T4 WerkBib

The T4 WerkBib is TRUEWERK’s warmest WerkBib, built for extreme cold without giving up mobility. The four-way stretch ripstop shell combines windproof protection and a C0 DWR finish with full insulation for long days in freezing conditions. Integrated AirWerk Knee Pads add cushioning for ground-level work, while full-length side zips make dressing, venting, and access to pant pockets easier. A relaxed fit leaves room for the layers you need underneath.
