Designed for high altitude overnights, the Sea to Summit Alpine ApII down sleeping bag keeps your nights warm when trekking the Himalayas or touring the Alps hut to hut.

High loft, premium 850-fill-power European duck down offers superb warmth with minimal weight; Ultra-Dry Down™ water-repellent treatment protects down from moisture
Ultra-Dry Down is a water-repellent polymer treatment applied to the 850-fill down; Ultra-Dry Down retains 60% more loft and absorbs 30% less moisture than untreated down
With a European Norm (EN) lower-limit rating of 5°F, the ApII bag will help keep you warm in all seasons, including winter
Shell fabric is constructed of a 20-denier ripstop fabric treated with a Durable Water Repellent and a non-woven silicone encapsulated fabric
Innovative shell manages condensation, moving moisture vapor outward through down and siliconized barrier; shell repels water and protects the loft of the bag
Lining is a breathable, durable 20-denier polyester fabric with a soft touch
Contoured mummy shape is cut with a fitted hood, broad shoulders and large chest (to accommodate layering of clothes); generous room around knees ensures comfort when turning
Upper side of bag is differentially cut so that the inner layer is smaller than the outer layer; this creates a consistent thickness of insulation and helps prevent cold spots
Lower side is cut in reverse so that the inner layer is larger than the outer layer; this allows down to loft up, filling spaces around body in warmth
Oversize draft tube backing the 2-way zipper keeps the warmth in and the cold out; zipper is backed by stiff, antisnag tape for smooth operation
Anatomically tapered foot box allows feet to rest naturally; it also preserves loft and allows down to drape close to feet for warmth
Oversize collar drapes comfortably over neck and shoulders, sealing out drafts; dual elastic adjusters
Preventing cold air from seeping in, offset baffle construction allows the goose down to remain fully lofted and keeps it from shifting
Interior zipper security pocket is great for stowing small essentials, alleviating middle-of-the-night fumbling and preserving battery performance in cold weather
Sea to Summit Alpine ApII bag comes with a Ultra-Sil® compression sack, an oversize mesh storage cell and a large cotton sack
European Norm (EN) is an independent third-party temperature rating, allowing accurate comparisons across brands with other EN-rated bags

Comments about Sea to Summit Alpine ApII Sleeping Bag:

I've been waiting for years to replace my 20-year-old down sleeping bag. All of the new developments in down and textile technology get better every year. I'm an admitted gear geek, and research the heck out of the bigger-ticket items before making an investment. What I love about this bag is that I didn't need another layer outside (a bivy bag), it handles the classic condensation issues which reduce loft and warmth in down, and it's under $1K with lots of high-quality, high-tech features. Depending on the layers you sleep in, the bag can seem snug (what sleeping bag is roomy anyway?), but I felt as toasty as I needed to be. My body temps are never warm enough in the winter, so I also purchased the Thermolite Extreme sleeping bag liner in case I'd be chilly - even this toasty bag! Good news is I didn't need it but have it for an even chillier time. The first trip with this bag was about -5F winter camping at Rocky Mountain National Park.
I've camped in all sorts of temps and used hot-water-filled Nalgene bottles to stay warm in the Himalayas, and I'm confident about where I can take this bag when the temps go low. I would take this bag on a hut trip, on a winter camping tent trip, or on a damp and chilly car-camping trip if I'm not sure how low the temps will dip - it packs down small enough. While some people might think this is too warm, if you're female and sleep cold, this bag is worth it for many adventures!
