It might just be that you enjoy the finer things in life, or it might be that you can't understand why your friends love camping so much when it means a terrible night's sleep, in a cramped sleeping bag, on the rock-hard ground. No matter what your reason is, there's always a good reason to opt for the Big Agnes Diamond Park 0 Down Sleeping Bag, an opulent sleep system designed to be lush, plush, and soft to the touch, so the next time you go camping you'll drift right off to sleep. With a wide long construction, the Diamond Park gives you plenty of wiggle room and eliminates the sardine-in-a-can effect while the elastic hood doesn't restrict your head movement when you're zipped up tight for the night. The flex pad sleeve secures your sleeping pad to the back of your bag, stopping your mattress from slipping away five minutes after you fall asleep, and the dual-sided zippers let you decide how you want to get into and out of your camp bed each night. Big Agnes even gave you the option of zipping off the entire front of the bag, turning it into a cozy camp quilt for extra chilly nights around the fire, which makes the Diamond Park the most versatile and essential item in your camp kit.
