Recommendations from our Unishore Expert

This long-sleeved design is spot-on if you're after all-day comfort with proper arm coverage. The cotton content means the fabric breathes naturally, preventing that clammy feeling even when you're working hard. The reflective striping has been strategically placed across the shoulders and chest, giving you maximum visibility in low-light conditions or busy work environments. The moisture-wicking properties keep sweat at bay, and the neck guard eliminates that annoying rubbing that some hi-vis wear can cause. If you're regularly outdoors, the UV protection works quietly in the background, safeguarding your skin during extended exposure. This T-shirt performs well when paired with hi-vis trousers or layered under a visibility jacket for cooler conditions.
