Buying Guide
What temperature rating do I need?
Choose a bag whose rating matches the coldest temperatures you expect. Extreme-denali missions typically require ratings well below freezing (e.g., -10°F to -30°F). For milder trips, 10°F to 20°F can be adequate.
What construction matters?
Look for layered insulation (two-layer offset designs help prevent cold spots) and a robust shell (nylon ripstop is common) for durability in rugged environments. A hood and draft tubes around zippers add warmth retention.
How much bulk and weight are acceptable?
Trade-offs exist between warmth and packability. mummy shapes save space and heat more efficiently, while rectangular or oversized bags offer comfort and roominess at the cost of bulk.
What features improve comfort?
Inner linings that feel soft, moisture management, and a secure hood with drawstring are practical comfort features. Zipper efficiency and anti-snag designs help prolonged use on multi-night trips.
Price vs. performance
Premium insulation and durable shells increase price but improve warmth and longevity. Budget options often provide adequate winter performance for light use but may underperform in extreme cold or rugged weather.
