If you’re looking for a synthetic sleeping bag that’s not too weighty but is going to keep you warm on colder treks, this bag is a wicked options. It isn’t the lightest or the smallest because it is synthetic, but it’s fantastic for what it’s working with. It also ends up much more durable and able to withstand moisture as well, which is where down falls short. It’s super cozy and adjustable through zips and drawstrings, and has been designed to be great for side sleepers as well as front/back sleepers. If you’re not a down fan but you need a good, reliable, warm bag for your tramping adventures, I would definitely point you towards this sleeping bag.

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.
