What is the Taiss HS Hooded Jacket?

It's a versatile performance jacket with a balance of features that make it suitable for all seasons. Whether mountaineering or alpine climbing in the summer, or ice climbing and ski touring in the winter, the Taiss HS will keep you dry and comfortable in variable conditions.

What is it made of?

This jacket comprises Mammut's very own DRYTechnoloy™ Pro made of polyamide to provide lightweight durability. Mammut DRYTechnology™ Pro offers breathable windproof and waterproof protection with a Hydrostatic Head of 27,000mm.

The outer material is treated with a PFC-free DWR (durable water repellent) for reinforced weather resistance.

PFC-free DWR's are a much more sustainable approach to water repellent treatments compared to conventional methods, as they don't use per- or poly-fluorinated chemicals that can damage the environment.

The polyamide membrane is based on natural raw materials, earning its bluesign® approved status that ensures it's safe for consumers, the environment and the workers involved in producing it.

Mammut also works with FairWear to ensure safe, ethical working conditions in their factories, helping to protect workers' rights and being considerate and sustainable with their processes.

Inside, the shell is lined with polyamide elastane mesh that feels smooth next to the skin and offers enhanced freedom of movement.

What are its features?

It has a helmet compatible Single Pull Hood™ that can be adjusted both vertically and horizontally with, yep, you guessed it, a single pull - perfect if you have your hands full with gear or are in the middle of an ascent and need some quick relief from the weather. The hood is also labeled storm-proof, giving you more coverage without impeding peripheral vision, perfect for tackling steep, challenging ascents in harsh conditions.

You can also adjust the hem in a similar fashion, with a one-pull cord. Both the hood and hem have COHAESIVE® stoppers that are easy to use with one hand, chunky gloves or numb fingers.

The fastening at the front uses a two-way water resistant Aquaguard® zipper, ideal for extra ventilation or making a climbing harness more accessible.

The two front pockets are harness- and backpack-compatible, ideal for stowing away snacks and energy gels for a quick on-the-go pick-me-up. Cross-over access makes them easier to get in and out of, and water repellent zippers protect contents inside. There's also an internal zipper pocket for more valuable items like keys, a mobile phone or emergency cash.

Sleeves are preshaped to give you more flexibility and freedom of movement for technical activity and can be adapted using simple hook and loop fasteners. The jacket is built with High Reach Technology™, developed to help prevent the jacket from riding up and exposing skin when you're stretched out, keeping you fully covered from the elements at all times.

X-Vented underarm ventilation with water repellent zippers offers a quick solution to dump heat and balance body temperature. Simply undo the zippers until you've cooled down, and then fasten them back up when you're done.

Features:

  • MAMMUT High Reach Technology™ for unrestricted freedom of movement when climbing
  • MAMMUT Single Pull Hood™: storm-proof, helmet-compatible hood with reinforced peak, can be adjusted both vertically and horizontally with a single pull
  • 2 climbing harness- and backpack-compatible front pockets with cross-over access and water-repellent zippers
  • X-vented underarm ventilation with water-repellent zippers
  • Internal zipper pocket
  • Water resistant Aquaguard 2-way front zipper
  • Pre-shaped sleeves with hook and loop fastener
  • One-hand adjustable drawstring cord with Cohaesive® stoppers for easy adjustment of hem and hood - even when wearing gloves
  • PFC-free DWR treatment

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.
