Western Mountaineering - Sycamore MF

WM sez: "It's your third day on the Colorado and you've been running rapids for as many days. The Grand Canyon looks different from a raft! It's a special place with an ancient Puebloan ruin just up the draw... If you can climb out of your Western Mountaineering Sycamore MF early enough, you might just see it before breakfast... With plenty of room and a hood just in case, the semi-rectangular Sycamore MF is made with our 1.2 ounce MicroLite XP™ to provide that extra margin in weather protection. Filled with 17 oz. of our high-lofting down this bag with 5" of loft is rated to 25° F. It sports 62" of girth at the shoulder and 46" at the foot. Not only will it zip to our mummy bags, but the zipper around the foot section lets it open up flat to be used as a comforter... This is the river runner's dream! This bag was formerly known as the "Hooded Aspen MF". Nothing about the bag has changed except its name." (Hard to improve on that description!)
Like all of Western Mountaineering's bags, the Sycamore MF is made by hand in San Jose, California. Their down is sourced from free-range mother geese who are never live-plucked or force-fed.

Product Reviews

Great bag!
Great bag. Have used it for weeks on end in the late fall, October-November, down to about 20F. Have never been cold. Bag is comfortable (I'm 5'10"). Most of the time I also use a Western Mountaineering sleep sack that fits in my hand when it's stuffed in its pouch. Properly insulated underneath, this is a comfortable, warm bag.

I can't really comment on the length of time that it takes to puff back after it's packed up since I've only compressed it when packing it to save space in the truck. I haven't yet used it for backpacking, but it does compact nicely. (I store it totally fluffed up in its large storage sack, not the stuff sack.)

I highly recommend this bag. Review by DJ
great versatile bag
I have several high quality bags. This Sycamore is a favorite as
it is lightweight and built excellent. Can close up like a warm
sleeping bag or fully open like a quilt. Best of both designs. Review by chris L.
