The Portwest S766 is a hi-vis outer jacket with a zip-out fleece inner, built for outdoor work in cold and wet weather. Wear the pieces together or apart in five ways, so one jacket covers a wide range of conditions through the year.
The outer jacket has a waterproof shell with taped seams, reflective tape and a hood that packs away when not needed. The inner jacket has detachable fluorescent fleece sleeves and dark contrast panels that help hide dirt in the areas that pick up the most grime.

Five ways to wear
Zip the fleece inner into the outer jacket for the most warmth in cold, wet weather. Wear the waterproof outer on its own when it is mild but wet, or the fleece inner on its own in dry conditions. Remove the fleece sleeves to turn the inner into a bodywarmer, worn alone or zipped into the outer for extra core warmth with less bulk at the arms.
Care
- Machine wash at 40°C on a gentle cycle
- Do not bleach

- Drip dry
- Do not iron
- Do not dry clean
- Certified for up to 50 washes
