Ajungilak Beito fleece, Sleeping bag inlet
The inlet have been used a very cold weekend in January.
If you want to have a warmer sleeping bag and you're not willing to buy a new one makes this inlet perfect. Now you can use your bag in colder weather because the inlet increase the insulation properties with about 5 to 10 degrees. You can also use the inlet separately from the sleeping bag when it's warmer outside. The price? About 300-400 SEK and the weight is 850 grams.
One thing that isn't so good is that a lot of gras, dust and other things will stick to the fleece.
