Here's what other sites are saying:
Once late spring hits the mountains, your ambitions shift to the high alpine reaches; toss the 15-degree down Stoic Vamp 15 Sleeping Bag in your pack to ensure a good night's sleep above 10,000 feet. The 650-fill down locks in your body heat in bivvies, tents, and drafty shelters without adding too much weight or taking up too much space in your pack. And since it's made with tough Pertex Microlight fabric, it endures through the challenges of your ambitious expeditions as well as your spontaneous escapes to the desert.
