Storing your liner properly is like storing your favourite bottle of wine. It needs to be kept in a cool, dry place. Try not to squish it too much and store it in a bag that contains it but doesn’t smush it. This will help maintain its shape and quality, ensuring that it’s ready for your next adventure!

When storing your liner, keep it in a place that is not too hot or exposed to either warm or cold weather.

Accidents happen, and your liner might get a tear or a hole. No stress, repairing your liner is as easy as patching up a bicycle tire. Use a patch like GEAR AID Tenacious Tape, give the area a good scrub, and use a sturdy thread and needle for sewing.
