BackpackerandNo.8217;s Mummy Sleeping BagThe Suisse Sport Adventure extra-small sleeping bag is ideal for long treks when a few inches or pounds can make the difference between a pleasant hike and an unbearable slog. The mummy bag is ultra-compact, compressing down to 12 by 7 by 7 inches when in the stuff sack. How small is that? Well, it’s petite enough to hold in the palm of your hand. That means you can easily fit the bag in your hiking pack without using up a third of your pack space. At the same time, the bag is warm and comfortable, with a 100-percent polyester ripstop outer and inner lining, a double-layer construction, and a 700-gram Micro Tekk.7 high-performance microfiber insulation. The construction materials ad up to a 30-degree F temperature rating, making the bag a good choice for summer, spring, and fall camping trips. Other details include a full chest baffle, a draft tube, and a utility pocket. The Adventure sleeping bag measures 29.5 by 84.5 inches (W x L) when open and weighs 2.9 pounds in the stuff sack. The bag is also machine-washable for easy cleaning.
