Sierra Designs Utopia Sleeping Bag: 30 Degree Synthetic

People have likened climbing into the Sierra Designs Utopia Sleeping Bag to being in the womb. While the feeling of warmth and serenity might be comparable, this three-season synthetic bag is much more breathable and conducive to movement than most of the wombs we know of. It weighs a reasonable three pounds, packs compactly, and boasts enough insulating power to keep you comfy during cool fall nights or high-altitude summer backpacking trips.

• An EN lower-limit rating of 34° F means that this bag is best used for summer trips in the mountains and for three-season use at lower elevations
• HeatSync synthetic insulation compresses well and retains warmth even if it gets slightly wet
• Offset Layer baffles reduce heat loss and cold spots
• Flex stretch construction allows seven to eight extra inches of girth and helps eliminate dead air space inside the bag
• Tough ripstop shell withstands trail abuse and feels soft against your tired body
• A zippered draft tube, adjustable collar, and hood seal you off from chilly summer weather
• Shaped footbox doesn't restrict your natural sleeping position
• A pillow pocket lets you insert a hoody or camp pillow (sold separately) for maximizing your sleepy times
• A zippered chest pocket holds your headlamp for your nightly trip to the designated bush
• Pad Locks hold your sleeping pad underneath so it stays put
• Compression stuff sack lets you pack the bag down to 7 x 15in

Three-season warmth with womb to move.
