Kelty and Slumberjack put together this system as an alternative to the standard issue sleeping system. I've only used the 0ºF Gamma and Bivy bag for a few nights of single digit weather up in the Adirondacks and it held up fine. It's in excellent condition. No tears, no stains, nothing.. as pristine as a used item can be. US Elite gear sells this system for $624.75+tax+S/H (http://www.us-elitegear.com/gear/sleeping-bags-pads/kelty-varicom-complete-system-1.html) and I've seen just the bivy sack go for over $200 on ebay. I would like to sell this system for $350 Shipped OBO. SOLD xx6py6ro6xx
Here's a description of the sleeping system I found online:
The flexible VariCom System consists of five interchangeable components, including the Delta 30ºF sleeping bag, the Gamma 0ºF sleeping bag, the VariCom Bivy and two compression stuff sacks. The system offers a temperature rating between 30ºF to -30ºF and even lower temperature ratings can be achieved if the system is used in conjunction with layers of extreme cold-weather garments. Both the Delta 30ºF and Gamma 0ºF sleeping bags feature Climashield Combat insulation and double-offset, differential-cut construction, which eliminates cold spots. Each bag has a nylon, ripstop outer and interior liner for durability and compactibility. The Delta sleeping bag comes with an Enhanced Situational Awareness (ESA) hood, which provides coverage around the head, yet reduces sound-blocking fabric around the ears. This patent-pending hood maximizes awareness levels when sleeping in hostile conditions. Slumberjack offers an optional anti-microbial VariCom Bag Liner, which provides moisture management for warm nights and extra insulation for cold nights.
In addition to the sleeping bags, the VariCom System comes with the VariCom Bivy, which keeps the user dry in up to 2 inches of standing water. The bathtub-style bivy incorporates a stuffable,
patent-pending Delrin® hoop, which keeps the mesh away from the face. The VariCom Bivy measures 35 inches by 86 inches and weighs 2 pounds. In addition to the bivy there is the optional No Fly Zone, which provides light protection from flying insects. Its mesh construction provides full coverage around a sleeping bag. The complete system weighs 9 pounds 10 ounces and compresses down to 11 inches by 11 inches when fully packed.
