Our journey began with a singular mission:

craft the ultimate winter gear

We set out to harness the finest fabrics and manufacturing facilities to create the pinnacle of winter sports gear without being constrained by price points set by retailers. Every design decision was solely made around "we only want the best." We were able to create this jacket at a reasonable cost to you by eliminating retailers and retail markups, passing those savings on to you. This is why you can only buy directly from us on our website and our products are not available at any 3rd party retailers or stores.

selecting the right partner


Based out of Japan, Toray International Inc. has a vertically integrated structure that gives them a unique ability to design and produce custom textiles that solve specific real world issues. 3DeFX+® is a garment concept that brings together a unique combination of fabrics, insulation, and sewing technology for elite performance in a wide range of conditions and exertion levels paired with unmatched breathability and durability. This technology enables us to create warm, ultralight, breathable, packable insulation that can be paired with our waterproof, windproof, and breathable hardshell for an extremely versatile winter layering system.

leveraging science for peak performance

next generation insulation

Designed to be worn as a stand-alone jacket or as part of your winter layering system.

Keeping athletes comfortable during cold weather is a challenge. Insulation jackets, while warm, can become stuffy when you start sweating during exercise. Toray has innovated the entire insulation production process to solve this problem, ensuring comfort throughout physical activity. 3DeFX+™ represents a next generation solution, achieved by blending advanced technologies across fibers, insulation, fabric, and stitching.

the arctic fox - inspired by nature


In the unforgiving Arctic environment, where Arctic foxes brave extreme cold, 3DeFX+ found inspiration in their two-layered fur structure. Emulating this natural marvel, 3DeFX+ incorporates 4 types of multi-denier, hollow-core, spiral yarns with a layer of thin yarns close to the body and a layer of thicker yarns towards the exterior. The 3D spiral structure enables a lighter, thinner layer of insulation to capture more insulating air between the fibers, unlike anything else on the market.



The 3D spiral structure of 3DeFX+ enhances its ability to capture and hold air. Air is an excellent insulator, and the trapped air within the insulation acts as a thermal buffer. It can absorb excess heat from the body when you're warm and release it when you're cold, helping to maintain a comfortable temperature. This thermoregulating effect keeps you warm in cold conditions and prevents overheating when you're active, making it an excellent choice for a wide range of outdoor sports and weather conditions.


Refined for Movement

Made to Push the Limits

stretchable & breathable

Innovative materials and design allow 3DeFX+ 4-way stretch without compromising warmth or breathability. The 3D spiral structure enhances this multidirectional stretch, providing 360-degree flexibility without any fiber migration. Unlike typical insulation, 3DeFX+ doesn't require fabric coatings and non-stretch fabrics to prevent insulation migration, allowing for the use of stretch fabrics with significantly higher breathability in both the interior and exterior of the jacket.

the most challenging conditions

built for bad weather

Engineered to endure the most challenging wet conditions while maintaining warmth. Alongside an external DWR coating on the face fabric, a specialized 30% silicon yarn on the insulation's surface repels water droplets, preventing them from permeating the insulation and preserving heat retention. One of the benefits of synthetic insulation is that it can continue to retain heat when wet. However, when other synthetic insulations become saturated their ability to retain heat is significantly reduced.

PREMIUM FEATURE - no ordinary fleece

fleece side panels

Plush Karuishi fleece blends warmth, breathability, and stretch throughout the side panels. Its unique structure allows air circulation, regulating temperature and moisture. This results in greater comfort during activities while maintaining insulation. Additionally, Karuishi fleece boasts exceptional stretch, ensuring freedom of movement.

50% recycled insulation & engineered to last longer

3DeFX+ insulation was able to achieve a recycled rate of fifty percent without compromising existing functionality. The stunner stretch nylon fabric adds enhanced durability for an insulation piece. We design all of our products to be as durable as possible, to meet our performance needs, and are always looking for options that are better for the planet and the wild places we call home.

Gear that endures, like our Legacy collection, is a sustainable choice by eliminating the need for frequent replacements due to compromised performance or overall product durability. Constantly producing more products with short life spans creates excess waste. Anything that can be recycled from non-durable products does still have an environmental effect to make it usable again. Anything that cannot be recycled ends up in a land fill. Creating rugged, high performance, long lasting products is an eco-conscious approach, aligning with our commitment to environmental responsibility.

We envision a circular commerce system that eliminates waste and pollution, giving used clothing a second life. Enter AKOVA RENEWED™️, our gear renewal program. It empowers customers to trade in their used gear, receive a 30% discount off their next purchase, and shop for quality used apparel.


winter layering

We wanted a layering system that was simple, specifically designed for high output winter sports, and versatile for a wide temperature range.

  • Baselayer - Women's LS 1/4 Zip: Graphene fabric technology provides thermoregulating next-to-skin comfort and effectively moves moisture away from the skin keeping you dry and comfortable
  • Midlayer - Legacy Insulator: Warm but extremely breathable synthetic body mapped insulation
  • Outerwear - Legacy Jacket: Rugged and durable protection from wind and rain

Julia has put this three-piece setup to the test in sub-zero conditions to warm spring skiing. These layers excel by efficiently wicking moisture away from your body and out of the system while preserving the ideal amount of warmth.
