During modern deer my dad brother in law and myself planned a pack in wilderness trip. We wanted to cut weight so we shared a 2 man tent ( it was tight but being in the middle I was sleeping on 3 mattresses and warm). We decided we needed a tarp and after trying to clear a purchase with the wife I settled on a 9'x9' tyvek tarp with strapping tape as loops. It held together very well in mild weather but I havent tried it in rain or snow yet...
I have one hole to fix because Dad decided to take trekking poles with him opening day and held up the tarp with a stick.
It gave us lots of room to store gear and cook.
Its been done before but it may perk some peoples interest.
Weighs in about 1.2 lbs.
