The lightest, most compact, four season self inflating mattress made to date. 20% lighter than the Guidelite range they replace with the following additions: non-slip base finish; greater thermal efficiency from the Lite Foam core & a new tapered ergonomic design which rolls up super small. The introduction of a Women's specific model brings to the market an even warmer, lighter & more compact mattress specifically tapered to the needs of the female form.
