Sighing with happiness as you zip yourself into the Therm A Rest Capella 32 Degree Synthetic Women's Sleeping Bag is something your tent mate is just going to have to learn to deal with. After all, it's not your fault that the Capella is lined with soft and warm ThermaCapture polyester, or that it features EraLoft synthetic insulation to keep you cozy while the night hovers around freezing. Synthetic insulation stays warm when it's wet, something that down doesn't do, but Therm a Rest treated the Capella with a water repellent DWR coating for extra water protection just in case.Therm a Rest also designed the bag with its Toe Asis foot warmer pocket, which uses an extra internal baffle to form a small and warm compartment around your feet, and a draft collar and tube to prevent cold air from leaking in around your neck or through the zipper. A cinch down hood seals tightly around your head, while the SynergyLink pad connectors keep you from sliding off your pad and onto the cold ground. A zippered external pocket provides a convenient spot to stash a light when you're catching Zs.
