Marmot Camp & Hike Yolla Bolly 30 Sleeping Bag Botanical Garden/Kelly Green Left Zip Double Wide. You’ll stay warm and dry thanks to the lofty 650-fill-power-down insulation and water-resistant Down Defender treatment. This three-season multitasking sleeping bag turns into a quilt thanks to its wrap-around zipper that completely opens. The soft fabric at the inside hood provides an extra touch of comfort while the silicone-printed back reduces slipping when on top of a pad. Tuck small items into the internal stash pocket for easy access.
