Clima-Wool Base Layers

Hot Chillys ranks products based on Hot Chillys warmth thermometer. Six is the least warm with a green color background, yellow is the next warmest, then light orange, dark orange, and ten is the most warm with a red color background. This product is a light orange seven on the Hot Chillys warm thermometer.

We know a bit about base layers and wool. In 1985 Hot Chillys manufactured our first wool blend base layer and revolutionized the 80's under-ski-wear market. 

Clima-Wool features a blend of mulesing-free merino wool to keep you warm, moisture transfer fibers to move moisture, and nylon to make sure you stay dry. It’s comfortable enough to live in and works hard for you when you need it.

Clima-Wool keeps you warm and comfortable during all of your outdoor activities. It’s the ultimate comfort experience, and it’s unique to Hot Chillys.

We've reinvented our Merino Wool/MTF Nylon blend in a comfortable, relaxed fit that's perfect for the hiking trail or the campfire.

Warmth factor 7 out of 10 - Relaxed fit wool/nylon blend for warmth in cold conditions
