Comfy and cosy they may be when snuggled up on the settee.
But as dozens of daring dookers learned, the onesie is no match for the might of the North Sea on January 1.
At Arbroath and Carnoustie, onesie-wearing paddlers joined superheroes, comic characters, nuns and those just simply daft enough to see in 2014 with a dash and splash of a decidedly chilly variety.
Mother Nature turned up in windswept grey, first-footing with mighty waves which crashed over the sea defences of the two Angus towns catching out some non-dookers who ended up with a soaking nonetheless.
But the cold conditions didn’t put off either spectators or those willing to take the plunge and organisers of each event said they were delighted with their best ever response.
Arbroath’s dook was held at noon, with a minor, weather-forced switch from the lifeboat shed to the new slip just a couple of hundred yards west of the station.Photo gallery: Arbroath New Year DookThe event raises money for Cancer Research UK and organiser Alana Loudon said the turnout of 159 dookers was more than double last year.
She praised the local lifeboat crew for the vital role they played, guiding dookers into the sea in groups to ensure their safety among the waves of the high tide, before rounding off the event by taking to the water in her pirate costume.
A couple of hours later, the fun and frolics switched to the sands close to Carnoustie Rugby Club for the now traditional start to the new year.
Carnoustie player Lewis Thoms had the honour of kicking a rugby ball into the sea as his reward for being the first to reach the 2013 punt, and the chase was won by Dublin visitor Philip Darcy.
“I’ve never done a dook before, but I got challenged to do it last night and was determined to get to the ball first,” said delighted 32-year-old Philip, who plans to be back in Angus in 2015 to fulfil his starter’s role.
