From Ramsey Outdoor:
"The Big Bang? is an ideal winter bag for snow camping and back-country skiing. Constructed with Mountain Hardwear?s exclusive moisture shedding Condui..."

From EMS:
"Rated to -15F, this high-grade down bag offers up an expandable girth, allowing you to sleep through a much wider temperature range than previously possible. Expandable draft tube offers up to 8 inches of girth, meaning that the bag can still be comfortable when the temperature rises up to the teens. 600-fill goose down is compressible, long lasting, and has a terrific warmth-to-weight ratio. Conduit SL shell is windproof, water resistant, and highly breathable. Down-filled draft collar seals in heat below shoulders. 4-panel contoured hood seals in heat, exhausts moisture. Full-length insulated zipper gusset prevents heat loss. Multipaneled footbox for enhanced thermal performance. Snag guards prevent zipper snags."

From REI:
"Big Bang lets you buy just one sleeping bag to use for cold, demanding trips, as well as milder-weather backpacking outings. Quantum Expander allows unparalleled versatility; zip it up for a snug, more technical fit or unzip it for 8" added girth, yielding a roomier bag. Bag has been reshaped to bring the down insulation closer to the body, without being uncomfortably restrictive. Specifically, room has been added at the elbows and hips, while reducing volume around the head and from hips to knees. Conduit™ SL shell is water-resistant, windproof and extremely breathable; warm 600 fill-power goose down is lightweight and compressible. You can enjoy all the comforts and benefits of goose down, plus feel free to use this bag in wet conditions. Box baffle construction creates maximum loft with minimum weight; 5-inch baffle width keeps down from shifting and prevents cold spots. Warmth is optimized by differential cut of shell and lining, allowing the goose down adequate room to expand to its full loft. Ergonomic overfilled draft collar drapes comfortably over neck and shoulders, sealing out drafts. Multi-baffle, tailored hood has a down-filled face gasket which makes hood closure more comfortable and effective. Multi-baffle Comfort Foot Box is shaped to allow feet to rest naturally; shape preserves loft and allows down to drape closer to feet for more warmth. Two-way, locking, snag-resistant zipper sliders stay in place when venting. Comes with mesh storage sack and waterproof stuff sack."

Men's Big Bang SL
Reviewed by LARRY BURKE, Jun 02, 2007

"I have slept in over a hundred sleeping bag types, and prior to this one my favorite was the military extreme cold bag. But it weighs 11 lbs and is big, heavy and awkward to backpack with. But, warm and comfortable.
However, because I could not see what could be done to a sleeping bag to make it worth that much, I was not willing to pay $300 + for ANY sleeping bag; this was given to me as a gift."
