We pack along the Dogwood + Sleeping Bag from ALPS Mountaineering when our multi-day trek takes us from balmy summer evenings to crisp fall mornings. The quilted down top flips open to give us full access to passing breezes but also easily tucks in when the air gets a bite. A mix of hydrophobic down on the top and synthetic insulation on the bottom turns us into the perfect toasty sandwich for dipping temps in the great outdoors.
