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 

Our women's bags are designed to contour to your figure for the most thermally efficient and comfortable night's sleep 

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 quilting 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 two no-draft, anti-snag dual side zippers 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 

Create a doublewide system bag by mating two 3N1 bags 

Regular and Long sized bags available. 

Storage sack & stuff sack included
