The test uses a heated, sensor-equipped manikin in a climate-controlled room, providing standardised ratings: Comfort, Limit, and Extreme. The “Comfort” rating is for women, and the “Lower Limit” is for men. This test is intended to guide what you can expect in the field. Your actual warmth may vary depending on clothing, shelter, and conditions, but these ratings ensure you can plan your adventures with confidence. - title: Care Instructions content: | If you notice your sleeping bag doesn’t feel as warm as it used to or it’s starting to smell like your base layers after a multi-day hike, it’s probably overdue for a wash. We recommend washing your down sleeping bag about once a year if you’re using it occasionally, or more often if you use it regularly.
