You're standing in the Plaza del Ayuntamiento. It’s 8:00 AM on July 7th. The air is thick with the smell of cheap wine, sweat, and gunpowder from the chupinazo rocket. Look around. It is a sea of white and red. If you showed up in cargo shorts and a neon "I Heart Spain" t-shirt, you're going to feel like a total outsider. Honestly, the running of the bulls clothing tradition isn't just about looking the part; it's a deep-seated cultural uniform that dates back over a century. You aren't just dressing for a party. You’re dressing for a ritual.
Most people think you just grab a white shirt and a red scarf and call it a day. It's more nuanced than that. If you’re actually planning to run—meaning you're physically in the street with six 1,300-pound animals—your wardrobe choices could literally be the difference between a clean escape and a trip to the Hospital de Navarra.
The San Fermín Uniform: Why White and Red?
The base layer is simple: white pants and a white shirt. Why? There are a few theories. Some historians point to the txistularis (traditional Basque musicians) who wore white. Others suggest it was a way for the poor to look uniform without spending a fortune on high-fashion garments. Whatever the origin, by the time Ernest Hemingway arrived in the 1920s to write The Sun Also Rises, the look was already cementing itself as the standard for the Fiesta de San Fermín.
The red accents—the pañuelico (neck scarf) and the faja (waist sash)—are tributes to Saint Fermín, the first bishop of Pamplona. Tradition says he was martyred by decapitation in France. The red symbolizes his blood. It's a heavy thought for a festival that feels like a giant street party, but that's Spain for you. The sacred and the profane are always shaking hands.
Don't put your scarf on until the opening ceremony (the Chupinazo) on July 6th at noon. Doing it early is the ultimate "I'm a tourist" giveaway. Once that rocket goes off, everyone ties their red scarf around their neck simultaneously. It’s a wild sight.
Choosing the Right Fabric for the Heat
Pamplona in July is brutal. It’s hot. It’s humid. It’s crowded.

You’ll see people wearing heavy denim or thick cotton. Big mistake. You want breathable fabrics. Look for cotton-linen blends or high-quality poplin. Avoid synthetic "athleisure" fabrics if you can help it. While they wick sweat, they don't hold up well if you take a tumble on the cobblestones. Natural fibers have a bit more "bite" and won't melt against your skin if there's friction.
White gets dirty. Fast. By noon on day one, your running of the bulls clothing will likely be stained with calimocho (a mixture of red wine and cola). Many veterans buy cheap white clothes with the intention of throwing them away at the end of the week. However, if you want to look sharp, bring two or three sets. There are plenty of laundromats in the Casco Viejo (Old Quarter), but they’ll be packed.
The Anatomy of the Pañuelico and Faja
The red scarf is the soul of the outfit. You can buy them at any street stall for a few euros, but the locals usually have high-quality embroidered ones. Some have the coat of arms of Pamplona; others have the image of San Fermín.
- The Scarf (Pañuelico): Fold it into a triangle, roll it up, and tie it with a simple knot. Some people use a slide, but a knot is more traditional.
- The Sash (Faja): This is where people get confused. The faja is a long red belt. It’s supposed to be wrapped around your waist multiple times. It actually serves a purpose—it provides a bit of core support, almost like a weightlifting belt, which is handy if you’re sprinting for your life. Always tie it on the left side.
Footwear: The Most Ignored Safety Feature
If you are actually running, your shoes are the most critical part of your running of the bulls clothing kit. Flip-flops? Forget it. Sandals? You’re asking for a broken toe.
You need grip. The cobblestones in Pamplona are notoriously slippery, especially if it rained or if there’s spilled drink on the ground. Professional runners often wear white sneakers with decent tread. Brands like Munich (a Spanish brand) are popular among the mozos (the local runners).

One specific tip: make sure your laces are tucked in. If another runner steps on a loose lace, you’re going down. And in the middle of a bull run, "down" is the last place you want to be. The bulls aren't actually the biggest danger; it's the "pile-up" of other humans. Having sturdy, closed-toe shoes allows you to navigate the chaos without losing a toenail.
What Not to Wear (The Danger List)
There are rules. Some are cultural, some are enforced by the Policía Municipal.
- GoPro Chest Mounts: Don't do it. If you’re running, you aren't allowed to carry cameras or recording devices. They’ll pull you out of the line before the bulls are even released.
- Backpacks: Absolutely not. They are a snag hazard and make you wider, which is bad in a tight corridor like Calle Estafeta.
- Capes or Loose Clothing: Anything that can get caught on a horn is a death trap. Keep your silhouette clean.
- Dangling Jewelry: Same logic as the backpacks. If a horn catches your necklace, it’s not going to end well.
Where to Buy Your Gear
You have three options.
First, you can buy everything before you go. This is the "safe" route. Search for traditional Spanish outfitters online. Second, you can hit the big department stores like El Corte Inglés once you land in Spain. They usually have massive sections dedicated to San Fermín clothing.
Third, and most common, is buying from the street vendors in Pamplona. On July 5th and 6th, the city turns into a giant market. You can get a full outfit—pants, shirt, scarf, and sash—for about 30 to 40 euros. It won't be Armani quality, but it'll get the job done. Just be aware that the "white" of the street-vendor clothes is often a weird, slightly blueish-white that looks different from more expensive cotton.

The "After-Run" Layering
The run happens at 8:00 AM, but the party goes 24/7. Once the bulls are in the corral, the morning shifts into breakfast. This usually involves magras con tomate (ham with tomato) or chocolate and churros.
Because you’ll likely be out all day, consider a light white jacket or a long-sleeved white linen shirt to layer over your t-shirt. Even in July, the shade of the narrow streets can be surprisingly cool in the morning.
Practical Insights for the Modern Traveler
Honestly, the best advice I can give you about running of the bulls clothing is to embrace the mess. You are going to get red wine on you. You are going to get dust on you. You might even get some bull snot on you if you’re lucky (or unlucky).
If you’re traveling light, don't pack five sets of white jeans. Pack two and find a wash-and-fold service. Also, wear white underwear. Trust me. When white pants get wet—either from rain or spilled drinks—they become transparent. It’s a lesson many tourists learn the hard way in front of thousands of people.
Also, think about your pockets. You need a way to carry your phone and some cash, but you don't want bulging pockets if you're running. A small, flat money belt worn under your shirt is much safer than keeping a wallet in your back pocket, where it can easily fall out or be nicked in the crowd.
Actionable Checklist for Your Kit:
- White Trousers: Look for "Chino" style cotton. Avoid cargo pockets.
- White Shirt: Short sleeves for the heat, button-down for the look.
- Red Scarf (Pañuelico): Buy it in Pamplona for the authentic crest.
- Red Sash (Faja): Make sure it's long enough to wrap at least three times.
- Shoes: Tennis shoes with rubber soles. White is traditional, but comfort and grip win every time.
- Protection: Sunscreen is mandatory. You'll be outside for 12+ hours.
When you finally put the outfit on, you'll feel the shift. You aren't just a spectator anymore. You're part of the tapestry. Just remember: tie that scarf tight, keep your laces tucked, and when you hear that first firework, get ready to move. The white and red isn't just a costume—it's your armor.
Next Steps for Your Trip
- Verify your shoe size in European measurements (e.g., a US Men's 10 is a EU 43) to make buying sneakers in Spain easier.
- Purchase a high-quality cotton Faja early as the cheap polyester ones tend to slip and unwrap while running.
- Locate a "Lavandería" (Laundromat) near your accommodation on Google Maps before you arrive, as you will definitely need to wash your whites by day three.
