Extremities Technology Explained

Next-generation performance. Built from the fabric up.

Extremities has spent decades pushing the limits of glove, hat, and accessory technology. From eco-conscious materials to specialist membranes that keep you warm, dry, and visible — every fabric in our range has a purpose.

Here’s what each Extremities fabric tech means for real-world use:

X-Therm

Maximum warmth with minimum bulk.

X-Therm is an all-season thermal fabric engineered for warmth, stretch, and breathability. The dual-layer fabric pairs a tough outer with an ultra-soft fleece lining next to the skin.

  • High warmth-to-weight ratio
  • 4-way stretch for comfort
  • Smooth outer is abrasion-resistant

X-Dry

Waterproof, breathable, and heat-retentive.

X-Dry is our core waterproof technology. It features a water-resistant outer shell and a breathable inner membrane that lets vapour escape while keeping water out.
helping you stay dry and warm in wet conditions.

  • Waterproof & breathable membrane
  • Blocks external moisture
  • Retains warmth in cold, wet weather

X-Dry Stretch

All the benefits of X-Dry — with added freedom.

X-Dry Stretch uses the same waterproof membrane, but with a flexible outer shell. It delivers the same protection while improving movement and dexterity — ideal for active pursuits or form-fitting gloves.

  • Stretch shell with waterproof membrane
  • Great for technical gloves or high-output use
  • Retains heat with added flexibility
