Ibex Men's Breakaway Jacket 800 F11

Aerobic activity is about efficiency. Burn too much energy, too soon and the day gets a lot longer. The Breakaway 2 jacket keeps a body at its most efficient, not too warm but protected from the cold. The secret is Climawool, a four-way stretch wool blend. (Think magic sheep.) Details like articulated elbows, reflective logo racing stripe and a cavernous back pocket make this one of our most technical pieces, though it remains understated so you can snag a post-workout coffee without feeling like a NASCAR driver. (Unless you are a NASCAR driver.)
