Introduction
Breathable Pad for Warmer Hikes
The standard insulated pad included with our backpacks can run a little warm in summer. This optional back pad adds much better airflow.
It weighs slightly more, but keeps your back cooler and more comfortable when the temperature climbs.
This page is for the THREE and ONE. For the Breathable Pad for theMINI, see the product page here.

Material
The Breathable Pad uses C-CORE, a three-dimensional mesh structure made from densely entangled polyethylene fibers.
Also used in high-quality mattresses, its springy structure helps take the edge off bumps and movement, giving you a more comfortable ride while hiking. The open construction also lets plenty of air through, dries fast, and is easy to wash.
