What To Consider When Choosing A Lightweight Sleeping Bag

sleeping bag for cold weather inside a tent

When you are looking for the best ultralight sleeping bag that will keep you comfortable while camping, there are a few things should consider.


The fill of the sleeping bag is what insulates it and what keeps you warm. Most lightweight sleeping bags use down because it’s not heavy or bulky, but still provides plenty of warmth. The downside to down is that if it gets wet, it takes a long time to dry.

Mold and mildew can also grow on it, and you usually have to hand wash, and air dries it. Synthetic fill materials are typically heavier, but they are also often water-resistant and easy to clean.
