Merlin Mens Outlast Base Layer Trousers

A baselayer regulates the temperature of your skin to help keep you warm when its cold and cool when its warm. The MERLIN OUTLAST base layer does this but makes an even better job of it. This is down to the OUTLAST phase change material built into the garment. Developed by NASA, worn by you!

Outlast® technology, originally developed for NASA, utilises phase change materials (PCM) that absorb, store and release heat for optimal thermal comfort.  Outlast® technology is comparable to ice in a drink; as it changes from solid to liquid, it absorbs heat and cools the drink, keeping that drink at the desired temperature for longer. Outlast® phase change materials work in the same way, but are microencapsulated to be permanently enclosed and protected in a polymer shell. We call microencapsulated phase change materials Thermocules™.

This encapsulation process makes the Thermocules™ exceptionally durable for many applications. These Thermocules™ can be incorporated into fabrics and fibers and have the capacity to absorb, store and release excess heat.  This gives any product containing Outlast® technology the ability to continually regulate skin’s microclimate. As the skin gets hot, the heat is absorbed, and as it cools, that heat is released.

Outlast® technology is not wicking technology, which manages moisture by reacting to your sweat and pulling it away from the skin. Outlast® technology will proactively manage heat while controlling the production of moisture before it begins. That's the Outlast®

Not too hot, not too cold. Just Right!
