Description
xHome-style comfort on the trail
When night settles in at the campground, your sleep setup should feel familiar and comforting. Western Mountaineering’s Sonora Sleep Liner uses soft 100% polyester to caress your skin, offering a touch of warmth and breathable comfort without adding bulk. It’s designed to work with your sleeping bag or quilt, and with your camp mattress, to enhance warmth and moisture management with a light touch.
Designed to work with your sleeping bag or quilt, this liner helps strike the right balance between warmth and moisture management. It’s lightweight enough for backpackers to tuck into a pack, yet sturdy enough for repeated trips over many seasons.
Warmth without bulk
The mummy long version weighs about 5 oz, while the regular taper version clocks in around 6 oz. That featherweight profile can be enough to supplement a chilly night or to extend the life of your main bag by keeping dampness at bay.
Moisture control and fresh feel
With the right microclimate inside your sleep system, you may find your nights are more comfortable—without relying on heavy gear. The liner is machine washable, so you can refresh it after a sweaty trek or a campfire night, leaving the scent of outdoors behind.
