K18 Launches HeatBounce, Haircare's First Intelligent Heat Protectant
K18 just embarked on its biggest launch of the year. The biomimetic hair brand released its HeatBounce conditioning heat protectant on July 23. Powered by proprietary ResiliCore heat-shielding technology, the patented development was inspired by nature's most flexible and heat-resilient protein resilin. The cutting-edge formula was designed to be the first of its subcategory.
'It dynamically activates with heat, reinforcing the inner structure of the hair fiber,' co-founder and CEO Suveen Sahib said exclusively, comparing it to Gore-Tex waterproof fabric. 'It's lightweight, breathable protection from within, unlike the old-school rubberized approach. It's designed to keep hair resilient during styling and long after, when external heat and mechanical exposures can do just as much harm. It's proactive, it's responsive and it's built on years of research into how nature defends itself from heat.'
The Decision To Launch HeatBounce
With only eight original SKUs since launching its groundbreaking $75 Leave-In Molecular Repair Hair Mask in 2020, each K18 release comes with meticulous detail and execution. The current launch follows the March 2025 release of AstroLift Reparative Volume Spray.
'We only launch when we can believe we can truly change the game,' Sahib said. 'Heat protection has stayed stagnant for decades, relying on surface coatings that act like rubber raincoats. They're heavy, temporary and ineffective where damage really starts. Meanwhile, heat styling has evolved, with faster tools, dynamic temperatures and more frequent use. Yet, the tech to protect hair hasn't kept up.'
This is where HeatBounce entered the chat. Calling it the 'first intelligent heat shield for hair,' Sahib went on to stress the importance of treating heat protection with all-day maintenence.
'The biggest misconception in heat care is that protection is a one-and-done event: apply, style, done,' he explained. 'But in reality, heat stress is progressive. It starts in the salon and continues long after the client walks out, especially under environmental heat exposure and our daily styling routines.'
Sahib insists there's no innovation on the market that compares.
'Traditional products protect the outside, and HeatBounce defends from the inside where thermal breakdown starts,' he said. 'ResiliCore activates with heat to reinforce internal bonds and create a resilient, flexible defense network. And unlike traditional coatings, it doesn't break down or build up. It continues protecting through additional exposures such as mechanical and environmental stress.'

Maximizing The Benefits of HeatBounce
The brand will spread education on HeatBounce through its longtime ambassador Devante Turnbull, who has most recently been using K18 products on tour with SZA.
The new formula starts as a lightweight cream, then transforms into a fine mist for even, weightless application. It can be use on damp or dry hair before any kind of heat, blow-drying, flat-ironing, curling or diffusing. It can also double as a shield for daily protection. All K18 products were formulated to work cohesively as a full system, and no matter the launch, the brand will always stick to its pillars.
'Biology knows best,' Sahib said. 'Our work isn't cosmetic, it's molecular. With K18Peptide, we repaired broken keratin chains. With HeatBounce and ResiliCore, we're helping prevent that damage from happening in the first place. For us, this is not a line extension. It's a leap forward, marking a new era in proactive, biotech-powered styling.'

Arc'teryx Partners With Gore-Tex For New Waterproof Membrane
Arc'teryx has partnered with Gore-Tex since 1995. Now, 30 years in, the collaboration has resulted in a new waterproof and breathable membrane that Arc'teryx calls lighter, more durable and more responsive than any before it. The Gore-Tex Pro ePE fabric makes its debut in the Arc'teryx Beta AR jacket, a 25-year-old silhouette that has helped define the Canadian brand. Calling it the toughest and more durable jacket in the Beta family, the redesigned Beta AR features the new Gore-Tex Pro ePE membrane, along with enhanced fabric lamination, new cord locks for increased durability and pack-friendly pockets with easier access. In 2024, Arc'teryx updated its lineup of shells with the Gore-Tex ePE technology, a waterproof membrane free of intentionally added chemicals, and with half the thickness and lighter than previous membranes. In 2025, Arc'teryx shows off its latest collaboration with Gore-Tex, having led the development of the Gore-Tex Pro ePE. The new fabric features a membrane, a backer underneath and a face fabric on the top. Both the ePE and Pro ePE features the same membrane but differ in the backers and face fabrics. 'The next generation Gore-Tex Pro technology is a major leap forward,' Sara Ellis, global Gore-Tex Pro product specialist and materials engineer, tells me. 'It provides the same trusted waterproof, windproof, breathable performance—now lighter, made without intentionally added per- and polyfluorinated substances and utilizing recycled textile content.' Ellis says the new product is a 'milestone in merging pinnacle durability with a lower environmental footprint,' which opens new design possibilities. To make it through the Gore-Tex process, every membrane and laminate was subjected to a bevy of testing. Lab testing included the Gore-Tex Rain Room in the brand's Delaware headquarters. To simulate the harshest conditions, the rain room sends three inches of rain per hour in hurricane-level wind and rain to dump six gallons of rain per minutes for 30 minutes. Only if a design can pass that test is it sent out to the field for real-world testing. Lab testing features plenty of durability tests, including ruggedness testing to check a fabric against rips, tears and abrasions while ensuring it retains its waterproofness. The Martindale machine functions as a key simulator, mimicking abrasions by 'stamping' material repeatedly. The Gore-Tex ePE had to handle 5,000 repetitions, while the new Gore-Tex Pro ePE takes on 20,000 'stamps.' The Beta AR launched in 2000 and has enjoyed eight updates since. In 2004, Arc'teryx reduced the width of the seam tape to 13mm to increase the flexibility and added a drop hem, laminated the internal chest pocket and reinforced the elbow and shoulder areas while dropping the overall weight to 540 grams. In 2007, the brand introduced a Gore-Tex Pro Shell that was lighter with more breathability while streamlining the seams for improved ability to withstand weather. The 2010 update featured more water-tight zipper designs and in 2013 a new lightweight Gore-Tex fabric with a woven nylon backer helped increase durability while reducing weight to 440 grams. The waterproof protection in the zippers and hood improved in 2018, the fabric got an upgrade in 2020 and the brand's StormHood was introduced in 2023. 'Twenty-five years ago, the original Beta AR revolutionized the outdoor industry,' says Tanya Hall, Arc'teryx design expert for advanced concepts. 'Its innovative DropHood, hand pockets and essential pit zippers quickly made it one of the most coveted hardshell—and it was this very DNA that inspired some of the first guide jackets we developed for mountain professionals in the early days.' The 2025 version now features regular, articulated fit to allow for layering, roughly 15 stitches per inch for durability, glove-friendly cuffs to help seal out weather, two zippered hand pockets, a DropHood, a reflector in the hood brim, internal cord locks, pit zippers for temperature regulation and an adjustable hem drawcord. And it all comes with the latest in waterproof breathability from the Arc'teryx Gore-Tex collaboration. The updated Beta AR design saves over 1.5 miles worth of material annually thanks to newly optimized fabric patterns. 'We also,' says Amber Heath, Arc'teryx senior designer for women's hike, 'dedicated significant attention to the precise placement of pit zips and pockets on our women's styles, enhancing both functionality and fit.'
