Description

The Sim Lite 3.8 Forest is a self-inflating mattress from the brand Exped, ideal for camping and Bivouac in three seasons thanks to its R-Value of 3.4.

Its 75D brushed recycled polyester surface with TPU lamination offers a soft feel and good abrasion resistance, while the 14 kg/m³ PU foam insulation provides excellent protection against the cold from the ground down to -5°C. The honeycomb structure optimizes comfort by distributing weight evenly.

This Oeko-Tex®certifiedmattress is designed with an eco-friendly approach using recycled materials, guaranteeing quality and respect for the environment. Its rectangular shape and thickness of 3.8 cm provide good support for restful nights in the great outdoors. Storage bags are included for easy transport and storage.
