Increase the temperature rating of your Z Top™ sleeping bag by up to 30 degrees with the versatile Booster Quilt™ accessory. When temperatures drop, simply attach the Booster Quilt™ to your sleeping bag (sold separately) with the convenient toggle buttons. It stays in place and won’t slide off during the night. The Booster Quilt is oversized, so it will drape over the zippers and ends seams of your sleeping bag, placing insulation where it is needed most to help keep you warm and toasty. The unique design makes your bag warmer without sacrificing comfort. In mild temperatures, you many just ditch the sleeping bag, and just use the Booster Quilt. The Booster Quilt makes a great camp or car blanket. It can be placed under a sleeping bag for extra comfort. It is made with a rugged water-resistant canvas shell, and a posh 100% cotton flannel liner. The efficient Factor-4™ insulation is a hollow fiber polyester that is light, fluffy, and very warm. A handy, canvas, stuff bag is included. Patent pending.
