    Comments about Sea to Summit Ultra-Sil Day Pack:

    This is a great 'packable pack' for travel or for dayhikes / summits on backpack trips. Unless you're hauling technical mountaineering gear, this looks like a very adequate daypack to pack in your backpack, with rugged looking seams. Ideal for thruhikers. I ordered two, one for a friend, and was not disappointed when they arrived, they look very adequate and are quite lightweight.
