Marmot Always Summer 40F Sleeping Bag

Item No.   10237063

The Marmot Always Summer Sleeping Bag is a 40 degree sleeping bag for warm weather camping. The 650 fill power down is treated with Down Defender for water-resistance on damp trips and then encased in lightweight nylon ripstop LT fabric. Weighing in at 2 pounds (regular length), stuff the bag into the included stuff sack and you’ll hardly notice it in your pack until it’s time to tuck in for the evening. Pull the 5-baffle hood in with the ‘feely’ draw cords and you’re set for counting sheep.
