They normally use their riding equipment to protect themselves from a nasty fall.
But when this group of women from a hunting group decided to bare all for a naked calendar, it wasn't their bones which needed protecting.Click to see more photos
Instead, they used helmets, saddles and other hunting paraphernalia to protect their modesty
Over a dozen ladies aged from 18 to 65 were pictured in the Tynedale Hunt 2013 calendar which is being sold to raise money for the Great North Air Ambulance.
The idea of baring it all for a good cause came from Claire Angus who is head groom for the Northumberland-based hunt
She disrobed alongside 14 other volunteers for the photographs, including supporters' club committee chairman Val Armstrong and hunt secretary Catherine Leech.
Ms Angus said: 'It was amazing how much we were chatting to each other and the experience brought us all closer together, even though it was really cold
'I thought it was a fantastic fundraising idea, especially for the air ambulance which is relied on a lot for horse events and our hunt.'
The photographs were taken by hunt member Verity Johnson, showing members striking a pose alongside horses and hounds, in scenes from the Hunt Tea, Hay Shed, Tack Room and The Hunt Ball.
Verity said: 'The ladies were a bit daunted at first but once the gowns were off, it was a good giggle.
'There was one shoot we did where the ladies were on bikes and the hounds were meant to follow, but they wouldn't, so we ended up getting one of the huntsmen to lead them on - it was a scream
'Everyone got to know each other and formed even stronger friendships because they'd had such a bizarre experience together.
'Frank Houghton-Brown, the joint master of the Tynedale Hunt, has been so supportive of us and what we are doing.'
So far 140 calendars have been sold in just four days and the Tynedale Hunt Calendar is now on sale for £13.95.
