Cumulus Fastier M’s
339,00 €
Weight: 160 g
Cumulus has redefined the shell jacket market with this year’s most exciting innovation: the Fastier shell jacket. Weighing an astonishingly light 160 grams, this three-layer jacket featuring the premium Pertex Shield membrane is here to shake things up in the world of shell jackets!
For years, the development of ultralight shell jackets has been somewhat uninspired—until now. The Fastier is a true breath of fresh air, combining the durability of a true 3-layer construction with an ultralight design. Crafted with the premium Pertex Shield membrane, it stands out as a pinnacle of performance in shell materials.
When it comes to shell jackets, weight and packability are critical. As they often stay stowed in the backpack, shell jackets need to be as light and compact as possible. At just 160 grams, the Fastier is a true ultralight champion. But don’t let its featherweight fool you—it’s durable thanks to its smart 3-layer construction. The membrane is protected by fabric on both the inner and outer layers, shielding it from the wear and tear of backpack straps and long trail kilometers.
This ingenious combination of an advanced membrane with lightweight inner and outer fabrics is, in our view, the ultimate technical solution. Yet, it’s a rarity in the shell jacket world—making the Fastier the current champion of waterproof breathable jackets.
Cumulus Fastier M’s
The Cumulus Fastier is purpose-built for ultralight adventures and trail runs in challenging weather conditions. Its sleek, streamlined design and fully taped seams ensure you stay dry and comfortable no matter how demanding the elements become.
Crafted with PFC-free Pertex® Shield fabric featuring a 3-layer membrane, the Fastier delivers outstanding water and windproof performance without sacrificing breathability or durability. The adjustable hood, equipped with a stiffened brim, offers superior protection, while the convenient chest pocket is perfect for stashing gloves or energy gels. Designed for performance, the Fastier packs effortlessly into a running vest, belt, or backpack—making it the ideal companion for lightweight travel.
Despite its featherlight build, the Fastier is tough enough to withstand the rigors of ultramarathons, offering long-lasting durability. A two-way zipper allows for harness accessibility, making it a versatile choice for climbers as well.
