Western Mountaineering SlingLite

The Western Mountaineering SlingLite is a hammock underquilt, not a sleeping bag — it hangs beneath the hammock rather than wrapping around the sleeper, insulating from below where a compressed sleeping pad would otherwise fail. Its shape reflects that job: 66 cm at the shoulder, widening to 115 cm at the hip, then narrowing again to 66 cm at the foot, following the natural curve a body takes in a hanging hammock. It weighs 425 g, with 225 g of 850 fill-power goose down inside a 15D silk-treated nylon taffeta shell, using continuous horizontal baffles without differential cut. There is no zipper, hood, or pad-attachment loops — none of those apply to an underquilt — and it packs down small, to 25×13 cm. Rated to a -7°C limit, its roughly 61 g-per-degree figure is efficient for the category, making it a solid three-season choice for hammock campers who want dedicated under-insulation rather than adapting a ground pad or bag to hang gear. Sized for users up to 188 cm.
