Compression Sack for Sleeping Bag

[shoqu001]

I currently own the Women's Marmot Trestles 15 sleeping bag (Regular size, not Long) but I have been considering to purchase a waterproof compression sack for some kayak backpacking trips. I am unsure of what size I should consider getting and if it should be waterproof. What size would you recommend?

You will want something between 16-20 liters.  Personally I would go with 20L.  It just gives you a little extra room for stuffing and you won't have to break a sweat to get it in the compression bag.  Have fun on your kayak trip, sounds amazing!

I agree with @REI-KarenR , a 20L would be a nice size for that particular sleeping bag. I also think having a waterproof compression sack would be a good idea. Just in case you get a little wet! I really don't like sleeping in a damp sleeping bag. LOL

Also consider packing your sleeping bag inside out into your compression sac. This will help to get all of the air out of your sleeping bag since there is a loft layer around the outside. It will help you to compress your bag smaller!

H2O Yeah!
