If a suit could be an overachiever—this lightweight blazer does the most thanks to a dressed up fabric that's also breathable, stretchy, and machine-washable. Plus, we left the back unlined so it's ideal for those who run hot. Tailored Slim Fit: Sits at the natural shoulder with an Italian-style soft shoulder expression. Fitted through the chest and waist. Notch lapel with 2-button front. Three exterior pockets, two interior pockets. Single back vent. Lined front body and sleeves, unlined back body.
