What is the Roc Blanc Jacket?

The Roc Blanc is a minimal alpinist jacket designed for gnarly mountain adventures, whether exploring the Alps or ski-touring with friends. It's lightweight, low bulk and is made from Gore-Tex® Pro to provide reliable waterproof protection and optimum breathability in any conditions.

What is it made of?

This jacket comprises Gore-Tex® Pro 3L with a woven ripstop backer for reinforcement and polyamide membrane. The materials are bluesign® approved, and Oeko-Tex certified, ensuring they're much more planet friendly than conventional shell jackets.

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

What are the features?

The Roc Blanc has a helmet compatible hood that is fully adjustable, allowing you to optimise the fit according to your layering system and whether you're wearing your hard hat. You can adjust it with the front puller separated from the release pull, allowing you to pull it tighter with just one hand. The hood is peaked just above the forehead with metal thread and sheet adhesive for reinforced weather protection.

A water repellent zipper fastening at the front of the jacket uses a two-way YKK® Vislon zip and has a storm flap behind to help keep the weather out further. The two-way zip is perfect for harness compatibility. It allows you to unzip the bottom half of the jacket for harness access without entirely undoing the fastening. Alternatively, it's handy if you need to quickly dump some heat but don't want to take the jacket off and expose yourself to the elements.

There's also tilted front ventilation designed for better accessibility and efficient performance even when carrying a backpack, so you won't have to worry about your straps hindering their performance.

The two chest pockets use the same YKK® Vislon and are perfect for stowing essentials like a GPS device or energy gels. Alternatively, there are two inner pockets if you want to keep belongings more secure - one smaller for valuables and a larger pocket for bulky items like maps.

The sleeves are articulated around the elbows to improve freedom of movement. On the lower left sleeve, there's a handy ski-pass pocket with a zipper to give you quick, easy access if you're heading onto the slopes. Cuffs are also adjustable, allowing you to optimise the fit to your layering system or if you're wearing gloves.

Finally, at the hem, there's another single-handed adjuster if you want to pull in the hem and help retain heat while keeping the weather out.

Features:

  • Fully adjustable hood, to use with or without helmet
  • Hood peak reinforced with sheet adhesive and metal-thread
  • Water repellent YKK® Vislon front zipper with inner storm flap
  • Two-way opening for harness compatibility and ventilation
  • Two chest pockets with sturdy YKK® water repellent Vislon zippers
  • One ski pass pocket at lower sleeve
  • Tilted front ventilation for better accessibility and performance when carrying backpack
  • Two inner pockets, one for valuables and one for bulk storage
  • Sleeves with articulated elbows and adjustable cuffs
  • Drawcord at hem
  • Single hand draw cords for all adjustments
  • Front hood adjustment puller separated from release for easier operation

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.
