Which Sleeping Bag Liner Should I choose?

All Sea to Summit sleeping liners are machine washable and require only your standard laundry detergent no special soaps/cleaners needed.


If you’re using a top-loader washing machine, place the liner in a pillowcase or laundry bag first to stop any cords being caught up in the impeller.


Steer clear of fabric softeners when cleaning your liner as they can affect the wicking properties of the material.


To dry your liner, it’s best to hang it on a washing line to air dry. Using a dryer could expose it to excessive heat, which can damage the fabric.
