An examination into the first law of thermodynamics tells us that energy can neither be created or destroyed. According to this law, heat is a product of work, and a transfer of energy. In terms of cycling, your body puts off tremendous heat during high aerobic exercise in order to maintain an internal thermo-equilibrium. And when it comes to winter jackets, your choice is simply to harness this output or be harnessed by it. The Craft Performance Stretch Jacket does the prior by providing a lightweight, breathable design that's wind and waterproof. The Stretch Jacket's fabric selection and ergonomics does away with the notion of warmth being equatable to volume. When it's 50 degrees, we think you'll select this over a parka.
Craft's Performance Stretch Jacket is made from a combination of exclusive Craft fabrics that work in concert to provide an adaptable, ergonomic fit. The jacket achieves this by using a mix of polyester, spandex, and elastic fabrics; with the coup de grace being the Ventair X Wind material. As the names suggests, the fabric is not only windproof, but also waterproof. Working together in the Craft Body-Comfort System, they form a laminated soft shell with different materials selectively placed around the jacket. This system divides the body into different zones, and integrates the appropriate material on a zone-by-zone basis. The result is a contour-conforming fit that moves with your body in movement, not against it.
The Craft Performance Stretch Jacket is available in sizes from X-Small to XX-Large, and in the colors Amino/black, Black/flame, and Bright Red Black.
