SJ TEX MEMBRANE TECHNOLOGY Advanced waterproof & breathable protection SJ Tex is the waterproof and breathable membrane technology behind the all-weather reliability of the Safety Jogger Adventure collection. It delivers reliable waterproofness without compromising breathability - keeping your feet dry, comfortable and fresh, whatever the weather throws your way.

How it works

At the heart of SJ Tex lies a microporous membrane that is engineered for unpredictable weather conditions. The membrane is composed of millions of microscopic pores that are:

  • Smaller than water droplets, preventing external moisture from entering.
  • Large enough to allow water vapour to escape, allowing your feet to breathe.

This way, SJ Tex technology ensures:

  • Waterproof protection from the outside
  • Efficient moisture management from the inside

The membrane is applied to a high-performance lining and protected by outer textile, forming a durable barrier that supports breathability and long-term performance.
