For Philmont and the Appalachian Trail (AT) I have chosen to use the ALPS Mountaineering Clearwater sleeping bag. The decision came mostly because I found it for a really great price.
The ALPS Mountaineering Clearwater sleeping bag is a synthetic bag that is rated at 35 degrees, 21 ounces of fill weight, and weighs in at 2 pounds 11 ounces. Its warm and works great. My only negative comment is that I am roughly 5’6″ tall and my feet hit the bottom of the bag. So those of you who are taller might want to get the “long” bag. This sleeping bag retails for $90 for the regular and $100 for tall. For the price its a great buy no matter what your camping situation calls for.
I have taken it on several practice hikes and I have never had any issues with getting cold at night. It packs down into a nice compact little ball with the provided compression bag. Only concern with the compression bag is that the one that comes with is not water proof. It does however appear water resistant. I have not tested it however. I do plan on getting a waterproof lighter weight compression bag for my trips however.
Here is what ALPS Mountaineering has to say about the Clearwater sleeping bag.
The Clearwater series sleeping bags are made with MicroX+ insulation. MicroX+ Insulation consists of multiple denier staple-length fibers that have a siliconized finish for maximum insulation, loft, and compactness. It is an ultra lightweight insulation that has a tremendous weight-to-warmth ratio. The Clearwater uses a 2-layer offset construction, sometimes called a “bag within a bag.” The contoured hood and mummy shape helps seal up your warmth and keep you warmer. The Clearwater is a great backpacking sleeping bag to take along on your hikes that won’t take up all the space in your pack or weigh you down.
