T-OLS 135 is our lightweight, long-sleeved crew neck. It is for you if you want coverage down to your wrists while keeping the airy feel of our 135 fabric. Wear it on its own day to day or as a soft layer beneath a rain jacket or shell on a cool run.

We knit the fabric in Denmark from 100% merino wool. Its thin construction is a deliberate choice, allowing excess heat to escape more easily as you pick up the pace. We prefer pure wool for this model for its comfort and ability to regulate temperature and manage moisture. On cold days, add a short-sleeved T-shirt or a warmer outer layer.

The long sleeves provide coverage without a heavy fabric, but the thin material can develop holes more easily and wear out faster than our thicker fabrics. For a long-sleeved T-shirt with greater durability and more warmth, we recommend T-OLS 220.
