The landscape of high-performance ski apparel is undergoing a significant shift as Halfdays, a Denver-based, women-owned outerwear company, announces the launch of its inaugural Gore-Tex collection. This partnership marks a milestone in the outdoor industry, as Halfdays becomes the first women-only ski brand to collaborate with W. L. Gore & Associates, the producers of the legendary waterproof and breathable membrane. The move signals a strategic expansion for both companies: for Halfdays, a leap into the elite "technical" tier of mountain gear, and for Gore-Tex, a concerted effort to better serve a female demographic that has historically been secondary in technical product development.
The Evolution of a Strategic Partnership
The collaboration between the boutique Denver brand and the global materials giant was several years in the making. The genesis of the partnership dates back to 2020, shortly after Halfdays was founded with the mission of disrupting the "shrink it and pink it" mentality—a long-standing industry practice where women’s gear was simply a downsized, aesthetically altered version of men’s products.
According to industry reports, the connection was facilitated by a product executive at The North Face who recognized the potential of Halfdays’ design philosophy. By 2022, W. L. Gore & Associates officially agreed to the partnership, initiating a multi-year development and testing phase. This move was described by Gore-Tex Global Account Manager Doug Graham as a necessary step for the company, acknowledging that while Gore had attempted to capture the women’s market for over a decade, previous efforts had lacked the specific design nuances required to truly resonate with female athletes.
The culmination of this effort is the Fall 2026 launch of the "Betty" and "Genevieve" lines. The latter is named in honor of Genevieve “Vieve” Gore, the co-founder of W. L. Gore & Associates, who was known for personally field-testing early prototypes during hiking and camping expeditions.
Rigorous Laboratory Testing at the Elkton Facility
Before any garment can carry the Gore-Tex "Guaranteed to Keep You Dry" hangtag, it must undergo a series of exhaustive tests at the W. L. Gore & Associates factory in Elkton, Maryland. The facility is home to advanced environmental chambers designed to simulate the world’s most inhospitable climates.
The centerpiece of this testing is the "Rain Room," a glass-walled enclosure where overhead nozzles simulate a hurricane-level downpour. Garments are subjected to water falling from 30-foot ceilings at speeds of approximately 20 mph. During the development of the Halfdays Betty jacket and bibs, prototypes were placed in this chamber to ensure that even under sustained, high-pressure moisture exposure, the internal environment of the suit remained dry and the fabric maintained its breathability.
Beyond moisture resistance, the gear was subjected to mechanical stress tests. Using devices that resemble medieval weaponry—such as rotating arms fitted with metal "morning star" balls—technicians abraded and pummeled the fabric to simulate years of mountain wear in a matter of hours. These tests evaluate the durability of the outer face fabric and the integrity of the Gore-Tex membrane under extreme physical duress.
Technical Specifications and Comparative Analysis
The introduction of Gore-Tex technology represents a significant technical upgrade for Halfdays. To understand the shift, industry analysts point to the comparison between the new Betty jacket and the brand’s previous flagship shell, the Lawrence jacket.
- Waterproof Ratings: While the Lawrence jacket features a 20,000mm waterproof rating—considered high by industry standards—the new Betty Gore-Tex 3L shell boasts a 28,000mm rating. This increase allows the garment to withstand significantly higher water pressure, essential for skiing in heavy, wet snow or prolonged storms.
- Breathability and Membrane Technology: The Gore-Tex collection utilizes a three-layer (3L) construction. This involves a high-performance membrane bonded between a robust outer shell and a breathable inner lining. The membrane contains billions of microscopic pores that are 20,000 times smaller than a water droplet but 700 times larger than a water vapor molecule, allowing sweat to escape while blocking external moisture.
- Construction and Weight: Despite the increased technicality, the Betty kit is designed to remain lightweight. The use of specialized seam-taping and articulated patterning ensures that the "stiff" feel often associated with high-waterproof shells is minimized, allowing for a range of motion specifically tailored to female anatomy.
Field Performance: From Maryland to the Chilean Andes
Validation of the laboratory results took place in the Southern Hemisphere, where the gear was tested in the high-altitude environment of Valle Nevado, Chile. Field testing is a critical component of the Gore-Tex certification process, ensuring that the ergonomics of a design match its laboratory-proven durability.
During testing in the Andes, the Betty kit was exposed to wind gusts exceeding 60 mph. Reports from the field indicated that the wind-blocking capabilities of the 3L Gore-Tex fabric were absolute, with no air penetration through the seams or zippered openings. The breathability was also put to the test during physical exertion; testers noted that the "sticky" or "plastic" feeling common in lower-tier waterproof gear was absent, even when adjusting equipment or navigating surface lifts.
However, the field tests also highlighted areas for continued refinement. While the Betty jacket’s pocket placement—designed to accommodate phones, passes, and accessories without adding bulk—received high marks, the sizing of the bibs presented a challenge for shorter athletes. At launch, the Gore-Tex pants are offered in a single inseam length. Halfdays co-founder Ariana Ferwerda has addressed this, stating that the brand intends to expand the Gore-Tex line to include short and tall lengths in future iterations, maintaining their commitment to inclusive sizing.
Design Philosophy: Beyond "Shrink It and Pink It"
The Halfdays approach is rooted in the "women first" design philosophy. Historically, the outdoor industry has struggled to move past gendered aesthetics toward gendered functionality. Halfdays’ entry into the technical "freeride" space aims to bridge this gap.
Key design elements of the Betty and Genevieve kits include:
- Anatomical Pocket Placement: Pockets are positioned to avoid interference with a woman’s natural movement and to prevent bulkiness over the chest and hips.
- Integrated Safety Features: The inclusion of a "phone leash" in the chest pocket and built-in goggle wipes addresses specific user needs discovered through community feedback.
- Tailored Silhouette: Unlike the boxy, oversized fits common in unisex or male-centric freeride gear, the Halfdays collection offers a more fitted, feminine silhouette that does not sacrifice the internal volume needed for layering.
Market Implications and Industry Reaction
The partnership is viewed by market analysts as a savvy move for both entities. For Halfdays, the $645 price point for the Betty jacket and $495 for the bibs places them in direct competition with established giants like Arc’teryx, Patagonia, and Helly Hansen. The Gore-Tex branding provides the "technical credibility" necessary to justify these premium prices to serious skiers.
For W. L. Gore & Associates, the collaboration is a response to the growing economic power of the female outdoor consumer. According to data from the Outdoor Industry Association, women’s participation in high-intensity winter sports has seen steady growth over the last decade, yet the availability of top-tier technical gear specifically designed for women has not always kept pace. By partnering with a "cult status" brand like Halfdays, Gore-Tex gains access to a younger, fashion-conscious, yet performance-oriented demographic.
"We knew we weren’t doing it right," Doug Graham of Gore-Tex admitted regarding their previous attempts to capture the women’s market. This admission underscores a broader trend in the industry where legacy manufacturers are increasingly looking to specialized, demographic-focused brands to provide design insights that larger corporations may overlook.

Broader Impact and Future Outlook
The success of the Halfdays Gore-Tex line could serve as a blueprint for other specialized outdoor brands. It demonstrates that smaller, mission-driven companies can successfully navigate the rigorous certification processes of global technical partners.
As the 2026-2027 ski season approaches, the industry will be watching closely to see how the Betty and Genevieve kits perform over a full season of use. While initial tests in Chile and the Maryland rain room have been positive, the ultimate test will be the "deep winter" conditions of the Northern Hemisphere—sustained sub-zero temperatures, heavy Sierra cement, and the abrasive nature of backcountry touring.
Halfdays has indicated that this is only the beginning of their technical evolution. With plans to expand inseam options and potentially introduce more Gore-Tex integrated accessories, the brand is positioning itself as a permanent fixture in the high-performance market. For the female skier who has long sought a balance between high-fashion aesthetics and "expedition-grade" protection, this partnership offers a long-awaited solution. The collaboration effectively bridges the gap between the runway and the peak, proving that technical gear does not have to be a compromise on form or function.
