Quick Summary

Key Details

What to Compare Before Buying

Check your backpack’s stated capacity against the listed 40-75L range, and consider whether a 21.7 x 32.7 in liner suits the gear you plan to pack. The stated load limit is about 66 lb when evenly packed; keep the contents within that limit.

Compatibility, Size and Fit

The listed capacity range is a backpack-fit guide, while the liner’s dimensions determine how much room it has for packed items. Compare both with your pack and intended contents rather than relying on capacity alone.

What Is Included

The set contains 10 CPE liners and 15 black mini elastic cord ties. The ties can be used to fold, twist or cinch an open top after packing. There are fewer ties than liners, so the set does not provide one tie for every liner.

Sort Clean and Worn Gear

For a trip, you can use a liner to keep clean clothing or sleep layers separate from worn or damp items inside your pack. The liners are also described for travel organization and storage at home; choose a use that fits the liner’s dimensions and keep packed loads within the stated limit.

Before You Decide

Confirm that your backpack is within the 40-75L range, that the liner dimensions suit your packing needs and that your load will stay at or below about 66 lb when evenly packed. Check that 10 liners and 15 ties match the quantity you want.

Using the Open-Top Design

The ties can gather the opening, but they do not establish a watertight seal. Treat a liner as an added barrier inside the backpack, not a guarantee against water entering through the opening. Use separate protection for items that must stay dry.
