Master a year-round sleep system: translate temperature ratings to real nights, match pad R-value and shelter, and see which bags truly span the seasons.
Learn how shell fabrics, RET/MVTR, and fit shape moisture control in sleeping bags, with metrics and tests to prevent clamminess and sleep dry in humid camps.
Preserve sleeping bag loft and warmth off-season: air 72 hours, avoid compression and plastic, use breathable cotton sacks, and do quick quarterly inspections.
Cut through bag ratings with a 5-question system that matches Bishop Pass or Phantom to your pad, shelter, climate, and body type for real cold-night warmth.
