Unmatched Weather Protection
Made with a 100% polyester outer in a hi-visibility yellow and black color-block design, this jacket ensures that you stand out in low light conditions while offering high performance wearability. The reverse mounted 3# nylon waterproof zippers with storm flaps do not let water trickle in, keeping you dry no matter what the weather is doing. Inside, a graphene composite lining improves both thermal regulation and the overall wear of the jacket ensuring that you stay warm and comfortable in extreme conditions.

Advanced Technical Features
The Class 4 Waterproof Jacket is a step above the competition with its advanced climate control system. 120g needle-punched fiberfill with 50% white duck down insulation warms you without weighing you down. A 100% nylon moisture-wicking lining works with the directional airflow vents to maximize breathability so that you can maintain the perfect microclimate throughout your adventure.

Adjustable 3cm elasticized cuffs with thumb loops keep the cold air out; allow flexibility.

2.5cm D-rings for attaching gear; 2cm pig nose buckles on the removable snow skirt offer an additional layer of weather protection.
This jacket is designed for serious expeditions. Rather than just keeping you safe from the weather, it works to make your performance better. Elastic drawcords at both the hem and hood allow for a fit that can be made personal, while reflective 0.6cm sylight piping on important seams makes you more visible when exploring in the dark — safer! Also, 4cm emergency pull tabs on all zippers for quick access when every second counts; 2cm×8cm Velcro closures on the jacket are easy to adjust in a glove-friendly way — you can make the fit better without taking off your gloves in cold weather.

Professional Endurance Certified
This Class 4 Waterproof Jacket has undergone serious tests to validate performance at the highest levels:

  • It is certified for 15,000mm water column pressure, ensuring adequate waterproof protection.
  • It can work within a temperature range of -30°C to 15°C, thus adaptable to different conditions.
  • It can last for 50+ wash cycles without losing its protective qualities.
  • It complies with abrasion resistance standards of MIL-STD-810G; easily survives in the toughest conditions

Versatility for Every Adventure
This jacket isn’t made just for extreme outdoor conditions—it’s made for your lifestyle. Whether you’re Himalayan trekking or just moving through a winter cityscape, this jacket will be by your side through all seasons. The color-block design ensures visibility at all times, while the five-point zipper system (with 5# resin and invisible zippers) offers very easy access to your valuables. The removable 3cm elastic waistband facilitates layering according to the conditions, and snap buttons give secondary secure closures.
