    Ultralight comfort revelation.

    With the Sierra Designs Cloud 20 Degree 800 DriDown Sleeping Bag, gone are the days of sacrificing comfort for ultralight efficiency. Now you can enjoy cloud-like comfort after long days of trekking, without being burdened with excess weight and bulk on the trail.

    Its innovative zipperless design features a flap that lets you get in and out easily, but wraps around you when you're lying down in order to seal in precious heat. On warmer nights you can simply push the flap out of the way to vent your core. 800-fill DriDown insulation and 15D fabrics keep weight to a minimum while still packing plenty of warmth, and the down is treated for water-resistance to keep damp nights from leaving you shivering. A half-sleeve on the underside of the bag secures your sleeping pad to create one integrated unit that offers warmth retention and comfort.

    Another ingenious features it the self-sealing foot vent, which lets you simply raise your knees and poke your toes out when you get stuffy, so you can cool off without messing with any pesky zippers. On the flip side, the adjustable hood easily cinches down to keep your head warm on frigid nights. Considering this bag's innovative design, reasonable price, and frankly incredible levels of warmth and comfort considering its weight, it doesn't seem hyperbolic to call the Cloud 20 a revolutionary achievement.

    No zippers is a dang good thang

    • Familiarity: I've used it once or twice and have initial impressions

    Can I tell you how nice it is to sleep like a baby, and not cry like one trying to get out of your bag in the middle of the night only to snag your zipper? No zipper, bed like qualities with a blanket style “top lid”. Haven’t tried it in real cold weather yet, but it’s done well so far at mid 30-mid 40 level since you can pull the blanket part off, and or vent your feet! Recommend sea to summit insulated pad for this as there is very little insulation in the bottom part of bag(mainly just back area...bottom part is ok). Meant to be a system so don’t skimp on your pad or you’ll regret it.

    Too Comfortable

    • Familiarity: I've used it several times

    I really love using this bag. I move around a lot in my sleep and the sleeve in the back keeps this bag on my pad. With the cool way it opens, it is also really easy to get in and out of.
