Men's Tech Prism 1/2 Zip Tee Green

Ronhill Men’s Tech Prism 1/2 Zip Tee

The Tech Prism 1/2 Zip Tee is a thermal running top for cold or cool days, designed to work effectively as a midlayer: over a baselayer, under a jacket or directly against the skin. The “Prism” fabric with its hexagonal grid traps air for insulation without adding unnecessary bulk, so you can move freely during every training session.

At the same time, it manages sweat very effectively: it moves moisture from the inside to the outside to help you stay dry and comfortable, even when the pace increases.

What makes Prism technology stand out

The “hexagonal grid” works as “smart” insulation: it retains warmth when it is windy or cold, while remaining breathable and low-bulk for effective layering. Ronhill also states that denier gradient technology enables faster moisture transfer to the outside.

• Winter running and training in cold or windy conditions
