Synthetic, for people who will use it at home too

Marmot Trestles 15 Sleeping Bag

Synthetic fill, rated 15 °F / −9 °C, ~1.5 kg

4.4 on Amazon

Synthetic keeps working when damp and costs a third of equivalent down — it is also twice the packed size, which on a porter-carried duffel matters less than the internet thinks.

Treks we recommend this for

Not every route needs it. These are the ones where our guides would put it on your list.

The alternatives

Everything else we recommend in sleeping bags, including the ones we think suit a different trekker.

Down-filled, rated around −15 °C, with a linerWhat most people should do

The single biggest money-saver on a two-week trek

Four-season down bag (−15 °C), rented

A bag you would buy costs several hundred dollars and you need it for perhaps five cold nights. Kathmandu and Pokhara rent good ones for a couple of dollars a day, and we make nothing from telling you that — take your own silk liner and the hygiene question answers itself.

Rental shops in Kathmandu and Pokhara carry this — about usd 1-2 per day in thamel or pokhara lakeside. We take nothing from that.
