A wave of designers ups the sportswear game from Golden State-standard board shorts to refined garments that marry classic forms with a breezy street aesthetic.

Begun in 2008 as a men’s denim label, Simon Miller has evolved into a robust lifestyle brand that now includes outerwear and trousers, a women’s line, and a variety of handsomely articulated and superbly constructed leather bags. Under the guidance of co-creative directors Daniel Corrigan and Chelsea Hansford, the spring/summer collection, starting at $200, includes a variety of austere bomber jackets and perfectly cut jeans, and focuses on texture — pigment-painted linens, waxed cottons, indigo-stained denim. Japanese-inspired flourishes such as kimono-style belting make their clothes fun and futuristic.

Founded in 2012, John Elliott’s sportswear line features custom fabrics, clean lines and a predisposition toward effortless layering. Elliott has earned a hyper devoted following thanks to his erudite take on the basics — jeans, hoodies, and tees, ranging from $65 to $1,610. The line blends simple streetwear like flight jackets and cowl-neck sweatshirts with pieces that are more chic, including tunic-length tees and fishtail raincoats. When GQ named Elliott one of the best new menswear designers in 2014,the mag cited his “savant-grade expertise,” comparing him to math mind John Nash. Smart!

Self-described as an “avantstreet” lifestyle brand, Stampd is the brainchild of creative director Chris Stamp, who started by customizing sneakers — hand-painting singular Chuck Taylors — before officially launching his line in 2011. Known for its monochromatic take on West Coast streetwear, the spring collection lightens up with pale denims — in the form of distressed jeans and oversize button-downs — and tastefully deployed earth-toned coats and blazers. Stampd’s signature flat-brimmed caps, $55 to $140, are executed in everything from premium leathers to padded nylon in patterns and solids — tops for SoCal tastemakers.

Launched by Scot Shandalove and Jake Zeitlin in 2013 and named for the French word for material, Matiere’s creative vision is grounded in constructing clothes and outerwear from innovative fabrics, particularly those of the luxe variety. The label’s 2016 spring/summer collection, which was presented at New York Men’s Fashion Week, includes knitted and brushed cashmere, Japanese “technical” fabrics and a color palette focused primarily on black, white and indigo. Textured minimalism elevates the simple lines and silhouettes of Matiere’s trousers and jackets into pieces that are both wearable and collectable. The collection starts at $55.

Established in 2013 by Anthony Franco and brothers Jacob and Joshua Willis, Second/Layer makes clothing that is self-described as “Chicano/minimal,” which is kind of perfect for the label’s distinct take on LA streetwear. More than a simple homage to California’s cholo skate culture, Second/Layer earned its solid rep by elevating the basics to a new level of chic. Slouchy hoodies, bomber jackets and baggy trousers start at $150. The label’s spring/summer collection shows off head-to-toe vertical stripes, white denim, drawstring pants and a variety of logo-emblazoned sweatshirts and tees, all paired perfectly with a signature baseball cap printed with the statement, “Laidback Lover.”

Inspired by “the times and travels of the Pacific man,” Los Angeles-based CWST is a label obsessed with the mythos of Southern California. Created by longtime friends Derek Buse and Joe Sadler, the clothes, ranging from $135 to $955, are a kind of casual extravagance: trousers, button-downs, tees and jackets that are sublime in their simplicity but rendered in fine linens and delicate knits, all characterized by an almost pathological attention to detail. The spring/summer collection is an extended nod to Death Valley — all scorched pastorals and sunburnt textures that make even the hottest place in North America seem impossibly cool.

Since debuting last year, Reader x Fields has quickly become a go-to for men interested in impeccably designed shirts, all $120. The brainchild of LA native Jason Fields, the line exclusively produces collared button-ups (available in a minimal club collar and an even quieter band collar) in a variety of muted colors that are cut from finely milled fabrics — the soft chambrays are a fan favorite — and constructed in the heart of Los Angeles. Given the meticulous quality and attention to detail, it’s easy to see why Reader x Fields has become a favorite of chic celebs like Adam Levine.
