25°F/-4°C rating when paired with comparable upper body warmth. Alpine Climbers, lightweight backpackers, and anyone with a compact stature might find the Semilite very useful. It was designed as a zipperless elephant’s foot, which is a 3/4 length bag or hip length bag depending on your height, intended for use with a comparably warm parka for a lightweight alpine sleep system. It packs small and weighs less than a pound, but it is fully baffled and substantially insulated with 850+ fill power goose down. Simple and functional, warm and light, our Semilite is perfect for alpinists, bikepackers or fast and light trail blazers. It could also be used as a bag on its own for lean to medium bodied outdoor enthusiasts that are less than 5 feet tall.
