint stop he had exact same issues but had paid a mate to modify it with additional straps to compensate but seems more hassle than it's worth. shame as it looked bang on the money.
Sounds pretty poor design. I like the principal but think £ better dropped on a rucksack. If get to pointy end of long trail/fell stuff then a vest would be wort it for marginal gainz...
