3N1 System Bags offer three bag configurations for temperature versatility with a technical, roomy sleeping space that keeps you on your pad throughout the night

Ultralight, durable materials with 850 fill Downtek water-repellent down, for those who aren't willing to sacrifice comfort for compressibility

Pad Cinch System is adjustable to a variety of pad sizes. The self-equalizing drawstring easily connects bag to pad and the middle securement feature provides extra stability

Maximum thermal efficiency is achieved when inner and outer bags are layered, using offset quilted construction to minimize cold spots

Sleep on any side using the inner bag alone and within the outer bag. Three-quarter, anti-snag, ambidextrous zipper stays out of the way when side sleeping

The inner bag design mimics our award-winning Sidewinder sleeping bag, designed for side sleepers and made to move with you from side to side

Keep your head snug and warm using the inner bag with jacket-style hood

Spacious, rectangular shaped outer bag is constructed with no-draft collar, no-draft wedge, and a single no-draft, anti-snag left side zipper with zipper garage

Ultimate comfort and additional hand warmth with hand tuck pockets at the top of outer bag

Access from top and bottom of both inner and outer bag with two-way zipper for easy temperature control throughout the night

Easy access to discreet pillow barn on pad sleeve, keeps your pillow tucked in all night
