Winter is here, and whether you're spending your afternoons on the training pitch or just chilling out, you're going to need something to keep your ears warm, and you've got to look good doing it. Ireland's rugby players may not be the most fashionable bunch of lads in the world, but they're proven trendsetters in terms of winter hat style over the years.
We've dug through the Sportsfile archives and discovered that there is an astonishing variety of ways that Irish rugby players have worn their winter caps down through the years. Here are our favourite hat-based fashion statements by Irish rugby personalities.
With a traditional fold
Some would say there's only one way to wear a beanie. Brian O'Driscoll would agree. At the height of BOD's bleach-blonde phase in 2004, it's worth noting that he was wearing winter caps on the training pitch. He might have been sporting a magical mullet at the time, but he let this marvelous Canterbury Leinster hat with Leinster's beautiful old harp logo speak for itself.
Barely covering the ears
Heaslip likes his hat pulled back to edge of his forehead - almost to the point to where it loses all functionality. He still looks cool doing it though.
Pulled all the way down
Heaslip and Leo Cullen are as different as chalk and cheese and it's most evident in how they wear hats. Leo pulls his hat down all the way, to cover up those cauliflower ears.
With the top cut out
You've got to stand back and marvel at what Isa Nacewa manages here. He refuses to be stifled by the constraints of fashion and improvises a hat solution that allows his hair to flow and breathe while his head stays warm.
Not even covering the ears
David Humphries loved wearing his winter cap, but it was an act of fashion, not practicality. All he wants is that feeling of cottony warmth around his head. He didn't need anything across his ears.
However your hat twin is doing it
Eddie O'Sullivan and Declan Kidney weren't the greatest of friends when they coached Ireland in the early noughties, but they put those grievances aside in order to attempt coaching hat symmetry. They were hat twins back in 2002 and it definitely put a strain on their relationship.
As a nightcap
Here's another interesting hat style attempted by a coach. Joe Schmidt is a hat man. He wears a baseball camp in warm weather training, and when the chill of winter arrives, he reaches for a stripey number to keep his ears toasty. If Schmidt wanted a nap after training, all he'd need is a pair of longjohns and he could curl up into bed.
