For skiers and outdoor enthusiasts, in-motion comfort has become a key focus, with every detail from functional performance to wearing experience shaping product choices. As the layer closest to the body, base layers have evolved beyond basic sweat-wicking and quick-drying functions. Modern users increasingly seek diverse materials, versatile performance, and a high level of daily wearing comfort. Options now range from synthetic fibers (polyester, spandex, nylon) known for sweat-wicking, quick-drying and durability, to Merino wool with balanced warmth, breathability and natural odor resistance, as well as Merino wool blends that combine the strengths of natural and synthetic fibers.
Cashmere, a rare natural fiber, offers notable warmth, moisture absorption and softness due to its unique physical properties. Integrating cashmere into ski base layers can bring an added level of comfort to outdoor participants. Yet despite its well-regarded qualities in high-end apparel, cashmere remains a less common choice in outdoor performance clothing. This article looks into the properties of cashmere and how Surpine has adapted it for practical outdoor use.
Cashmere Fiber: Characteristics and Practical Challenges for Outdoor Apparel
In high-altitude and cold regions, goats grow a fine undercoat in autumn to withstand low temperatures, which sheds naturally as temperatures rise in spring. This fine undercoat is the source of cashmere, following a natural growth and shedding cycle.
Hollow Fiber Structure: Balanced Warmth and Airflow
Cashmere features a hollow fiber structure that traps stationary air within the fiber, creating a light thermal barrier against cold air. Its thermal retention properties are generally 1.5 to 2 times those of conventional wool. The hollow structure also supports smoother air permeability, helping to reduce stuffiness during activity.
Capillary Effect: Natural Moisture Movement
The scaly, slightly indented surface of cashmere creates small gaps between fibers, forming natural capillary channels. Combined with the fiber’s hydrophilic traits, cashmere can absorb sweat gradually and support moisture movement, helping maintain a more stable skin surface during exercise.
Consistent Fiber Fineness: Softness and Flexibility
Cashmere fibers typically range from 13um to 15.5um in fineness with consistent thickness, contributing to a smooth and soft hand feel. The fiber also has stable crimp properties, offering good flexibility and shape retention under bending, stretching and twisting, supporting unrestricted body movement during sports.
While cashmere provides desirable comfort and thermal traits, it presents several practical challenges when used in outdoor performance apparel.
Challenge 1: Limited Global Supply
Cashmere production is relatively restricted. Each goat yields 50g to 80g of cashmere per year, with a maximum of around 200g of refined dehaired cashmere. Global annual cashmere output stands at roughly 11,000 to 26,000 tons, accounting for approximately 0.2% of total global animal fiber production, making it a scarce natural material.
Challenge 2: Collection and Cost Factors
Cashmere is mainly collected by gentle combing from live goats, a method considered more animal-friendly than traditional shearing. This specialized collection process, paired with its limited supply, contributes to higher material costs and restricted production capacity.
Challenge 3: Durability and Drying Limitations
Cashmere fibers are fine, short (30–45mm) and have lower tensile strength, which adds complexity to spinning and weaving, especially for fine-gauge base layer products. Additionally, cashmere’s high moisture absorption and regain rate result in slower drying speed, which may not fully align with the needs of high-intensity outdoor activities. These factors have limited its wider use in performance outdoor gear.
Surpine PEAKCASH Collection: A Practical Application of Cashmere in Outdoor Apparel
Surpine focuses on improving functional comfort for outdoor participants. For the 2024–25 ski season, the brand launched the PEAKCASH collection of cashmere-blended outdoor functional base layers. Starting from material selection, the brand adjusted processing and blending methods to adapt cashmere to the demands of outdoor sports, exploring new ways to incorporate premium natural fibers into performance apparel.
The PEAKCASH collection combines rare cashmere fiber with fine 15.5um Merino wool yarn and selected functional yarns. This blended construction retains the temperature regulation, moisture absorption and odor-resistant properties of Merino wool, as well as the quick-drying, wear-resistant and far-infrared heating traits of performance yarns. The addition of cashmere also helps improve the overall softness, lightness and thermal comfort of the garments.
Combined with Surpine’s body-mapping design principles, the collection uses targeted zoning to enhance moisture release in high-sweat areas and improve thermal retention in heat-loss zones. This structured approach supports more balanced performance across changing activity levels and environmental conditions, supporting consistent comfort during outdoor movement.
Surpine continues to test and integrate advanced natural and functional fibers for outdoor gear, developing material blends and structural designs that better suit real-world sports scenarios. By refining material combinations and ergonomic design, the brand aims to deliver reliable, performance-focused base layers for outdoor enthusiasts. We look forward to supporting explorers in maintaining steady comfort as they pursue outdoor activities.
