That's why we created this jacket. We've used the lightest, most elastic fabrics to make a jacket that blocks most of the wind, remains highly breathable and offers a very high level of water protection, oh, and it practically disappears on you so you don't notice it's there. This is a performance garment, and we've subordinated all our efforts to meet this challenge. We haven't added anything unnecessary, unless you consider the large reflective panel on the back unnecessary, but that's not the case. We've given the jacket a close-fitting cut so it doesn't flap in the wind, which also helps it retain more warmth. The pockets are generous and easy to access, the zipper slides easily and the logos are discreet.
