Redefine comfortable camping.

Sierra Designs started from scratch when it designed the Women's Backcountry Bed 600 Sleeping Bag so you can experience the utmost comfort at your campsite. Free from extraneous hardware like bulky zippers and drawcords, this intuitive bag features an oval-shaped opening with an integrated comforter that helps the bag adapt to variable temperatures. You can tuck the comforter's sides snugly beneath you and stay warm in temps as low as 15°F, or you can pull the comforter out to stay comfortable during the warmer parts of the year. Its unique mummy design has a women-specific fit and allows you to sleep on your stomach or sides as well as your back, which is excellent because most mummy bags only let you sleep comfortably on your back. Sierra Designs stuffed this bag with 600-fill duck down insulation that was treated with DriDown, which means even if your bag gets a bit wet, the down will fight off the moisture instead of clumping up and getting cold.

Sierra Designs built the Backcountry Bed's shell out of ripstop for durability and the liner out of taffeta for your comfort. This bag also features insulated pockets for your arms so you never wake up in the middle of the night because your hand slipped out of the bag and is slowly chilling. There's also an integrated sleeve for your sleeping pad so you never roll off of it during the night and wake up on the rocky ground. This bag is warm enough for the cold nights, versatile enough for the warm nights, and comfortable enough to keep you nice and cozy on car camping trips.

Better than sleeping at home!

  • Familiarity: I've used it several times

Interesting and intriguing design and it works! It does take up some space in the pack despite it being down, it doesn't compress as well as I'd like but it's worth it. The bag is incredibly comfortable. The sleep pad sleeve is a bit snug. My NeoAir XLite fit perfectly but with the BA Double Z. pad it was a very tight squeeze. Haven't had this out below 50 yet but it did make for a great night sleep. I'd highly recommend this bag.

Little story: When I got it, I put the kitty in the bag, thinking she'd wander, explore and get out. Instead, she settled in and fell asleep, refusing to get out. When she finally did and I packed up the bag, she came back , tried to climb into the mesh sack and when that failed, she slept next to it. So, that i guess makes two fans in my house of the bag!

Better than sleeping at home!

Wife loved it

  • Familiarity: I've used it several times

Picked one of these up for my wife so she can be a little more comfortable when I take her camping. She has always hated sleeping in a mummy bag but LOVED this bag.

We were in temps around 40, and she was very comfy in light base layers.

Kind of amazed at how well these bags sleep.
