Best Running Caps: 14 Hats Worth a Look for Training, Racing and Wet Weather

Introduction

A good running cap is one of those small pieces of kit that quietly earns its place on almost every run. It keeps sun off your head and out of your eyes, manages sweat, and can even help in wet weather if you pick the right one. With so many brands now making running-specific caps, the choice can feel overwhelming, so this guide rounds up fourteen hats that cover racing, hot-weather running, wet-weather running and everyday wear.

Hoka Run Hat

The Hoka Run Hat is a clear favorite for key sessions, races and long runs. It comes down largely to fit: a comfortable, rounded peak, a big front panel that soaks up sweat, breathable side panels, and a design that looks good in a wide range of colors. It costs around £30 or $30, so it is not the cheapest cap, but previous versions often appear in Hoka sales when new colors launch.

Montane Minimus Light Waterproof Cap

For wet-weather running, the Montane Minimus Light Waterproof Cap is a strong pick. The waterproof brim in particular helps keep glasses clearer during rainy runs, which matters more than you might think. The thin material means it does not get overly sweaty despite being waterproof, and it packs down small. Older versions can still be found at third-party UK retailers for roughly £15 to 20, while newer versions on Montane’s own site cost more but should perform just as well.

If you dislike running with a hood up because it reduces awareness around busy areas, a waterproof cap like this is a much more comfortable alternative. It will not keep you completely dry, but it takes the edge off the worst of it.

On Lightweight Cap

The On Lightweight Cap is a premium five-panel design with highly breathable dotted side panels, a large front section, and a nicely rounded brim. It costs £40 or $45, which is fairly expensive, but it works well on long runs, short runs and fast runs alike. It also has a built-in sweatband, thin fast-drying fabric, a machine-washable build, and an easy clasp at the back for dialing in fit. One tester has used the same cap for four or five years and it is still going strong.

For racing and focused training, it is a go-to: comfortable across a mix of distances, breathable when sweating, and easy to loosen slightly as things heat up. The brim is not soft or packable, but that matters little if you plan to wear the cap throughout a race anyway.

Columbia Speed Trail Cap

The Columbia Speed Trail cap is a versatile, super-lightweight option made for running, hiking and trails, but it is equally happy on hot urban summer runs. It features a built-in sweatband, thin fabric, and a laser-cut vented body with perforations running right across the top for strong breathability. A clever drawcord toggle at the back gives a good adjustable fit, and the soft, flexible peak makes it easy to roll up and stash in a belt or vest. It is hand wash only but easy to clean and dries fast.

2XU Run Cap

The 2XU Run Cap keeps things simple with six panels cut from light fabric, four small vented sections on top, a rigid peak, a Velcro fastening at the back, and a built-in sweatband. At £20 it is the cheapest of the performance-style picks here, yet it does a very similar job to pricier options and has been worn through plenty of races.

Buff Five-Panel Air Cap

The Buff Five-Panel Air Cap is aimed squarely at very hot, sweaty conditions. The design is very well ventilated, and the standout feature is fit adjustment on the move: pull the cord to loosen or tighten without taking the cap off, something not every cap allows. It is also packable, with just enough firmness in the brim to still offer proper protection when packed away.

Ciele Go Cap

The Ciele Go Cap is one of the designs that has been there since the brand’s start, and it has stood the test of time. It is really comfortable, making it an ideal daily-run cap that also copes in hotter conditions. Ciele’s Coolwick construction works well once you start sweating, keeping the top of your head from feeling hot and clammy. The brim is semi-flexible so it can be packed away, the clasp is easy to adjust and tucks inside the cap, and it washes well, staying in good condition over years of use.

Acid Running x Fractel Cap

The Acid Running x Fractel collaboration blends Acid Running’s aesthetics with Fractel’s performance-focused cap construction, and Fractel is an Australian running cap brand with a strong track record. The light, soft material is comfortable first and foremost, the brim is semi-flexible for packing away, and the strap end tucks neatly inside the cap. It is the kind of cap that looks good when you are not running and still delivers when you are, making it a perfect holiday running cap.

Asics Five-Panel Cap

The Asics five-panel cap is possibly the simplest on this list, but it is a solid all-rounder. Loads of colorways are available, and the fit is notably deep, which matters if you find shallow running caps sit too high on your head. It fits comfortably, sits nicely and low, and has been used for both races and training over several years. It sits at a mid-range price and is well worth a look if you want a nice-looking, dependable cap.

Sprints Running Cap

Sprints makes a wide range of running caps, and the appeal is largely design-led: they are well made, look great and come in genuinely fun patterns, from banana designs to dog themes and running-club graphics. Despite feeling a bit thicker than some caps, the banana version held up well in a heat wave and stayed comfortable. There are also deeper, more fashion-forward versions that work well as everyday caps, plus a performance model for those who want a more race-oriented build.

On Running Cap

At £75 in the UK, the On Running cap is a very expensive proposition, so it only makes sense if you genuinely want the lightest, most breathable cap available. It is extremely lightweight, with a thin design, a front section with holes to reduce weight, and a see-through mesh top. That breathability is the selling point, but the see-through top is also the catch: it lets sun through, so without sunscreen on your head it does little to prevent sunburn.

Kiprun Running Cap

The Kiprun running cap is a genuine bargain at £11.99 in the UK. Kiprun caps used to be the kind of thing you grabbed as a temporary replacement, but this version is a really nice-looking cap with soft material, a comfortable deep head section and modern design details. It is as good as caps costing £35 or £40, comes in plenty of colorways, and gets used constantly even when more expensive caps sit in the drawer.

If running caps have been getting more expensive and you want one or two good ones without spending much, this is the cap to beat.

Kiprun Ultra Light Trail Running Sun Hat

Not a running cap but a running hat, the Kiprun Ultra Light Trail Running Sun Hat costs just £14.99 and offers far more coverage than a standard cap. It protects the back of the neck and the ears while staying genuinely lightweight and breathable, with performance close to a normal running cap. That makes it ideal for long, hot trail days, summer half marathons on exposed routes, or hikes, where it is easy to wash and keeps sweat under control.

Grasmere Verdant

The Grasmere Verdant comes from a brand-new company called Grasmere, with only a limited initial run of caps, though more are planned. Four versions exist, one colorway per season, and the Verdant is a subtly styled cap with nice little color accents rather than anything neon. It fits comfortably with good depth, holds on well, and looks nice enough to wear as a casual cap as well as for running. Upcoming seasons bring the same design in different colors, and the quality and understated look make it worth a look if you want something a bit different.

Overall Buying Advice

If you want a single do-it-all cap, the Hoka Run Hat and On Lightweight Cap are the strongest all-rounders, with the Ciele Go Cap close behind for daily use. For hot weather, the Buff Five-Panel Air Cap and Columbia Speed Trail cap lead on ventilation and adjustability, while the On Running cap offers maximum breathability at a premium price if sun exposure is not a concern. For wet weather, the Montane Minimus Light Waterproof Cap is hard to beat.

Budget shoppers are well served too: the Kiprun running cap at £11.99 punches far above its price, the 2XU Run Cap at £20 covers racing and training cheaply, and the Kiprun sun hat adds coverage for barely more. If design and individuality matter most, look at Sprints or the new Grasmere Verdant.

Conclusion

There is no single best running cap for everyone, but there is almost certainly one on this list that matches how you run. Match the cap to your main use case, whether that is racing, hot summer miles, wet winter roads or everyday wear, and any of these picks will serve you well. Check current pricing and availability, as several of these caps regularly appear in sales.
