hilleberg shows us a solo tent at 2 and 14.. that's under 3 pounds (sorta ..), and the poor thing has 2 layers, one big honk'n pole plus 4 little ones in the corners. if it was a normal 2 hoop tent, it would prob come out a few ounces lighter and be much better looking.
it would have to be a very VERY trick single wall tent to be as comfortable over a long grind as a double wall. that space between the fly and body really gives a sweet buffer of protection from the elements.
if there was a lighter tent that looked as flexible, i'd be on it in a heartbeat, but for now, my next toy is a hilleberg.
peter has a paclite gen 1 parka and if he puts it on even in the summer, the world seems a colder place. it's not very friendly, but it is hella durable and it's paid for itself many times over. that being as it is, my 2 layer consumer grade goretex parka is always the choice if i grabbing one out of the closet. methinks single wall tech still has some ways to go.
