Waterproof Workwear Shell
RUINIU uses nylon and polyester shell fabrics including Taslan and Ripstop constructions. PU membranes, TPU coatings and DWR finishes can be selected according to waterproof requirements, garment weight and working conditions.
Detachable Workwear Liner
Fleece liners are suited to lighter insulation and frequent indoor-outdoor use. Synthetic padded liners provide more insulation for colder working conditions. Liner zippers and snap connections are developed together with the outer shell.
| Layer Option | Best For | Main Characteristic |
|---|---|---|
| Fleece Liner | Mild winter / indoor-outdoor work | Lightweight warmth |
| Synthetic Insulated Liner | Colder outdoor work | Higher insulation |
| Shell Only | Rainy or windy conditions | Weather protection without added insulation |
