Tyvek (New) makes a lot of noise, I tried it as a ground cover for my tent.
Tyvek is a material that is cheap, breathable, waterproof, windproof, and light weight. Trace lines on the material that will fit your size for jacket and pants. Cut out two pieces for each. Tape them together with Tyvek tape and there you are. Tents, bivy bags, jackets, rain flies, and tarps are easily made. It breathes like Gore Tex. It is more durable than Gore Tex. It is very light in weight.
Of course, it does not look all that spiffy like some people all decked out in $400.00 Gore Tex jackets riding $1500.00 touring bikes, but it does the same thing and has the same benefits to its users. One guy got a 50 foot by 9 foot roll of it for $50.00 at Craigslist. It could cost $150.00 at Home Depot or Lowe's for a 50 by 9 roll. It sells by the yard in some places. It cuts easily but is very difficult to tear. You could make a breathable waterproof lightweight tent with plenty of space with a floor for maybe $25.00-$45.00, maybe less. No sewing. Just use Tyvek tape or outdoors, doublefaced, carpet tape for the seams.
