The Katabatic Gear Sawatch 15 is one of the lightest 15 degree sleeping bag we've ever tested. It's very warm, very comfortable, and very light. This is a warmer version of Katabatic Gear's Palisade bag. We suggest reading that review for details on how and why the Katabatic quilt system is the best we've tested.
Choosing the right Katabatic quilt is challenging. Our testers reach for the Palisade on nearly every three-season trip and grab the Sawatch for trips with nights that will consistently be below freezing. The Alsek, which has a 22 degree rating, lies between these. The right bag will depend on how warm or cold you sleep and what clothing you bring. We've found that wearing a lightweight insulated jacket in the Palisade is plenty toasty. But the Sawatch is much warmer and only weighs a few ounces more.
The Sawatch is a better choice if you want one bag that can be pushed into winter conditions with a down jacket (if you do that we suggest getting a wider version unless you're really skinny- it's important to leave space for your down jacket to fully loft). This bag is ludicrously warm for its weight and amazingly versatile. See the specifications table above to compare its fill and material weight to the other bags tested.
Katabatic Gear quilts use the same general design but have different amounts of down fill. From left to right: Chisos 40, Palisade 30, Alsek 22, Sawatch 15, Blackwelder 0.
Although this pad is lightweight, it doesn't offer as many benefits as our Top Pick for Lightweight, the NeoAir XLite.
