During the summer, there is no shortage of occasions for which you will be expected to wear a suit. Whether you are attending a wedding, charity event, or cocktail hour, you will need to be prepared with a suit that will keep you looking stylish but cool at the same time.
When dressing for warmer months, your primary consideration should be the fabric of your suit. Here at Christian Boehm, our custom clothing experts have put together this helpful guide to help gentlemen everywhere determine the best suits and sports jackets for summer.
WEIGHT MATTERS
Knowing the weight in grams or ounces of the cloth used in your suits or jackets is essential and will be a determining factor of how cool you will feel when wearing your garment before you make a purchase.
SUMMER WEIGHT
When wearing a suit or jacket in a tropical climate, opt for cloth in 7-8.5 ounces or 200-240 grams. On the upside, these are very lightweight and ideal when temperatures rise above 85 degrees.
On the downside, they can be too light when the temperature falls below 70 degrees.
SEASONLESS OR 4-SEASON WEIGHT
When wearing a suit or jacket in a climate where you live through all four seasons, opt for cloth right at 9 ounces or 255 grams. On the upside, these are very comfortable to wear in any climate and are preferred by most consumers looking to stretch their investments in their garments.
On the downside, they can be too light when the temperature falls below 50 degrees.
FALL/WINTER WEIGHT:
When wearing a suit or jacket in a climate where the temperature falls below 50 degrees regularly, you may opt for cloth at 11-13 ounces or 310 to 365 grams. On the upside, these are very comfortable to wear in any climate where it’s bone-chilling cold in the Fall and Winter months, like Chicago, Toronto, or Cleveland.
On the downside, they can be too heavy to wear when the temperature rises above 60 degrees.
BEST TYPES OF CLOTH FOR WARM WEATHER
Summer’s best clothes are summer weight wools, cotton, seersucker, linens, silks, and various blends of the options mentioned. See below for a great guide written by our Christian Boehm style experts.
SUMMER WEIGHT WORSTED WOOLS
Summer Worsted Wools make you not only feel great in warm weather, but they look amazing on. The word “worsted” refers to the industrial combing of raw goods as part of their milling process. A great example of summer-weight wool would be Vitale Barberis Canonico’s Blassone by Gladson. You can view the collection by clicking the video link.
COTTONS AND SEERSUCKER
Seersucker is when cotton is woven with a crinkled vertical line in the goods. They are lightweight and comfortable in tropical climates or the dog days of summer in northern climates. See a great video example of seersucker cotton fancies.
The best kinds of cotton are long staple cotton which produce the finest feel and best performance when spinning the yarns into cloth. With advancements in technology, mills have discovered that blending high-quality long-staple cotton with a bit of lycra provides a cloth with stretch, which makes it extremely comfortable.
See our video for great examples of cotton and lycra custom suits, blazers, or pant fabrics.
SILK
Silk is spun from the cocoon of the silkworm. It is featherlight and has the inherent characteristic of giving a beautiful luster to the garments. Most silk jackets made with silk are blended with other summer fabrics, such as lightweight wool or linens.
A great example of a summer silk and wool blend is this 100% silk jacket made with cloth from the famed English mill Scabal’s Nobility collection. You can view the collection by clicking the video link.
LINEN
Like cotton, linen is made from a plant. Linen is made from the flax plant and has incredible natural wicking properties, which draws moisture away from the body resulting in a light and breezy garment.
Linen can be super soft or even stiffer depending on how they weave the cloth. The one characteristic of linen that may deter some people from buying linen is that it is guaranteed to wrinkle. It’s OK though, as the look of a linen suit, pant or jacket is one that is supposed to be soft and sporty casual. Don’t let the arm whiskers bug you; everyone knows you are wearing linen.
A great example of summer linen and wool blend jackets is made with cloth from Italian mill Kerry Knoll. You can view the collection by clicking the video link.
CONSTRUCTION
Construction is also an important component of how cool you will be when wearing a summer suit, jacket, or pant. Since Christian Boehm is Miami based, we frequently recommend jackets that are unlined and finished inside with taped seams to reduce the weight of the garment.
also, we will make the garments in a softer deconstructed construction that comes with minimal shoulder padding and interior chest padding. This will produce the right look for summer and give you what you want, which is the lighted construction in a jacket.
A great example of a lightweight constructed jacket is from the famed English mill Dormeuil ’s Dorsilk collection. You can view the collection by clicking the video link.
COLOR
Color is also a factor that can keep you cool in the summer. Darker colors like black or navy will absorb light, making you hotter. Lighter colors such as white, tan, and pale blue reflect light, which will keep you cooler but also give you the look of summer.
A simple tan and pale blue summer suit are great ads to your wardrobe. A great example is this seasonal fancy suit from famed English mill Dormeuil ’s Amadeus 365 collection. You can view the collection by clicking the video link.

Best Fabrics for a Summer Sport Jacket
A sport jacket is the most versatile garment in a warm-weather wardrobe.dress it up with tailored trousers or down with chinos and a polo. But in Miami, where humidity regularly hits 80% before lunch, the fabric you choose matters more than almost anything else. The right cloth keeps you cool, looks intentional, and holds its shape in the heat. Here is our guide to the best summer sport jacket fabrics, drawn from decades of fitting gentlemen in South Florida.
Linen and Linen Blends
Linen is the undisputed king of summer fabrics. Woven from the flax plant, its fibers are naturally breathable and moisture-wicking, pulling perspiration away from the skin and letting air circulate freely. A pure linen sport jacket in 7.8.5 ounce weight is the lightest option for Miami's heat, and the fabric's slubby texture gives any jacket an effortlessly elegant quality.
Let's address the obvious: linen wrinkles. That is not a flaw.it is the nature of the material, and those wrinkles are part of linen's charm. They signal a natural, breathable fabric rather than a synthetic imposter. This soft, unstructured look makes a linen sport jacket perfect for a Brickell lunch or a Coconut Grove sunset dinner.
For less rumpling, a linen-wool blend is an excellent compromise. The wool adds structure and resilience while the linen keeps the jacket light and cool. A 60/40 linen-wool blend in a hopsack weave is one of our most requested summer combinations at Bespoke By CB.
Hopsack Weave
Hopsack is not a fiber but a weaving technique.an open, basket-weave structure with tiny gaps between threads that let air pass through more freely than a tight weave. It can be woven from wool, cotton, linen, or blends, producing a fabric with a slightly rustic appearance that works beautifully for sport jackets.
A navy hopsack jacket in 9-ounce tropical wool can serve as your -to for client meetings, gallery openings, and dinner dates alike. The texture catches light differently than a smooth worsted, adding visual depth without looking flashy. See our full summer suits guide for more on weight and weave.
Cotton-Linen Blends
Cotton-linen blends occupy the sweet spot between structure and softness. Cotton provides body and shape retention while linen contributes its signature breathability. The result looks more polished than pure linen but feels cooler than pure cotton. A mid-blue or oatmeal cotton-linen jacket pairs effortlessly with white trousers for a classic Miami look.
Fresco and Tropical Wool
For business-casual settings where a sport jacket is expected but the heat demands something lighter, fresco and tropical wool are the answers. Fresco is a high-twist wool with an open, porous weave that maximizes airflow. The high-twist yarns give it a crisp hand and excellent wrinkle recovery despite its light weight. A fresco sport jacket in light grey or taupe at 8.9 ounces is perfect for a Brickell afternoon meeting, and because it is 100% wool, it drapes beautifully and holds its shape all day.

Bamboo Fabric
Bamboo is a newer entry in tailored clothing with a devoted following. Its fibers are naturally cooling, moisture-wicking, and silky soft against the skin, with a subtle sheen and fluid drape that gives a sport jacket a refined look. Bamboo is also one of the most sustainable raw materials available.it grows rapidly without pesticides and requires far less water than cotton. We often recommend it blended with a small percentage of wool for added structure.
Seersucker
Seersucker is the classic Southern summer fabric, and its credentials for Miami are impeccable. Its puckered surface is created during weaving.alternating tight and slack tensions produce a crinkled texture that holds the fabric slightly away from the skin, allowing air to circulate and preventing the cloth from clinging on the most humid days. A seersucker sport jacket is a statement of relaxed confidence, perfect for a Coral Gables brunch or daytime charity event, and its inherent wrinkle-resistance makes it ideal for travel.
Lightweight Cashmere Blends for Air-Conditioned Environments
Miami presents a unique challenge: the outdoors is sweltering, but restaurants, offices, and venues are often aggressively air-conditioned. A lightweight cashmere blend.roughly 10% cashmere with summer-weight wool.gives you a fabric that is soft to the touch, providing just enough insulation when the AC is blasting without becoming oppressive when you step outside. A charcoal or midnight navy cashmere-wool sport jacket at 9.10 ounces bridges summer lightness and year-round comfort.
Frequently Asked Questions About Summer Sport Jacket Fabrics
What is the best sport jacket fabric for Miami's humidity?
For Miami's humidity, we recommend pure linen or a linen-wool blend in 7.8.5 ounce weight. Linen's natural wicking and open weave allow maximum airflow.critical when the dew point climbs above 70°F. Hopsack weaves in tropical wool are the best alternative for a structured, business-appropriate look. Avoid tight weaves and heavy fabrics; anything above 10 ounces will trap heat and moisture against your skin.
Can I wear a wool sport jacket in summer?
Absolutely.provided you choose the right wool. Summer-weight worsted wools, fresco, and tropical wool are engineered for warm weather. Look for fabrics in the 7.9 ounce range with an open weave that allows air to pass through.
