The Summer Sale is on, and for once the weather is cooperating. With a heatwave settling in across Ireland, the pieces moving fastest at Hanley & Co over the past month are exactly what you would expect: lightweight polos, well-made tees and shirts that breathe. This is not a list of what we would like to sell you. It is a list of what has actually been selling, pulled from the last 30 days of sales in-store and at hanley.ie, with up to 50% off selected lines while the Summer Sale runs.
Here is what everyone else has been buying.
The Polos Leading the Summer Sale
The polo is the hardest working piece in an Irish summer wardrobe, and never more so than in a July like this one. Smart enough for an evening out, easy enough for the beer garden, and right at home at the Galway Races later this month.
1. Barbour Tartan Polo
Our bestselling polo of the past month by a clear margin, and a repeat of its run earlier this summer. The Barbour Tartan Polo works because it does not try to do too much; it takes the signature Barbour plaid, puts it on the collar trim of a clean pique polo, and leaves the rest alone. The weight is right for Irish summer weather, which is to say it works whether the heatwave holds or not. With 20% off Barbour in the Summer Sale, expect the popular sizes to go first.

2. Eton Jaquard Polo Shirt
The revenue leader in the polo category this month. Eton has been making shirts in Sweden since 1928, and it brings that shirtmaker precision to the polo: a considered collar, a clean placket, and a jacquard weave that gives the fabric a subtle texture you notice up close. It reads dressed up even worn casually, which makes it the polo to choose when the invitation says smart casual and means it. Wear it with tailored shorts now and lightweight chinos when the temperature drops back to normal.

3. Paul & Shark Double Mercerised Cotton Jersey Polo
If you want to feel the difference a fabric makes, start here. Double mercerised cotton is put through a finishing process that leaves it with a soft, almost silk-like handle, and it breathes exceptionally well in the heat. Paul & Shark has been building its reputation on technical fabric quality since the 1970s, and the linen details on this polo make it a genuine heatwave piece rather than just a good-looking one. Paul & Shark is 25% off in the Summer Sale, which for this level of construction is worth moving on.

4. Boss Orange Passenger Slim Fit Polo
A clean, slim-fitting staple from the more casual side of BOSS. No tricks, no oversized branding, just a well-cut polo that works as easily over jeans as it does over swim shorts on holiday. It has been selling steadily through the sale, helped by up to 30% off BOSS across the Black and Orange lines. If your polo drawer is due a refresh, this is the straightforward place to start.

5. Eden Park Short Sleeve Cotton Pique Polo
French rugby heritage, Irish summer weather. Eden Park was founded by Racing Club de France players in 1988, and the sporting DNA shows in how this polo is built: a pique texture with more substance than plain jersey, a collar that keeps its shape, and a fit that does not pull across the chest. It wears well across a long day, which is precisely what you want from a polo in this weather. Now 25% off in the Summer Sale.

The Tees Doing the Heavy Lifting
A good tee earns its place through fabric and fit, not branding. The four below have been the proof of that over the past month.
6. Gant Regular Fit Shield T-Shirt
The bestselling tee in the Summer Sale, full stop. A regular fit, a quality cotton with proper weight to it, and the understated Gant shield on the chest doing the talking quietly. It is the kind of tee that looks right under an open shirt, on its own with shorts, or with chinos when the evening calls for slightly more effort. With 20% off Gant, it is the easy answer to restocking summer basics, and the sales figures suggest plenty of people have reached the same conclusion.

7. Tommy Hilfiger Light Interlock Regular Fit Tee
The name does the explaining. Interlock cotton is a double-knit construction that gives a smoother, more substantial surface than standard jersey, and this is the lighter version of it, built for exactly this kind of weather. It looks sharper than a basic tee without trying to be anything other than a tee. One of those pieces customers buy once, then come back for in a second colour.

8. Giordano Luca Liquid Cotton T-Shirt
Liquid cotton is finished to give the fabric a fluid drape and a soft sheen, and the result sits well above what most people expect from a plain tee. It holds its shape through washing, drapes cleanly rather than clinging, and works as well under a blazer as it does on its own. A quiet bestseller that keeps earning its place month after month.

9. Belstaff T-Shirt
British heritage in its simplest form. Belstaff built its name outfitting motorcycle racers and long-distance travellers from the 1920s onward, and even its most basic pieces carry that build quality. A solid, well-made tee with the phoenix roundel kept small, it pairs as easily with shorts now as it will with a waxed jacket come autumn. Buy it for the summer, keep it for years.

Shirts Built for a Heatwave
When the temperature climbs past 25 degrees, fabric is everything. Linen, linen blends, poplin and short sleeves are what our customers have been reaching for over the past month, and every shirt below is built to keep you cool without losing the polish.
10. A Fish Named Fred Birdy Blooms Short Sleeve Shirt
The standout short sleeve shirt of the month. A Fish Named Fred is a Dutch brand that does print with personality, and the Birdy Blooms pattern is summer dressing done properly: confident, considered, and nowhere near beach-bar territory. The cut is relaxed without being sloppy and the cotton breathes well through a warm day. If florals are not your thing, the Sailing Boats print from the same collection has been selling alongside it.

11. Thomas Maine Roma Modern Fit Linen Shirt
Pure linen in a modern fit. Linen is naturally breathable, wicks moisture and dries quickly, which is why it has been the warm weather fabric of choice for the better part of a few thousand years. The Roma keeps the fit contemporary and the finish clean, so it works from a city break to a Sunday lunch that runs long without a change of plan. The creasing is part of the charm; anyone who tells you otherwise is overthinking it.

12. R2 Modern Fit Linen Blend Travel Shirt
The clever option. R2 builds shirts around a single idea: that a shirt should look as good at the end of the day as it did at the start. The Linen Blend Travel Shirt is a case in point. The cotton and linen blend gives you the airflow of linen with far less of the creasing, and the modern fit holds a clean line without stiffness. One of the most versatile shirts in the Hanley range, in a heatwave or out of one.

13. Gant Regular Fit Poplin Short Sleeve Shirt
Crisp cotton poplin, short sleeves and that unmistakable Gant cleanness. Poplin is a tight, smooth weave that keeps its structure in the heat, which makes this the short sleeve shirt to wear when you still need to look put together: the office on a warm day, lunch that turns into dinner, anything at the Races that is not the main enclosure. Part of 20% off Gant in the Summer Sale.

14. Eden Park Short Sleeve Shirt
Pink has been one of Eden Park’s signature colours since the brand’s founding; the pink bow tie logo dates back to the 1987 French Championship final, worn by the players as an act of playful Parisian rebellion. This short sleeve shirt carries that heritage well: a confident colourway executed with the fabric quality the brand is known for, and one that wears beautifully with white chinos, light linen trousers or navy shorts in the sun.
