Description
The COSY CAMP Lightweight NT Egg Foam Sleeping Mat is a compact closed-cell foam sleeping mat designed for camping, hiking, backpacking and everyday outdoor use. Its distinctive egg-crate surface combines cushioning, insulation and airflow while keeping the mat lightweight enough to carry on the outside of a backpack.
Made from IXPE foam with an aluminium foil layer, the mat helps reduce heat transfer from cold or damp ground while providing a softer sleeping surface than a basic flat foam mat. The raised egg-shaped cells trap pockets of air and compress under body weight, helping improve comfort without adding unnecessary bulk.
At approximately 380 g, the single-size NT Egg Foam Mat is an easy addition to lightweight camping setups and can also be used as a tent mat, picnic mat, rest mat or supplementary insulation underneath another sleeping mat.

Egg-Crate Comfort & Support
The NT Egg Foam Mat uses a three-dimensional egg-crate structure rather than a flat foam surface.
The raised cells compress individually beneath the body, helping create a more cushioned feel while maintaining supportive foam underneath. The valleys between the raised cells also retain small pockets of air, contributing to insulation without significantly increasing the overall weight of the mat.
This construction makes the mat particularly practical for campers who want more comfort than a basic flat foam pad without moving to a heavier inflatable sleeping mat.
Lightweight IXPE Foam
The mat is made from IXPE closed-cell foam, selected for its combination of low weight, flexibility and resilient compression.
Unlike inflatable sleeping mats, the foam structure contains no air chambers, valves or pumps that can puncture or fail in the field. Simply unfold the mat and it is ready to use.
The foam rebounds quickly after pressure is removed, helping the raised egg-crate structure retain its shape during repeated camping use.
Insulation Against Cold & Damp Ground
Sleeping directly against the ground can lead to rapid heat loss, particularly during cooler nights.
The closed-cell foam helps slow conductive heat transfer, while the aluminium foil layer provides an additional reflective barrier. Together, these layers help separate your sleeping bag and body from cold or damp ground conditions.
For colder-weather camping, the NT Egg Foam Mat can also be used underneath an inflatable sleeping pad as an additional insulation and protection layer.
Compact Accordion-Fold Design
The mat folds along pre-formed sections rather than being rolled.
When packed, the single-size mat measures approximately 60 × 13 × 12 cm, creating a compact rectangular bundle that is easy to secure to the outside of a hiking pack or store with other camping equipment.
At just 380 g, it provides ground insulation and cushioning without adding substantial weight to your camping load.
More Than a Sleeping Mat
The lightweight closed-cell design makes the NT Egg Foam useful well beyond overnight sleeping.

-
A tent sleeping mat
-
A supplementary layer beneath an inflatable mattress

Care & Use Instructions
