Ultralight tents donâ€™t have to lighten your wallet.Save a bundle of cash by making one from Tyvek. The breathable, water-resistant material, a favorite of home contractors, weighs less than two ounces and costs about $2 per square yard. Hereâ€™s how to fashion a featherweight bivouac from the stuff.Â
MATERIALS & TOOLS
Two 6-foot by 9-foot sheets of Tyvek HomeWrap, hammer, Â½-inch grommet kit, 8 lengthsÂ of 12-foot-long parachute cord (or thin rope)
1) Lay one Tyvek sheet on the ground, and fold over three inches of each edge.
2) Hammer a grommet into each corner and the center of each folded edge.
3) Tie a parachute cord to each grommet.
4) Push a tall stick into the center grommet of one short side. Stake or tie the other end.Â
5)Â Fasten the ends of the parachute cords to trees, rocks, or stakes to pull the Tyvek taut.
6) Use the other sheet as a ground cloth, roll out a sleeping bag, and catch some zâ€™s.
Approximate time:Â 1 hour
Cost:Â About $25
