GI USMC Issue Therm-A-Rest Accordion Sleeping Pad

This is a genuine US military surplus Therm-A-Rest sleeping pad, or referred to as The Improved Sleeping Mat (ISM) by the USMC. This pad is designed to be easily folded into a more compact form for carrying and stowage by Marines. The “accordion style” fold is durable, while providing improved comfort for quality of sleep without increasing weight.

The composition is a closed-cell crosslinked polyethylene foam that is pre-formed with full width folds. The flat 72″ x 23″ mat can be easily folded in an accordion fashion into a 5″ x 5 1/4″ x 23″ rectangle at 605 cubic inches which allows for quick packing and easy stowage. The mat is secured in its folded shape with two attached elasticized loops. The packed mat reduces packed volume by 20% and saves packing time by lying flat. The mat retains the insulation, padding, reliability, and durability. Weighs approximately 1.3lbs.
