What Should I Wear Trail Running in the Summer?

Written by Lauren Haislip

Morning dew sparkles on forest leaves as birds trade gossip overhead, and the trail ahead dares you to chase the sunrise. But summer isn’t all picture-perfect. You’ll dodge sun-baked roots, welcome surprise downpours, and feel the heat climb like an oven around you. Dialing in your running trail gear, no matter the forecast, is the secret to turning sweaty struggles into smooth, sun-soaked miles. Read on for the PR Run & Walk kit that’ll keep you breezing through summer singletrack.

Apparel: Light, Breathable, Performance-Driven

When summer trails heat up, your clothing choice is as important as your running shoes. The goal is to regulate body temperature, stay dry, and prevent chafing. We’ve organized apparel into key subcategories so you can zero in on exactly what you need.

Shirts & Singlets for Maximum Ventilation


Your upper layer should be made of moisture-wicking fabrics that pull sweat off your skin and dry quickly.

Vuori Elevation Racerback Tank

Feels almost weightless but eats sweat faster than you can blink. The snug racerback cut keeps straps out of your way, so your arms can swing freely up every incline without a second thought.

Nike Stride Short Sleeve

Think of this as your trusty go-to on blistering days. It uses Nike Dri-FIT to whisk away sweat and vents in all the right spots so you stay dry. The athletic cut follows your body’s moves perfectly, with no extra fabric flipping when you pick up the pace downhill.

Trail Running Shoes: Grip, Protection, and Breathability

Ever had your heart skip a beat because your foot slid on a loose rock? I have. That’s why you need shoes that dig in like they’re superglued, dump creek water before you realize you’re soaked, and mold to your foot so every step feels like home.

HOKA Speedgoat 6

If cloud-level cushioning is your jam, the Speedgoat 6 has got you covered with its plush midsole and sticky Vibram® Megagrip lugs that grab hold whether the trail is drenched or dry. The engineered mesh upper keeps fresh air flowing without ever feeling floppy or flimsy.

Altra Lone Peak 9

These feel-like-foot skin shoes offer a zero-drop sole and an open toe box so you can really dig in. The lugged MaxTrac outsole grabs gravel and mud alike, and the mesh panels let water flow out the moment you splash through a stream. No soggy socks, guaranteed.

Brooks Cascadia 18

Slip into these and you’ll tackle any terrain with swagger. The hidden rock shield sends sharp debris packing, while the quick-dry mesh and side vents blast away mud and heat. No root, rock, or bog can slow you down.

Socks: Small Investment, Big Comfort

Think socks are just an afterthought? Think again. In muggy, sweat-forcing conditions, they’re your unsung heroes: wiping moisture away, supporting your arches, and giving your toes room to breathe even when the trail heats up.

Feetures Elite Ultra Light Socks

These socks wrap your arch in gentle compression and lay flat at the toes to prevent rubbing, while mesh vents whisk sweat away before hot spots form.

Shop Feetures Socks

Balega Ultralight Socks

Think plush terry loops meet sweat-wicking magic. These no-show socks lock around your heel and forefoot so nothing slips or bunches, even on triple-digit mile days.

Tip: Opt for ultra-light styles with padding exactly under your heel and toes. That sweet spot cushioning stops hot spots before they ever start.

Hats, Shades & Accessories: Sun and Sweat Solutions

When the sun refuses to take a break, a solid hat and reliable shades are your trail armor. They channel sweat away from your eyes, crush glare before it slows you down, and block rogue twigs or flying grit so you stay locked in on every footfall.

JUNK Big Bang Lite Delta Force

Wear this tube as a headband, neck gaiter, or sweatband; its moisture-wicking quick-dry fabric has you covered.

Goodr OG Sunglasses

Final Tips for Summer Trail Running

Acclimate Gradually

Treat your first summer runs like catching up over coffee: easy, fun, and totally pressure-free. Head out in the cool morning air for a quick lap, then only add extra miles when you’re still laughing at the trail’s quirks.

When in Doubt, Slow It Down

When the sun turns the trail into an oven, toss your stopwatch aside. Glide into a pace that feels good, break into power walks on the climbs, and let the wildflowers, whispering pines, or that epic view call the shots for your speed.

Keep Your Fuel Close

When temps soar, your body runs on more than air. Tuck a gel, chew, or bar into your vest and refuel every 30–45 minutes. Pair it with electrolyte tabs in your flask so you keep your energy and sweat salt in check.

Dress for Drama

A misty start can turn into a downpour fast. Throw a lightweight rain shell or quick-dry top from our Apparel Collection in your pack so you’re never caught off guard.

Be a Trail Buddy

Smile, say hello, and yield to uphill runners. Announce your passes with a friendly “on your left,” and carry out any trash you bring in. Reflective pieces from our Hats & Headwear and Safety & Visibility lines also help everyone stay safe.

Watch for Critters

Summer brings ticks, mosquitoes, and maybe a snake sighting. Spray on some bug repellent before you head out.
