I do a river trip each year, usually for about a week. last year the most experienced of us, met us half way with his kayak and all his gear in the hatches. hammock included. it was 100 degree weather all week along the river and he was cool and comfy, up quick in the evening and packed before the rest the next morning.
this year im getting headshakes from my fellow river trippers who aren't convinced of my system - i have no worries, even if it will be the first real trip for me - trial by fire
