What are the Roc Blanc Pants?

Tried and tested by the professionals, the Roc Blanc Pants are perfect for alpine climbing and ski-touring. They've been developed over the years for optimum mountain performance and are made with reliable Gore-Tex® Pro for maximum protection against the elements.

What are they made of?

These trousers comprise Gore-Tex® Pro 3L with a woven ripstop backer, polyamide membrane and Cordura® Dyneema® blend reinforcements. The materials are bluesign® approved, and Oeko-Tex certified, ensuring they're much more planet friendly than conventional technical pants.

Gore-Tex® Pro 3L is a three-layer fabric that provides maximum waterproof protection, with the classic Gore-Tex® Guaranteed to keep you dry™ promise. Whilst fully protective, it's highly breathable to encourage optimum temperature regulation and less sweat accumulation overall, and it doesn't even stop there! Gore-Tex® Pro is completely windproof, protecting you from harsh gusts on exposed routes, and rugged enough to take on extreme environments.

The cut-proof blend of Cordura® and Dyneema® is extremely durable and helps to resist tears from rough surfaces, jagged rocks and contact with crampons, perfect for reinforcing these already hardwearing bum-clingers.

The main materials are treated with PFOA-free durable water repellent for reinforced weather protection, and the ripstop backer is solution-dyed, which is much kinder to the environment.

What are their features?

These trousers have no top stitches to minimise bulk and reduce the risk of seams snagging in demanding terrain.

They have a detachable bib and suspenders for those who prefer extra security and coverage or are exploring more extreme environments.

For storage, three zipped pockets give you plenty of options to tuck away small belongings that you want to keep close-by, such as a GPS device or energy gels. Alternatively, you could clip items onto the belt loops with carabiners for easy access.

At the sides of the legs, 3/4 length, two-way zips are great for ventilation if you need to quickly dump some heat before you carry on with your route.

Articulated knees give you better freedom of movement for steep, technical ascents, and lower leg adjustments allow you to adapt the fit over chunky mountain boots.

Finally, internal snow gaiters help to keep the white stuff on the outside to maximise warmth and improve protection in all conditions.

  • Strong, soft nylon 70D face fabric
  • No top stitches
  • Three zipped pockets
  • 3/4 length, two-way side zips
  • Articulated knees

For best performance:

With any new waterproof, we advise you to wash the product with the appropriate tech wash and reapply a fresh DWR to activate the technology and achieve the best performance from day one.

How does waterproof technology work?

Modern waterproof technology often uses a waterproof membrane sandwiched between layers of fabric and a DWR (Durable Water Repellent) on the outer material.

What is 'wetting out', and how does it affect my waterproof?

DWRs commonly get worn down from contact, whether with your backpack or your fingertips. When the DWR wears down, your waterproof product may begin to 'wet out', meaning the water stops beading off the surface and starts to soak in instead.

While the waterproof membrane will prevent the jacket from leaking or water from getting inside, when your jacket wets out, moisture (from sweat or condensation) can build up on the interior, causing it to feel moist.

There's a common misconception that, when this happens, the product is faulty because people believe the waterproof membrane is leaking. However, this is most likely not the case; you simply need to clean your jacket and reapply the DWR.

The easiest way to spot when this is happening is to see if water beads off the material's surface or soaks in.

PFC/PFAS usage in modern waterproof and DWR technology

Most modern DWR technology avoids the use of PFCs/PFAS chemicals.

PFC-free means perfluorinated chemical-free. Companies such as Gore-Tex® are also beginning to eliminate these harmful chemicals in their waterproof membranes with technology like Gore-Tex® ePE.

What are PFC/PFAS chemicals?

Perfluorinated chemicals (PFCs) are also known as forever chemicals and cause environmental harm, similar to PFAS.

PFAS means per- or poly-fluorinated alkyl; these are a group of industrial chemicals that also cause detrimental harm to the environment, often through product and garment manufacture.

These chemicals can't break down, so once they reach nature (usually via factory water waste), they stay in the ecosystem and contaminate living organisms, working their way up the food chain. PFAS and PFCs are suspected carcinogens and have been known to affect mammal reproduction and hormone production. Therefore, many leading brands in the outdoor industry are now prioritising cutting out the use of these chemicals entirely to contribute to a more responsible manufacturing process.

How to care for a new waterproof product

PFC/PFAS-free waterproof products still perform effectively. However, they will require more frequent care (washing and reapplying a DWR) to ensure consistency.
