Big Agnes | Diamond Park 15˚

Why we stock this? If you want the comfort of a bed away from home, look no further. This is the go to motorcycle sleeping bag for riders who don't mind sacrificing a little packing space for the comfort this bag offers so that you can toss, turn, and roll in the bag all night without worrying about coming off the sleeping pad, because the bag attaches to it. If you ride a middleweight to large motorcycle, you shouldn't have a problem finding space in your panniers or bags for this bag. Smaller bikes and dual sport riders should check the compressed volume to ensure they will have the space to carry it without over packing. 

We HIGHLY recommend buying compression straps or a compression bag for these bags. The stuff sack included is 20" x 9" but can be compressed down to 11" with compression bag. 20x9" is about 20 Liters.

If you really want the mother of comfort after a riding hard all day, this is the bag for your motorcycle camping adventures. The all NEW versatile Diamond Park Series down bags are Big Agnes System bags featuring the Flex Pad Sleeve to accommodate both 25 and 30-inch wide pads. Cut tall and wide for those who like a little more room to move around at night, or for campers of a larger stature who want a bag that sleeps just right. Ideal for base camps, car camping or an overnight on your friend’s floor, this is your go-to bag for a good night’s sleep. Double zippers can be zipped off completely to create a comforter, or can be zipped together to create a mummy bag. The Park bags’ unique quilt-like construction turns your bag into a backcountry bed so comfortable, you won’t want to go home!
