Dynafit Unisex Alpine Waterproof 2.5L Overpants Black

What are the Alpine Waterproof 2.5L Overpants?

Good question! They're unisex waterproof shell pants designed for trail running and fast-paced mountain activity in wet weather. The Alpine WP Overpants are incredibly lightweight, durable and breathable to help you feel and perform your best throughout your session.

What are they made of?

These pants comprise bluesign® approved Dyna-Shell™ fabric with a PU membrane and nylon outer layer. The material is light yet highly durable to withstand a beating from regular activity in rugged terrain and, of course, is totally waterproof. It can also provide excellent breathability and is fully windproof, so you won't have to worry about checking the forecast.

The material's outer surface is treated to encourage water to bead off instead of soaking in, whilst allowing vapour from the inside (such as sweat) to escape from within.

Dynafit has also added polyester inserts that allow more stretch for steep ascents and moving through technical, uneven terrain.

What are their features?

These pants are versatile enough for pre-shift jogs around town or morning walks with the dog, making them quite the investment for your wardrobe. The lightness of the material makes these pants super packable, so you could even pop them in a daypack or kit bag in case of emergency if the weather is looking unpredictable.

Taped seams enhance the waterproofness of the trousers by blocking rainwater from sneaking in through the stitching.

An elasticated waist makes them easy to get on and off and much more comfortable around the midsection. The waistband can stretch with you as you move instead of being fixed and feeling restrictive for intense activity.

Articulated knees give you better freedom of movement around the joints. The side zip makes these pants easy to slip on over other layers or hiking boots if you get caught in a sudden downpour.

Wave goodbye to soggy socks - elasticated hems cinch the fabric around your ankles when wearing running shoes, keeping the weather out. It also allows you to fit boots underneath for hill walking and hiking.

Finally, these trousers are finished with reflective detailing to give you extra visibility if you're out after hours.

  • Taped Seams
  • Reflectors

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.
