Tyvek, a wonderful fabric made by DuPont, waterproof, windproof and easy to use as a groundsheet for your tent, under your bivy bag, as a rug on the ground, etc. Bikepackingshop supplies the original Tyvek in a soft soft structure version (not in the hard version that crackles loudly and is used in construction, among other things). Tyvek 1442R is super light and weighs only 44 grams per m² (44 gr/m2: hence the name) and is particularly suitable for use in all kinds of lightweight applications. You can use them as bivouac bags, tent poles or peg bags, as long as you don’t put too much mechanical strain on the fabric (you can even make very nice kites from them, if you want).
Tyvek, the best ultralight groundsheet for your UL tent, sleeping pad or bivy
No more expensive branded groundsheets needed, you can easily make your own custom-made groundsheet from Tyvek. Super light, lasts a very long time (our current Tyvek groundsheet has lasted at least 4 years and is really abused) Tyvek can easily be cut to measure, this soft structure does not fray or “raffle” and doesnt need any form of edge binding. You can use ordinary sharp scissors to cut the fabric to size and you can also stitch it together (with a wide stitching seam) or glue it. Also ideal in a small pieces as an organiser (so you don’t loose your gear) or underlay for your backpack, As a sitpad we recommend the hard structure version. Good to know, the 1442R Tyvek (formerly 1443R) is the soft version and therefore does not crackle like the old-fashioned construction film Tyvek. This fabric is much easier to roll up and fold than the stiff version.
Tyvek is a 100% synthetic material made from high-density non-woven polyethylene fibers. Lightweight, durable and breathable yet resistant to water, abrasion, bacterial penetration and abrasion
