When it comes to backpacking-friendly sleeping solutions, mummy bags are hard to beat. They’re easy to haul, can often keep you warm even if you don’t have a tent, and they can help slim down the rest of your kit. The big tradeoff is that they can be a bit claustrophobic. Big Agnes may have just fixed that issue, however, with their lineup of Torchlight expandable mummy bags.
This new collection includes eight sleeping bags in total — four for men and four for women — which slot into a trio of categories: 30-degree-rated, 30-degree-rated ultralight, 20-degree-rated, and 20-degree-rated ultralight. And while they all feature a bevy of shared features — ranging from DownTek waterproof down to integrated pillow hoods — the star of the show is undoubtedly the custom expandability. You see, all of these bags feature side zips that allow you to expand them up to 10″ at the shoulders, feet, or down the entirety of the bag. Better still, they can be expanded without losing any warmth, as the expansion functions entirely on the outside of the bag. The Big Agnes Torchlight expandable mummy bags are available now ranging from $280 to $370 depending on size and style.
