Fantastic harness!
Very comfortable pack; I can barely feel it on my back, even when the water bladder is full and the pack is stuffed. The pack moves well with my body, even on those strenuous cross-country skiing climbs. This is my first USWE product and the harness is so good that I'll be buying a summer running pack from USWE for sure. Worth mentioning that I'm a woman with A cups, and I'm not sure that this pack would fit a woman with D cups or bigger.
