SIERRA DESIGNS
Founded in California, USA in 1965. The brand develops products that blend outdoor functionality with contemporary fashion sensibilities, designed for those who enjoy incorporating outdoor elements into everyday style.

Durable and water-resistant “60/40” fabric
This piece uses the revolutionary “60/40 (Rokuyon Cloth)” fabric developed by Sierra Designs in 1968. Woven with a ratio of 60% cotton for the weft and 40% nylon for the warp, it is softer than 100% cotton and more abrasion-resistant than 100% nylon. The fabric develops richer character with wear. When exposed to moisture, the cotton fibers swell to tighten the weave, enhancing water resistance and wind protection.
A polyester liner is applied to the interior to improve wind resistance while allowing smooth layering and easy movement of the sleeves.
Functional details
The shoulder area features raglan sleeves for a natural fit and ease of movement. The front is finished with a concealed placket combining snap buttons and a zipper.
The pockets are designed vertically for easy access, and an interior pocket with hook-and-loop closure is also included.
The cuffs can be adjusted in two stages with buttons, helping to block wind from entering through the sleeves.
A versatile piece for both on and off duty
With its clean, basic design, it works effortlessly with casual outfits, refined layered looks worn over a jacket, and even business-oriented styles.
Highly practical and adaptable, this is a versatile piece that performs across a wide range of situations.
