Big Agnes Torchlight EXP Sleeping Bag vs Marmot Hydrogen 30 Sleeping Bag

The Torchlight EXP is the warmer, roomier bag: a 0°F rating, expandable side panels that widen the shoulder and hip girth, and a pad attachment system. The Hydrogen 30 is the lighter, more packable choice, with 800 fill power down and a 30°F rating in a bag that weighs about a pound. Buy the Big Agnes for cold-weather camping and for a bag you can open up on mild nights; buy the Marmot for fast-and-light trips and warm-weather backpacking where weight matters most.

• Choose the Big Agnes Torchlight EXP if you sleep cold, camp in shoulder seasons or winter, and want a bag that adjusts its width through the night.
• Choose the Marmot Hydrogen 30 if you count grams, backpack in mild conditions, and want a compact down bag that disappears into your pack.
