Frequently Asked Questions
What weight should you look for in an ultralight sleeping bag?
Depending on the warmth rating, an ultralight sleeping bag typically weighs between 500g and 1kg. Down offers the best warmth-to-weight ratio and compresses right down, making it ideal for long treks where every gramme counts.
Down or synthetic fill for an ultralight sleeping bag?
Down is warmer, lighter and more compressible — perfect for dry conditions. Synthetic handles damp better but weighs more. For ultralight trekking in dry conditions, down remains the benchmark.
Does an ultralight sleeping bag keep you warm?
Yes, match it to the season you're heading out in: choose the comfort temperature based on your nights (summer or three-season). Always pair it with an insulating sleeping mat, since cold comes mainly from the ground - otherwise your sleeping bag's warmth won't be enough on its own.
How to care for a down sleeping bag?
Store it uncompressed and fully lofted, air it out after use, keep it dry when you're out and about, and wash it rarely with a suitable product. This helps the down keep its loft, which is the key to lasting warmth.
