Gossamer Gear Polycryo Ground Cloth SPOTLITE REVIEW

Overview

For you gram wienies - yes, you! - the Gossamer Gear Polycryo Ground Cloth is the lightest ground cloth that we know of (1.3 oz / 36 g) that is tough enough for multiple trips. Half a space blanket is lighter, but one puncture and they rip apart. I've had the same Gossamer Gear Polycryo Ground Cloth out in the desert for 7 nights and the dunes for 5 nights without any damage.

 

I used the Polycryo Ground Cloth with a sleeping bag and with a quilt, without a bivy. Both bag and quilt sometimes migrated off the Ground Cloth and into the dirt. I'd like to see the Gossamer Gear Ground Cloth offered in a slightly wider version. Gossamer Gear offers a 6' x 8' ground cloth but in a heavier material (apparently wider Polycryo sheets are hard to find).

Destruction testing further confirms that the Gossamer Gear Polycryo Ground Cloth is tough and puncture resistant as claimed. I cut a couple of pieces from my used Ground Cloth and destroyed them. I ground a piece under my foot on concrete a few times - no holes. When I next ground it on tiny gravel, I produced several holes. When I pulled the edges of the Polycryo square, it did not tear immediately (unlike a space blanket).

I poked a sharp stick into the second square of Polycryo until it pierced the material. It took a little, but impressive, bit of push to force the stick to puncture the Polycryo. I pulled on the edges of the square and, not weakened by the grinding on concrete test, it took some extra effort to stretch the hole until the Polycryo tore.
