Sleeping Bag Choices for Trekking Seasons
Comfort at altitude depends on rating, insulation type, and nightly routines. A sleeping bag is part of a full sleep system, not a standalone fix.
Understanding Ratings
Use comfort ratings, not survival ratings, when planning for Himalayan routes. Night temperatures vary with season, altitude, and lodge insulation.
Going too light on sleep warmth can quietly increase fatigue over multiple days. Protect recovery, not just pack weight.
Down vs Synthetic
- Down: lighter and highly packable, but needs moisture care
- Synthetic: bulkier, but can perform better in damp conditions
Sleep System Tips
Use dry base layers for sleep, keep socks dry, and ventilate bags each morning. Consistent routines improve warmth over long itineraries.
