The Robens Air Impact 38 is a lightweight inflatable sleeping mat designed to give campers a comfortable sleep surface without adding bulk to their pack. Its compact profile and modest weight make it a practical choice for those who want a usable sleep pad on multi-day hikes or summer trips.
Constructed from 100% nylon, the Air Impact 38 provides 3.8 cm of cushioning to help relieve pressure points, while weighing in at 705 g—placing it in the light category for backpacking mats. At 183 cm long and 51 cm wide, it fits neatly inside most tents and offers enough space to stretch out without taking up too much floor area.
The mat’s R-value of 3.1 indicates its level of thermal resistance, which reflects how effectively it insulates against ground cold. With this rating, the Air Impact 38 helps retain body heat through cool spring, summer and autumn nights, making it well-suited for three-season use.

Robens says about the Air Impact 38
The Air Impact self-inflating mats are designed with a tapered shape, providing extra space for the upper body while saving weight by reducing width at the legs where its less needed. The lightweight ripstop nylon exterior and diamond-profile core reduce weight and pack size, making this mat ideal for adventurers with limited space, such as trekkers, cycle tourers, and kayakers. The Air Impact also features the flat, low-profile Peak Valve, compatible with a Pump Sack, for easy and efficient inflation and deflation.
