DESC: The Big Agnes Summer Park 15-Degree Down Sleeping Bag is an ideal cold-weather sleeping bag for campers who like lots of elbow room. With a massive 80.5in shoulder girth, the Summer Park sleeping bag is made for pure comfort. Insulated with 650-fill down, it keeps you cozy to 15F and even has a built-in pillow pocket where you can stash a fleece and create a soft pillow. Like all Big Agnes sleeping bags, the Summer Park only has insulation on the top side, replacing the useless bottom insulation with a sleeping-pad sleeve where your pad stays secured through the night. Designed for casual camping, the Summer Park sleeping bag has a full hood and draft collar to handle really cold weather in case your sunny weekend turns into something a little chillier. *Compatible with 25 x 78in rectangular pads Bottom Line: Get lots of room and three-season comfort from the Big Agnes Summer Park Down Sleeping Bag.
