The Base Layer Edit
We asked: How can something this simple feel this refined?
For most people, a base layer is just a base layer. For us, it’s a design challenge — to perfect the foundation piece. Every seam, stitch, and fiber is considered.
Crafted from ultra-fine Australian Merino, it delivers exceptional softness, breathability, and durability — without sacrificing simplicity.
We believe true performance doesn’t have to be loud. It’s felt — in comfort that lasts, in details you don’t have to think about, and in the confidence of craftsmanship done right.
