As fall rolls around, things can get pretty chilly where we live (upper midwest). This gear makes a great stuff sack for blankets. After we get covered up in the blanket, we place the hot pocket under it and stay pretty toasty. I thought the price was a bit steep, but it's quickly proven its utility. So much that it's one of the first things I look for when I'm packing a bag for an outdoor event in the fall/winter. We've had outdoor electric blanket in the past, but they always seemed not worth the bother (for one reason or another). The multi use versatility of this gear tips the scales for me. An added bonus is that we never loose the stuff sack for the blanket anymore and usually have enough charge left in the battery to give our phone a quick charge, if needed.
