Big Agnes

Whalen 20 Synthetic Sleeping Bag

A technical bag for those who prefer a traditional mummy shape to that of the rectangle, the Big Agnes Whalen 20 Synthetic Sleeping Bag offers adaptive, steadfast warmth on your next cool-weather camping trip. The Whalen features a design that makes it ideal for camping in wet, chilly conditions—much like those found in the Northeast or Northwest, and the 20-degree rating is versatile enough to handle mid-spring all the way to mid-autumn camping conditions. A ripstop exterior is lightweight, breathable, and highly durable, while the soft polyester lining is reminiscent of your favorite comforter back at home base, making your sleep all the more amenable and homey. The synthetic insulation ensures you stay warm in temperatures as low as the twenties and is designed to keep you warm even when wet. Meanwhile, the mummy shape does its part to trap your heat and cut down on wasted space. Plus, this bag has liner loops for easy hanging when you're not using it.
