Don't hesitate a bit to go higher when you've got a lightweight, warm Arrow Rock in your pack. 600-fill goose down sleeps well on Whitney or Longs and tuck stitching guards seams against an early demise due to abrasion. A draft tube and ergonomic hood seal out the cold, while a full-length Snag Free zipper allows you to adjust to temperature fluctuations. Continuous baffle construction keeps down in place, and also allows customizing the amount of insulation you leave on top of the bag.
