Stoic Somnus 30
Here's what other sites are saying:
After two seasons of success with its cream-of-the-crop Somnus sleeping bag, Stoic revisited the design of the main opening and changed a front zipchanging to a side zip opening for the SZ 30 Sleeping bageffectively making life easier than ever for campers and backpackers. Like previous models, this Somnus features lofty, 850-fill down insulation, a vertical baffle design that controls insulation migration (cold spots begone!), and feathery light Pertex Quantuam shell material. You won't find another high-end sleeping solution that's this easy on your back, easy to pack, and easy on your wallet.
