Big Agnes Torchlight EXP Sleeping Bag vs NEMO Disco 30 Sleeping Bag

The Torchlight EXP is the warmer bag: its 0°F rating and expandable side panels suit cold-weather campers who want to add room or layers. The Disco 30 is the better pick for side sleepers and three-season backpackers, thanks to its Spoon shape, Thermo Gills and lighter packed weight. Both use 650-fill down; the Torchlight carries more fill for its warmth, while the Disco trims weight and adds venting. Owners of the Disco praise the roomy cut and draft collar; Torchlight users like the adjustable width.

• Choose the Big Agnes Torchlight EXP if you camp in freezing temperatures and want a bag you can widen or narrow with zippered side panels.
• Choose the NEMO Disco 30 if you sleep on your side or stomach and want a lighter three-season bag with venting and a pillow pocket.
