This is the dream sleeping bag I don’t yet own. I’ve suffered too many chilly nights in my light-weight summer bag to save weight, and now know that it’s worth the few extra ounces to sleep well.

The Torchlight UL 20-degree bag from Big Agnes is plenty light, is filled with 850 fill DownTek™ water-repellent down that will maintain warmth when damp, and features expandable panels for customized fit and enhanced comfort.

The two expandable panels that stretch from shoulders to footbox give you up to 10 extra inches of room, a valuable innovation if you’re a rough-and-tumble sleeper like me. I hope to add one to my quiver of bags soon.

MSRP: $399.95 to $419.95. Bigagnes.com
