The harness is good enough to walk a kilometre with, which the North Face straps are not — you pay for that in weight and in a slightly less bombproof shell.

Do not buy this if: Porter-carried loads, where the harness is dead weight and something to snag.

Best overallMountain Hardwear Camp 4 Duffel 65 L
Weatherproof, takes a bus roof in rain without complaint, and 65 litres is the size that keeps you inside a porter weight limit. Take this rather than the 95 L version: the big one is a trap, because you will fill it.
