The Cool & Collected Guide: Breathable layers for men who run hot
My partner’s approach to dressing defies all seasonal logic. He will happily wear a long-sleeved Hinsley shirt in 25°C heat, but the second winter arrives, he refuses to wear a heavy coat because he’ll "melt on the commute." His autumn uniform consists of an Editor striped rugby polo shirt over a plain tee, no jacket required, well into freezing temperatures.
Luckily, my job as a Garment Technologist at Percival means I actually understand the textile science behind his madness.
Living with someone who runs perpetually hot has taught me that temperature control isn't about wearing less - it’s about picking the right breathable clothing. If you’re a guy who breaks into a sweat just looking at a heavy wool overcoat, or you’re shopping for a partner who regards central heating as a personal threat, here is your year-round guide to breathable fabrics, smart knits, and easy-off layers.
What is the most breathable fabric?
When looking for the most breathable fabric, the goal is finding textiles that allow air to circulate freely while pulling moisture away from the skin. Synthetic traps; natural fibres breathe.
- Linen: The undisputed heavyweight champion of airflow. Its loose, open weave creates natural ventilation, making it a summer essential.
- Merino Wool: Don't let the word "wool" scare you. Fine-gauge men's merino wool is naturally thermo-regulating. It breathes when you're warm and insulates when you're cold.
- Open-Weave Cotton & Waffle Knit: Standard flat cotton can hold moisture, but textured structures like waffle weave create micro-air pockets that keep fabric off your skin.
- Textured Knits: Knitted looping allows air to pass through far more effectively than tight, flat-woven fabrics.
Cotton, linen or polyester: which is most breathable?
When asking if cotton is breathable or is linen breathable compared to synthetics, natural fibres win every time.
So, is polyester breathable? In short: no. Pure polyester is made from synthetic plastic fibres that trap heat and seal in moisture against your skin. Unless it’s an engineered technical mesh, pure polyester will turn any outfit into a portable sauna.
Linen is by far the most breathable option available thanks to its low thread count and natural stiffness, which prevents it from sticking to your body. Cotton comes in a close second for everyday comfort - especially when woven into textured or open-knit structures.
How to layer clothes without overheating
If you run hot, the golden rule of how to layer clothes isn't adding warmth - it’s creating versatility. You want pieces that come off as quickly as they go on, allowing you to regulate your temperature the second you step indoors or hop on a crowded train.
Read our full guide on how to layer clothes for men for a deep dive into building foolproof outfits.
Lightweight jackets
A heavy, lined overcoat is a recipe for disaster if you run warm. Instead, reach for mens lightweight jackets or unlined overshirts that offer structure without trapping heat. An unlined overshirt or cotton jacket acts as the perfect top layer over a tee or knit, giving you a polished silhouette that you can effortlessly shed when things warm up. Explore our range of versatile overshirts to build your mid-layer lineup.
Breathable waterproofs
Rain protection shouldn't feel like wearing a plastic bag. Finding a truly breathable jacket that keeps the elements out without turning into a sweatbox is the holy grail for guys who run hot.
This is where my partner’s absolute pride and joy comes in: The Sherlock. He wears his Sherlock trench coat with genuine pride all through autumn and winter. Because it’s built from a premium, showerproof fabric that breathes, it offers complete weather protection without heavy insulation. He only needs a single light layer underneath and he stays warm, dry, and comfortable without ever overheating on his commute. Check out our cropped alternative: our brand new Carter cropped trench coat.

Breathable shirts
Standard woven dress shirts offer zero give and trap heat across your chest and back. Upgrading your rotation to men's breathable shirts means embracing textured knits and open weaves.
Swap flat poplin for a knitted t-shirt or an open-knit polo. My partner famously wears his knitted polo shirts right through summer - and as a garment technologist, I completely approve. Because a knitted stitch consists of interlocked loops rather than a tight flat weave, air flows through the fabric constantly. You get the crisp look of long sleeves with built-in air conditioning.
For warmer days, explore our linen shirts or dive into our textured pieces in The Waffle Collection. You can also learn more about why waffle textures keep you cool in our guide exploring the waffle weave fabric.
Accessories for men who run hot
When you can't add heavy clothing layers, men’s accessories become your secret weapon for temperature regulation and seasonal styling.
- Caps: A good cotton cap keeps the sun off your face in summer and tames rain in winter without insulating your core. Browse our range of classic caps.
- Lightweight Scarves: Heavy wool scarves can feel suffocating. Opt for soft merino or lightweight cotton men's scarves that protect your neck from cold winds while letting your body breathe.
- Quarter Zips: A men's quarter zip is a hot-running guy’s best friend. The zip front gives you instant, adjustable ventilation at the neck without having to pull a whole jumper over your head. Discover how to style one in our quarter zip sweater guide, or shop our full collection of quarter zip jumpers.

Winter layering
Mastering winter layering men style when you run hot comes down to strategic fabric choices. You don't need five thick layers to stay warm; you just need the right two or three.
Start with a lightweight, 100% cotton base tee. Add a fine-gauge merino wool knit or a mens quarter zip as your insulator, and top it off with a breathable, showerproof outer layer like The Sherlock. Merino wool naturally manages heat and moisture, while an unlined showerproof coat blocks wind and rain without baking you from the inside out.
