How to choose a sleeping bag
Three questions decide: how cold will the nights be, how much weight and space do you have, and how tall are you? The comfort rating answers the first, the fill – down or synthetic – the second, and size M or L the third. Every one of our sleeping bags for backpacking, camping and cycle touring comes in both sizes.

Choose by season
Summer
Comfort rating 7 °C and above: Pyro 250, Tracks Spring, Mudds Summer and Blues Summer. All under Summer sleeping bags.
Spring to autumn
Comfort 0 °C to 5 °C: Pyro 500, Tracks Autumn, Mudds Autumn and Mudds Winter. More under 3-season sleeping bags.
Winter
Comfort 0 °C and below: Pyro 750 (-2 °C) and Mudds Winter (0 °C). More under 4-season sleeping bags.
Down or synthetic?
At the same comfort rating of 7 °C, the Pyro 250 down bag weighs 480 g in size M and the Tracks Spring synthetic bag 980 g. Compressed, the Pyro measures 13 x 19 cm and the Tracks 20 x 28 cm. Synthetic fill loses less warmth when damp than down and is easier to care for. For backpacking and bikepacking choose down; for camping and damp conditions choose synthetic. All models under Down sleeping bags and Synthetic sleeping bags.
Mummy or rectangular?
Eight of our nine sleeping bags are mummy sleeping bags: they taper towards the feet (50 to 53 cm wide at the foot) and have a hood, so your body has less air to warm. The Blues Summer is rectangular with a full-length zip – open it right out and use it as a blanket.
Which size?
Size M fits up to 175 cm, size L up to 195 cm. If you like room at your feet or are close to the limit, choose L. If you need extra length, our tents with extended sleeping length give you more room too.
Understanding comfort ratings
The comfort rating is the temperature at which you sleep relaxed without feeling cold – plan with this one. At the limit rating you can just about sleep curled up without feeling cold. The extreme rating is a survival limit, not a planning value. All ratings assume a sleeping mat that suits the season.
Care and repair
Store your sleeping bag loosely in its storage sack, not in the compression sack, and air it after every trip until fully dry. More under Care & Cleaning. If something is damaged, our repair service can help.
Sleeping bag FAQs
What is the best sleeping bag for backpacking?
Weight and pack size matter most. The Pyro 250 weighs 480 g with a 7 °C comfort rating, the Pyro 500 780 g at 3 °C. For colder nights choose the Pyro 750.
Which size if I am over 1.80 m?
Size L. It is designed for heights up to 195 cm and available for every model.
How warm does my sleeping mat need to be?
The colder the night, the higher the R-value. For spring to autumn an R-value of around 3 to 4 is enough; for frost we recommend 5 or more. See Sleeping mats and Insulated sleeping mats.
Do I need a sleeping bag liner?
For huts, bothies and hostels, yes. Inside your sleeping bag, a liner keeps the fill clean. Models under Sleeping bag liners.
