The product: Calm Leisure Ladies' Shaped Equestrian Underwear

The info: British made from natural, breathable bamboo fibre, the underwear has an arched front leg and boxer back. The design is said to keep them in place, while allowing you freedom of movement. In black or white and sizes XS-L, priced £19.95.

Tester Marian Pinches says: "I've worn the briefs for hacking and flatwork and they are very comfortable - there are no seams to cause rubbing and they feel like a second skin. The material is lovely and soft and the pants don't move or slip, and I have been pretty active in them.

"At first glance, they just look like a standard pair of pants, but they are shaped around the inside of the thigh, which improves wearer comfort. The design is effective, but subtle.

"As they are riding pants, I was expecting a bit of padding but they don't have any. While the underwear is a great product, I personally feel the price is on the expensive side."
