You're going to need a warm layer for those unpredictable weather situations and a medium-weight bomberwill always do the trick. It's a classic that looks great with everything and if you choose a style like the MKI Black Bomber, you can dress it up or dress it down however you want.
Their bomber jacket is cut slim for a refined, tailored look and its 12oz fleece sweatshirt material isn't too heavy or too light. Inside, the jacket is satin lined and comes with a ribbed collar, cuffs, and hem. Colors come in a choice of navy, grey, or black.
