I purchased this Yampa to replace a worn Marmot bag.

Rating: rated 5 of 5 stars
Price Paid: $170

I purchased this Yampa to replace a worn Marmot bag. It is extremely lightweight and durable. It has been on many trips with me, it has kept me quite comfortable down to about 32F.

What I like the most is that it is not a mummy shaped bag and affords me a lot of extra leg/body room. I purchased the long size (78"?), but I probably could have sufficed with the regular 72" length (I am 6'). It added a bit of extra weight, but well worth it.

One drawback - I owned a BA 25" down insulated sleeping pad. This size bag will only fit a BA pad up to 20". thank God I purchased from a locally owned outdoors shop (Ozark Outdoors), and they gave me a great deal with a trade in.

Overall: well worth the price and outperforms many of the bags that are easily twice the price.

The Big Agnes System is different than the traditional sleeping bag on top of a sleeping pad. With Big Agnes, the pad slides into an integrated sleeve on the bottom of the bag, and the top two-thirds of the bag is insulated in the traditional style. We el

The Big Agnes Yampa Sleeping Bag offers comfort value and versatility in a very light weight bag. At 1lb 13oz the Yampa packs down to the size of a cantaloupe but is as comfortable and roomy as your own bed. Combine the Big Agnes Yampa with the Big Agnes Air Core pad and you'll have an ultra-light sleeping bag and pad combo. We recommend the Big Agnes Air Core Rectangular Pad with the Big Agnes Yampa Sleeping Bag.

The rectangular-shaped Big Agnes Yampa 40-Degree Down Sleeping Bag has a large 70in (regular size) shoulder girth, ideal for summer camping when you don't want a tight mummy bag. The Yampa sleeping bag is stuffed with 650-fill goose down and weighs less than two pounds (regular) thanks to its ingenious design: Only the top and sides of the bag are insulated. Under you, where insulation would be compressed and useless, is a rectangular sleeping-pad sleeve that holds your pad in place, so you'll never roll off it while you're sleeping. *Compatible with 20in-wide Big Agnes rectangular pads.

Summer adventures or travel in warm climates call for the Yampa, a comfortable down-filled sleeping bag from Big Agnes. Sleeping bag has no underside insulation; in its place, a sleeve holds the Big Agnes REM Air Core Pad or any 20 in. wide pad, sold separately. Lightweight 40° modified mummy design features 650-fill-power goose down insulation—warm, lightweight and compressible. Nylon ripstop shell with a Durable Water Repellent finish sheds water; breathable nylon lining is soft against the skin. Built-in pillow sleeve allows you to stuff a jacket or a backcountry pillow inside and keeps it in place all night long. Features a wo-way, full-length, locking zipper with big, easy-to-grab zipper pull. Fabric stiffeners along both sides of the zipper prevent zipper snags. Bag will zip to another Classic Series bag if they zip along opposite sides. Includes nylon stuff sack and cotton storage bag.
