You've made it this far on your Appalachian expedition, you're almost to Maine and you've picked up your pace. When really pushing yourself, you can make it twenty miles in a day, and when you lie down for the night the one thing you won't sacrifice is a good night's rest. The Sierra Designs Nitro UL 800 DriDown 20 Degree Down Sleeping Bag never felt like it was weighing you down, and it certainly warms you up so you can get some well-deserved snoozing all night.. This bag is filled with soft and creamy Dridown, and it will stay lofty and warm at cold temperatures, even if you encounter some rain on the trail. Designed with backpacking in mind, Sierra Designs created this lightweight bag using 15D nylon and 800 fill down, yet still with a generous cut for a little more room to get comfy after a long day on the trail. Plus they've decreased the baffle size to five inches so that the down doesn't have as much room to shift around on you in the middle of the night, ultimately creating a warmer experience. It's lightweight enough for your long trip, and still offers great amenities such as a foot vent for warm mornings and anti-snag zipper tracks. Look forward to sleeping the whole night through, while dreams of your next pint dance in your head.
