Test Our Natural, Breathable Summer T-Shirts!

I ordered one size up as advised in the product description and it fits perfectly. I love the stripes. Have not yet worn it on a run due to weather but I love wool and expect it to perform well.

Feel amazing on. True to size and love the two side pockets. Will purchase again.

Reliable brand. Great quality. Australian. This would be the fifth pair purchased for this household. Highly recommend.

Very comfortable and breathable socks.
The fit and size are spot on.

I’ve not worn a T in my life that works like the IO. From Exmouth to Adelaide this T worked as described by the company

Great for a cold weekend away (at Wonderland), or smart to wear at work with a Pinnacle Top. Such good quality, I bought 2 if each. The colour has not faded after 3 years wear.

Highly recommended. Non-slip, snug, warm, comfortable and I love the Peaks & Trails logo!

Warm, snug, great colour

The only socks I wear for work, they feel great and never smell.

Very comfortable , great length , fantastic for travel, would recommend, great quality

They are great, warm, and comfortable even while running.

Good fit good comfort

Looks and feels great. Has kept me warm under my jacket in Boston. My second one of these and love it

Comfort and smart enough to wear out.

Best and most comfortable merino clothing for the UK and Canada winter. A must buy is the base layers. Tops and leggings. Very happy with my purchase.
Easy to care.
Can't wait to use my gear for next trip to Finland 2025.
