What’s so epic about Merino Wool?

Merino Wool is the OG performance fibre, crushing it since way before oil-derived synthetics arrived. Cool when it’s hot, warm when it’s not, just as epic when wet and never stinks. We’ve tapped into the natural perks of this legend, while adding a new-school spin to meet the needs of mountain bikers, skiers, snowboarders and mission-seekers. 

To ensure the highest standards of animal welfare, environmental care, and social sustainability, we use ZQRX-certified Merino Wool.

Sportswear with Everyday Flexibility

As reported by son: Cool, comfortable, washes well. Great under soccer shorts but can wear everyday alternatively.

Best Boxers!

The merino boxers are awesome. Once you start wearing them you won’t want any other brands!
