Bisley Cooler Weather Range

Insulation type matters more than thickness. Puffer and quilted garments give the most warmth for their weight and pack down when you do not need them. Sherpa and fleece linings are warmer against the skin and more comfortable for all-day wear but bulkier.

For sustained cold, layering beats one heavy coat: a fleece under a wind and water resistant outer traps more air than a single garment of the same thickness, and lets you shed a layer when you start working hard.

Freezer work needs garments built for it rather than heavy outdoor gear. Look for freezer-rated jackets and coveralls, which are insulated for sustained sub-zero exposure rather than for a cold morning.

The distinction matters because a shell that handles rain is not the same garment as one that handles minus eighteen, and the two are easy to confuse from a photo. Check the lining, not the outer.

Yes, and it is worth checking the class rather than the colour. A hi vis jacket worn over the top becomes your outermost garment, so it is the one that has to meet the site's visibility requirement — a compliant shirt underneath a plain jacket does not count.

Day and night work needs retroreflective tape, not just fluorescent fabric. Confirm the standard on the individual product page against what your site specifies.
