Why Wild Swimmers Wear Woolly Hats - Even in Summer!

Ever wondered why cold water swimmers wear woolly hats?
You’ve probably seen them, the bold bobble hats bobbing above the waves, the flashes of colour in the sea. But have you ever wondered why so many wild swimmers wear woolly hats, even when the sun’s out?
It’s not just a style choice (though let’s be honest, they do look cool in photos). There’s a very good reason behind this cold-water ritual….and it all comes down to warmth, comfort and a little bit of common sense.
Why Your Head Matters in Cold Water
When you swim in cold water, you lose heat fast and one of the quickest places to lose it from is your head. A woolly hat acts like a thermal barrier, keeping the chill at bay so you can enjoy your dip for longer and recover faster afterwards.
Wearing a hat helps prevent that intense post-swim “afterdrop” feeling, where your body temperature keeps dropping even after you’ve left the water. It’s a small thing that makes a big difference.
Woolly Hats vs. Swim Caps - What’s the Difference?
Swim caps are great in the pool or for serious swimmers and triathletes. But out in the wild, in sea lochs, tidal pools and chilly beaches a woolly hat is the real hero! It’s warm, it’s breathable and you can put it on before and after your dip without faffing around. Plus, it gives fellow swimmers an easy way to spot you in the water….extra points for visibility AND style.
