Favorite Base layer

a year ago
I wear this for running as a stand alone layer and as a base layer. I'm 5'9" 150lbs and went with a medium for a looser fit. No odor issues after several uses. I would love to see a lighter white/beige/natural color.

Ionia Merino Wool Shirt LS Men's

Innate performance and natural comfort – the Ionia delivers. Made from Merino wool – a material known for temperature regulation and odour resistance – it’s light, soft, breathable, and responsibly sourced. The construction wraps the wool’s fine-gauge fibres around a nylon core for added durability. The fit is streamlined and comfortable, and the articulated patterning moves with you on hikes, runs, tours, and treks.

Trail

For technical mountain activities, durable and protective designs with a focus on freedom of movement for remote and varied conditions.

Natural fibre

Textiles made from natural fibres provide inherent benefits and next-to-skin comfort.

Synthetic fibre

Engineered materials that offer enhanced properties or performance.
