The Bos Sheet is made out of the same non-tear woven polyethelene as the Bosbags. It measures 84" x 84" and had corner handles to make moving grass clippings, hedge trimmings, leaves and weeds easy. (doesn't that sound like fun?) It's also a good groundsheet for picnics and camping trips. It's washable and folds away to a small, flat rectangle 10" by 15". WAY better than a tarp and a lot easier to carry. Waterproof and made in UK Dimensions: 5' x 5' Weight: 14oz.
