I recently ran across what purports to be a water repellant picnic blanket sized 55x44" for $25. I didn't buy it. My kits have Heatsheets 2-person blankets, which are 60x96", water proof, and presumably a lot warmer. The Matador looks like it folds down smaller and is designed to be refolded back to its small form, where I view the Heatsheets as being a reasonably robust single-use item.

Anyone familiar with the Matador, or preferably both?
