A200 ultralight mattress
"In addition to a full rethink and redesign, the A200 ultralight self-inflating mattress has a small feature that changes everything: two series of non-slip patches at the elbows and hips. Their only function is to prevent you from "sliding off" your mattress during the night. Sleeping bags often slip off self-inflating mattresses. Thanks to the patches, you sleep more comfortably and get a good night's sleep," Sébastien, product manager.
