If you are looking for a very decent quality sleeping bag that is lightweight but don't want to give up on comfort, the Sea to Summit Ascent range is a fantastic place to look!

Though the shape of the bag still tapers at the bottom, the sleeping bag is much more rectangular than most mummy bags. The Free-Flow zip provides flexibility with temperature adjustment whether you want to use you bag as a quilt, stick your feet out or stick out your arms to read a book. The high quality 750+ down fill allows this bag to remain decently lightweight while still performing in cold temperatures. When going with a higher warmth rating like the -9 it usually means you might be using it on colder, longer nights where comfort will be key to a good sleep. The -9 would be a good choice for someone going on adventures all year long.

Fit tip:

Nice and roomy, good for side sleepers or people who tend to move around in their sleep.
