• More affordable than Dyneema
• More durable than a trash bag
• Outer abrasion layer helps protect your pack liner for years of use.
• Lighter than 2.92 Dyneema. About the same weight as 1.43 Dyneema. Only slightly heavier than 1.0 Dyneema

Sizes (flat dimensions)
Note about sizes. Check the internal volume of the main body on your pack. To verify you have the right size, lay your pack down and flatten it out. Measure a flat dimension width. Your width is most important. You want your pack liner to be just a little bit wider than your pack. The height is not as important as you will most likely store a tent and other items that don't need protected in the bottom of your pack underneath your pack liner.
