Sleeping Bag Temperature Ratings for Nepal Treks
Choosing the wrong sleeping bag temperature rating is the most common cold-night mistake on Nepal treks. This guide decodes EN ratings and matches them to specific routes.
Sleeping bag manufacturers use EN/ISO ratings to standardise temperature performance, but the comfort rating versus the limit rating confuses most trekkers — with cold consequences.
Overview
EN ratings give four numbers: Upper Limit, Comfort, Lower Limit, and Extreme. Always buy to the Comfort rating for your coldest night, not the Lower Limit. For EBC: nights at Lobuche and Gorakshep drop to -10°C to -15°C — use a bag rated -15°C comfort. For Annapurna Circuit at High Camp (4,925m): -10°C comfort minimum. For lower treks like Poon Hill or Mardi Himal: a -5°C comfort bag is adequate. Down bags (750+ fill power) are lighter and warmer; synthetic bags retain warmth when wet. Rent or buy in Kathmandu from reputable shops — Sajilo will get you to the gear district efficiently on arrival day.
FAQ
Should I rent or buy a sleeping bag in Kathmandu? Renting is fine for EBC-level treks from established shops (NPR 200-400/day). Buying is better value if you plan multiple treks.
What about teahouse blankets? Most teahouses provide blankets, but they are often thin and shared. A sleeping bag liner at minimum is always recommended.
Planning this trip? 🎒
Don't stress about transport or guides. Sajilo offers verified cabs, luxury tourist buses, and expert guides across Nepal.
Does altitude affect sleeping bag performance? Yes — the reduced air pressure means less insulation from dead air space. Budget one temperature rating lower than the forecast temperature.
