If you spot a bag with oddly cheap “comfort” or “survival” temperature ratings, definitely double-check if that fits your trip plans-sometimes clearance models exaggerate warmth. Inspect zippers and seams if you can, since those are common weak points in budget bags. Also, if you see “rectangular” shape and you’re planning on colder temps, keep in mind those are usually less efficient at keeping warmth compared to mummy-style bags!
