The Best Summer Blazers for Warm-Weather Events (2024)

• Materials: 100% linen
• Care: Dry clean only

Alex Mill's Mercer blazer blends several different styles into one unique coat. Part-chore coat, part-shawl collar jacket, part-blazer, it's lightweight without being shirt-like, knit a bit thicker and casual while still being incredibly cool.

Our tester found the blazer fit well through the shoulders, across the chest and down the arms, but it runs short, hitting the hips more like a trucker jacket than a blazer, which usually covers the rear and hangs over both hip pockets. It looks more formal than Buck Mason's, for example, but it doesn't look polished enough for a traditional office space or to be the best man in a wedding. The smaller, pointed lapels make quite the statement, though, our tester says, a feature not found on most affordable jackets.

Just because trying to stay cool doesn't mean you can't look cool, too. An unconstructed blazer adorned with a pattern can trick the eye into seeing lines where there aren't — simply put: it'll look more put together than it actually is. Bonobo's linen blazer, which is cut from breathable linen fabric, is proof! For being both lightweight and unlined, it appears all there without extra weight.

• Materials: 97% cotton, 3% spandex
• Care: Machine washable on cold

Buck Mason's relaxed-fit Carry-On Jacket — aka a blazer — is cut from lightweight stretch cotton (97 percent cotton, 3 percent spandex). Stretch let the designers ditch the back vent (and the excess fabric needed for one); patch pockets without flaps shed weight; and opting for no cuff buttons makes this option even more casual. Overall, it's a winner worth wearing to every semi-formal summer event.

This is also an ideal, hence the name, suit for traveling, commuting or casual (yet semi-formal) lunches, dinners or dates. It does, however, have a slightly modern fit, meaning it's a little short in sleeves and kind of chore coat-ish.

This blazer by Banana Republic relies on active particles derived from volcanic sand to regulate your body temperature. Dubbed 37.5° Technology, it's not something BR came up with but rather outsources for its designs. Case in point? The Core Temp Blazer, which runs a little big but proves plenty flexible.

Plus, it's built like a regular blazer: flattering in the shoulders but the right proportions still, meaning it hits past the hips and the sleeves run down to your wrists.

Although most linen doesn't stretch (and thus wrinkles), this Bonobos blazer does, courtesy of its 96 percent linen, 3 percent polyester and 1 percent elastane construction. Pair it with the brand's matching pants or put it together with light jeans. It'll look good in either scenario, especially since it's semi-lined, a feature you rarely find on sub-$500 jackets.

• Material(s): 72% cotton, 28% linen
• Care: Dry clean only

J.Crew has carved a new lane for itself: casual suiting. This cotton-linen chore blazer is no exception. It's unstructured yet flattering, simple yet statement-making and appropriate in both the middle of summer and the first few weeks of fall.

Our tester says it does run slightly small, but the jacket itself isn't designed to be tailored like something you'd order custom off Savile Row. It does have semi-lined, slightly unstructured shoulders, tighter sleeves and a chore coat-like body, but obvious lapels, not a folded collar. And it isn't just the three bucket pockets that resemble the famous workwear style, but the super-straight bottom hem, too.

Available in three colors, olive, tan and black, Mango's affordable linen blazer proves slim-fit, but flattering still. It isn't too tight but plenty tailored, making it good-looking with cotton or linen dress pants.

Some wearers have complained that the sleeves are a little short, though, something that comes with the territory, we'd say (being slim-fit). If you want a regular shape, with regular-length sleeves, try sizing up.
