Modular Sleep System Bivy
Three-in-one is triple the fun.
A military-issue bivy with two high-quality sleeping bags all for the price of a single top-shelf bag? Sounds like the Sierra Designs Modular Sleep System Bivy has it all figured out. It's obviously a steal, starting with the waterproof Gore-Tex bivy, which features a digi camo pattern, fully taped seams, and an integrated Delrin pole to keep the fabric away from your face. There are multiple zippers, which allow for easy entry and egress, along with plenty of ventilation options. All the features are designed to be operated with gloves (the bivy's designed to be used with boots, too), so you can be ready to go at a moment's notice. Additionally, the zippers are backed up with hook-and-loop closures to provide backup in case of zipper failure.
It's hard to believe, but the Modular Sleep System includes two—count 'em—high-quality sleeping bags, too. The Delta is rated to 30 degrees, while the Gamma will keep you warm all the way down to zero, giving you 12 month protection from all but the worst elements. Both are filled with synthetic Climashield Combat insulation, which will stay warm even if it gets a little wet, and are built from tough but light nylon ripstop fabric. Insulated draft tubes prevent cold air from sneaking in around the zippers, and an oversized footbox lets you wear your boots in the bag. Like the bivy, the sleeping bags have secondary hook-and-loop closures, along with hood and neck drawcords to help you stay warm on chilly nights when you're hunting, camping, or out on solo adventures.
