FLEXTAILGEAR R05 Insulated Sleeping Pad 5.6 R-Value 4 in 77 in 19.6 oz Orange

Ultralight Insulated Sleeping Pad

The FLEXTAILGEAR R05 is an inflatable sleeping mat tested to ASTM F3340-22 standards with a 5.6 R-value. It measures 77 in long and 4 in thick when inflated, weighing 19.6 oz (555 g). The pad uses a reflective layer inside a stable chamber structure to reduce heat loss from cold ground and is made from tear-resistant nylon fabric with a compact packed size.

Backpackers Needing Warmth Without Bulk

This pad suits solo hikers and backpackers who want dependable four-season insulation in a lightweight package that packs down small. The 5.6 R-value handles cooler nights while the 4 in thickness cushions uneven terrain for back and side sleepers. Campers who prefer self-inflating foam mats or require a wider sleeping surface should consider other designs.

5.6 R-Value ASTM Tested Insulation

The decisive specification is the ASTM F3340-22 tested 5.6 R-value, which quantifies the pad's resistance to conductive heat loss. This figure determines whether the mat provides enough thermal protection for your expected ground temperatures and season length. Match the R-value to your coldest night conditions to decide if this is the right part.
