I bought one of these last year and I love it. Keeps me dry and breathes well and I rode with this jacket and an Under Armor cold weather base layer and thin synthetic fabric t-shirt in low 30's temps and I was not cold at all. In colder areas than the Puget Sound region I think I would layer a bit heavier but this jacket is great at least for me and a heck of a lot less expensive than the SP.
