Merino Wool Socks Built to Last & Guaranteed for life

We make merino wool socks to inspire you to get outside. Made in the USA, our breathable, comfortable and durable merino wool socks are backed by a lifetime guarantee.

We’ve all had that nagging feeling — miles into a hike, or several runs into your day on the slopes — where something just doesn’t feel right. A bunched toe, a slouched sock, a rubbing seam: the tiny distractions that get on our nerves. 


With Cloudline socks, you can enjoy your adventures without those annoyances. Because what you wear shouldn’t slow you down — it should support you all the way to the Cloudline.

As an outdoor adventurer, you need your gear to work as hard as you do. 

The glory of summiting a mountain peak shouldn’t be shadowed by a week of hobbling on blistered feet. Feel as inspired on your final mile as you did on your first with Cloudline moisture-wicking merino wool socks. Stay dry, cool, and comfortable on the most epic of adventures.
