SD Arrow Rock 45º Down Warm Weather Sleeping Bag

By Rick Shandley

Big on comfort and light on weight, the Sierra Designs Arrow Rock 45 is the hot ticket for warm weather backpackers. Weighing in at just 2-pounds, 2-ounces, the Arrow Rock is built with Sierra Designs’ Flex construction, allowing the bag to move with you while you sleep. This eliminates dead airspace to help keep you warm.

Arrow Rock’s 600-fill goose down is light, warm, and super compressible. In fact, this bag stuffs down to a real packable 7-inch by 17-inch stuff sack, which makes it perfect for slipping into a sleeping bag compartment in your pack or nestled in amongst your gear in the main pack compartment. A full-length zipper regulates temperature while a zippered chest pockets keeps your valuables close at hand.

We’ll be doing a product review on the Sierra Designs Arrow Rock 45 in coming weeks.  As the weather chills down towards Fall and Winter, it’s our intention to use this bag along with additional insulation such as tent, clothes, jacket, etc. to learn how far into the seasons we can be comfortable in it.
