It’s been two years since Gore introduced the retirement of the Gore-Tex Shakedry expertise. It was forward of a ban on environmentally detrimental PFAS (polyfluoroalkyl) material that rippled out, state by state, from the USA and can quickly be adopted by the European Union.
The shockwaves have been felt all through the biking business ever since because it wasn’t simply the long-lasting Shakedry jacket that had included the chemical substances. Nearly all of the materials used to assemble the finest waterproof biking jackets use these chemical substances. Manufacturers have been going to have to begin once more.
The undercurrent all through this era of change has been the worry that every one our wet-weather gear is about to get rather a lot worse at holding us dry.
We caught up with a variety of cyclewear manufacturers to listen to how they’ve tailored and overcome the problem of going PFAS-free and what it means to your favorite biking rain jacket.

Castelli
Castelli had been hit laborious by the PFAS ban, with its iconic Gabba one of many first to really feel the aftermath of the USA ban. Castelli rapidly pivoted, with the reworked Gabba R.
Castelli World Model Supervisor, and one-half inventor of the unique Gabba, Steve Smith, defined: “For those who had requested me [about the legislation] even six months in the past I might have been actually adverse.
“The model explored a variety of “non-permeable membranes”, he mentioned, however these merely left the rider moist on the within.

“Plenty of material suppliers have been taking place this route, everybody was fascinated with waterproofing however not breathability,” he confesses, confirming that this was the trigger for dissolving the long-time partnership with Gore-Tex materials.
“For some purpose, the business purchased right into a considerably ridiculous measure of what might be outlined as waterproof,” says Smith, explaining that it is traditionally been examined to 10,000mm of water column, or the stress of 10m of water urgent down on you. “For those who’ve ever dived to 10m depth what that form of stress seems like”, he says, including that the usual was made in order that you can sit together with your full physique weight in a puddle of water.
“In biking, we don’t actually have this degree of stress pushing towards the water,” Smith tells me, clarifying {that a} regular rainfall is equal to round 800mm water column, add the pace of the rider and, based on Smith, a bike owner will keep successfully waterproof at even 2000mm water column.
“As soon as once more we now have a ‘customary’ that’s made to promote over-engineered materials that transcend what we actually want, and sacrifices breathability within the course of,” states Smith, earlier than he confirms that Castelli’s newer Gabba R merchandise have been examined to 5000mm of water column.
“We nonetheless have waterproof shells” he explains, earlier than concluding that waterproofing has not been taken off the desk, however you will be dryer and extra comfy all day in one thing way more breathable.

The material of most waterproof jackets is a sandwich of three layers: an outer with a sturdy water-repellent (DWR) remedy that visibly beads water as it’s repelled, a breathable waterproof membrane within the center and a softer knit subsequent to the pores and skin. Gore-Tex Shakedry eradicated the outer layer, exposing the PFAS-containing ePTFE membrane, and did not want a DWR coating. That is what made it so gentle, waterproof and breathable — and handy because it by no means wanted reproofing. The problem now’s to recreate this with out utilizing PFAS chemical substances.
As a model that hasn’t used Gore-Tex materials since 2017, selecting as an alternative to work with material home Polartec, Santini says it was able to section out PFAS material a lot prior to some biking clothes manufacturers.
“Cloth has to perform tougher because the particular person perspires, and a bike owner will get to that time a lot faster than somebody going for a stroll in a forest,” says Santini Inventive Director, Fergus Niland.
“The crucial metric [in cycling] is the air trade, to cease you wetting out from the within out” including that it is this inner build-up of sweat that’s chargeable for getting chilly on a moist experience,” he provides, explaining the challenges behind making a breathable waterproof membrane.
Made with Bio-nylon, which Polartec says comprises 48 p.c plant-based content material, the Polartec Energy Defend Professional material that Santini makes use of for a lot of of its prime water-repellent jackets, whereas PFAS-free, reverts to the three-layer membrane system, which Niland confirms would require PFAS-free DWR re-treating over time.
Final week Santini launched its Magic rainproof jacket, which is among the first clothes to make use of the brand new Polartec Energy Defend RPM material, a really light-weight, elastic, packable and extremely breathable materials. The material is made out of eco-friendly, recycled polyester.

What are PFAS?

Polyfluoroalkyl substances (PFAS), often known as ‘endlessly chemical substances’, aren’t simply utilized in biking package. Present in numerous foams, pacemakers, non-stick pans and 1000’s of on a regular basis merchandise, PFAS are proof against warmth, oil, grease and, crucially for biking, water. The issue is that they don’t break down, discovering their means into water methods, soil, and us. The chemical substances have been linked by scientists, together with the United States Surroundings Safety Company and European Surroundings Company, to critical well being and environmental issues.
An exception to PFAS-free pivoting is Assos. The model’s Senior Supervisor of Improvement, Luca Zanasca, and Textile Knowledgeable, Claudio Lanfrancon, confirmed that it’s only beginning to take away the material from its collections, with summer time 2025 seeing the primary modifications, and the model hoping to be PFAS-free by autumn/winter 2025/ 26.
Asking the pair extra in regards to the anticipated efficiency of those new incoming materials, Lanfrancon explains that “there is not going to be a really perceptible distinction for the rider,” including that customers may discover a bit much less water resistance.
“Now we have massive modifications deliberate for 25/26,” Zanasca lets slip. “Winter clothes efficiency will stay the identical, however equipment will keep away from waterproofing.”
Quizzing Zanasca extra, he tells me that a number of the main target will probably be on the model’s best-selling Mille GTS [Wasserschnause] Rain Jacket S11. “A brand new model will enhance on the final iteration, with related waterproofing, however improved breathability,” he says, earlier than concluding that “it’s not only a case of creating a rain jacket, its software and match are simply as necessary”.

Altura
Serving the UK riders solely, the British model Altura shouldn’t be on the behest of any US or EU PFAS laws. That mentioned, Head of Personal Model, Ian Younger was eager to press that Altura continues to be working to take away the endlessly chemical from its materials, stating: “It’s the proper factor to do, particularly for a model working straight with the outside”.
Younger says that the well-known Altura Evening Imaginative and prescient vary is nearly PFAS-free, however legacy inventory continues to be in circulation.
Younger confirmed that when evaluating the older PFAS-based material on the Evening Imaginative and prescient vary, to the brand new model, the water-proofing gained’t final as lengthy.
“New materials simply require you to clean and retreat extra usually. It’s not going to be s**t out the field. You’ll simply need to take care of them a bit extra,” clarifies Younger.
“If something, new materials are going to be higher” he provides optimistically. “They are going to be extra sturdy and sustainable than the older Gore-Tex Shakedry [ePFE), which had a lot of usage restrictions, such as the risk of damage when using a rucksack or riding off-road.”

Rab (Equip Deutschland GmbH group) has very much led the charge on PFAS-Free fabrics, as early adopters of the Gore ePE (PFAS-Free) fabrics.
Cycling Weekly has already covered the brand’s move to providing Material Facts transparent data sheets for every piece of RAB apparel, and its road map to becoming completely PFAS-free can be found on the Rab website.
Equip Deutschland GmbH PR and Communications Manager for Europe, Sarah Kampf, informed me that the brand is now focusing on educating consumers who have “become very used to the performance of older PFAS waterproof fabric”.
“The newer solutions perform differently and have a different look and feel when wet,” admits Kampf, adding that fabrics now have to be treated and cared for differently after purchase, which she believes is the biggest challenge going forward.

Award-winning independent outdoor brand AlpKit has gained a loyal following of UK customers who buy into the brand’s ethical ethos.
Head of Clothing Ronnie Legg told me that the brand started moving away from PFAS-based DWRs more than five years ago, although, surprisingly the brand isn’t yet PFAS-free.
Legg says the challenges are often due to limits with supply-chain options on small amounts of fabric where sources of PFAS can cross-contaminate garments, such as the oil in sewing machines.
According to Legg, PFAS-free DWR fabrics are an imperfect solution. “It’s not that it doesn’t repel water as well [compared to PFAS), but that it doesn’t repel oil,” he says, explaining that dirt and contaminates can prevent the water-repellent effect, and will happen much quicker with PFAS-free DWR compared to the older formulations.
Legg reiterates the importance of customers doing more aftercare, washing, and re-proofing, which adding to customer demands for lighter-weight fabrics with higher levels of breathability, will mean a compromise on durability

Rapha
With Gore as a main fabric partner, Rapha was in a similar boat to Castelli when having to re-consider life without old PFAS-based fabrics. However, Rapha remained loyal to the brand and has just announced a new Rapha Gore-Text rain jacket.
Using the same new ePTE [PFAS-free] Gore-Tex material because the Gore Put on SpinShift rain jacket (see under), the rain jacket was launched amidst a lot fanfare and aplomb, boasting to be completely windproof, reliably breathable and durably waterproof.
Staking declare to the primary efficiency put on use of the material, Rapha states that the three-layer membrane is as slimline as potential and assured to maintain you dry.
What shouldn’t be assured, nevertheless, is it truly being PFAS-free, which is fascinating small print studying hidden beneath the massive headlines.

Gorewear
As a cloth home and clothes model, Gore and Gorewear have been performing a double act on the subject of shifting away from endlessly chemical substances in its ranges, engineering a completely new material, alongside designing it into rainwear. Having quietly introduced the sluggish retirement of its groundbreaking Shakedry jacket and material two years in the past, Gore had in truth already been working considerably longer on a substitute Gore-Tex ePE materials.
Launched again in 2021, the expanded PFAS-free Polyethylene (ePE) material is described by Product Specialist at GoreWare Christian Mayer as tremendous skinny and light-weight, whereas nonetheless able to offering the identical degree of “sturdiness and sturdy waterproofness”.
The SpinShift GTX jacket, constructed utilizing the brand new material, was launched earlier this yr, with the model utilizing the chance to extend the usage of sustainable textiles by incorporating a recycled face textile and a recycled and dope-dyed backer.
Michael Jean-Jacques Manufacturing Line Supervisor Gorewear explains the challenges of making certain a sports-specific match and minimising the majority created from waterproof taped seams. Regardless of shifting to a three-layer membrane, Gorewear tells me that when evaluating its C5 GTX SD 1985 jacket and the brand new Spinshift GTX Jacket there’s solely a 37g improve (each dimension Massive).
What does this imply for me?
It does seem that the outdated days of by no means ending water beading have come to an finish, and, as many manufacturers have put it, there’s now an onus on us customers to play our half in adapting to the ‘new regular’ on the subject of expectations of lifetime rainwear efficiency.
The large take-home message for riders is that aftercare will probably be paramount to the efficiency longevity of your future, or current, PFAS-free biking rain jacket.
We have tried to demystify the right way to re-waterproof your biking gear utilizing (environmentally pleasant) DWR therapies, which ought to assist take away some apprehension from sticking a, often very costly, jacket within the washer.
