A good sun hat shades your face, neck and eyes — and finishes almost any summer outfit. It is one of the rare accessories that is equally practical and beautiful. On a crowded beach in Southern California, at a farmers market in Charleston or on a long walk through a national park in Utah, the right hat keeps you cooler, protects your skin and somehow makes a simple cotton dress or a linen shirt look like a choice rather than an accident. Yet many of us still grab whatever is hanging by the door, or buy a flimsy hat at a gift shop and wonder why it lasts one season.
Choosing a sun hat well is part science and part style. Below, our editors explain what to look for in brim size, material and fit, how to match a hat to your face and your plans, and how to care for it so it lasts many summers.
Brim size
A brim of about three inches or more shades your face and neck well. That is the most useful number to remember when shopping. Narrow-brimmed fedoras and baseball caps look sharp, but they leave the ears, cheeks and the back of the neck exposed, which are some of the spots most likely to burn on a long day outside.
Wider is not always better, though. A dramatic five-inch brim is wonderful on a beach chair or a garden party lawn, but it can catch the wind on a boat and block your view on a busy sidewalk. For everyday wear, a brim between three and four inches is the sweet spot. It gives meaningful shade without overwhelming your frame or turning every breeze into an event.
Pay attention to the shape of the brim, too. A brim that turns down slightly offers more shade to the face and neck than one that is perfectly flat or turned up. Many classic straw styles have a gentle downward curve for exactly this reason.
The right hat makes a plain outfit look intentional.

Materials
Straw breathes; tightly woven fabrics block more sun. That trade-off shapes almost every sun hat decision. The more open the weave, the more air moves through, and the cooler your head stays. The tighter the weave, the less light gets through. If you hold a hat up to a bright window and see lots of pinpoints of light, it will be cool but less protective.
Natural straw
Straw hats are woven from plant fibers such as raffia, palm leaves, paper straw or seagrass. They are light, breathable and classic. Tightly woven straw offers good shade while still letting heat escape. Raffia is especially popular because it is soft enough to pack, while stiffer straws hold a crisp shape but can crack if crushed.
Fabric hats
Cotton, linen and canvas bucket hats and wide-brim styles are washable, packable and often very practical for hiking and travel. Some outdoor hats are labeled with a UPF rating, which indicates how much ultraviolet light the fabric blocks. A UPF of 50 is a common benchmark for sun-protective clothing. Fabric hats tend to be warmer than straw, so look for ones with mesh panels or a vented crown for hot days.
Felt and wool
Felt hats are better saved for fall and winter. They look great, but they are warm and do not hold up well to sweat or summer rain.
Finding your shape
The best hat for you depends on your face, your height and your plans for the day. There are no strict rules, but a few guidelines help.
- Round faces often look balanced in hats with some height in the crown and an asymmetrical or angled brim.
- Long faces tend to suit wider brims and lower crowns, which add width and shorten the overall line.
- Heart-shaped faces pair nicely with medium brims that do not overwhelm a narrower chin.
- Petite frames usually look best in brims under four inches, so the hat does not swallow the whole silhouette.
- Taller frames can carry dramatic floppy brims with ease.
Fit matters as much as shape. A hat should sit comfortably on your head about an inch above your eyebrows, snug enough not to blow off but not so tight it leaves a mark. Measure around your head at that level with a soft tape before shopping online. Many hats include an inner drawstring or band that lets you fine-tune the fit, and a hat that is slightly too big can be adjusted with a strip of foam sizing tape inside the band.
Matching the hat to the day
Think about where you will actually wear the hat most. A beach hat should be packable and water-friendly; raffia or a cotton bucket style works well. A city hat might be a structured straw boater or a neat fedora with a modest brim, easy to wear on a crowded sidewalk. For hiking, look for a fabric hat with a chin strap, a UPF label and a vented crown. For a garden wedding or an outdoor party, this is the moment for a wider, more dramatic brim.
Color plays a role as well. Natural straw and cream are the most versatile summer shades and pair with almost everything. Black hats look striking but absorb more heat. A colored band or a simple scarf tied around the crown is an easy way to change the mood of one hat for different outfits.
Key takeaway: look for a three-inch brim, a weave that matches your plans and a fit that stays put in the wind.
Care and storage
A good straw hat can last for many summers with a little care. Store it on a shelf with the crown down or on a hat stand, never flat on its brim, which can warp. Keep it away from a hot car dashboard, where straw can dry out and crack. If it gets wet, let it air-dry naturally in its proper shape, away from direct heat. Wipe sweat from the inner band after hot days with a slightly damp cloth.
Fabric hats are easier. Most can be hand-washed in cool water with a gentle detergent and reshaped while damp. Check the care label first, especially for hats with a stiffened brim.
When traveling, pack a straw hat crown-up in your suitcase and fill the crown with socks or scarves to help it hold its shape. Or simply wear it on the plane.
Shade with style
A sun hat is not a replacement for sunscreen, sunglasses and good sense in the midday heat, but it is one of the easiest ways to make a long summer day more comfortable. Choose a brim of about three inches or more, pick a material that suits where you are going and make sure it fits well. Then let it do what the best accessories do: protect you, quietly, while making everything else you are wearing look a little more intentional.
Your face, your neck and your summer wardrobe will all be better for it.
