I am riding in a clinic with a BNT in December, It has been a while since I have ridden in a clinic and need some recomendations for clothing. It will most likely be cold so a polo is probably out of the question Thanks for your help!
Could you do a polo over a long sleeved shirt? I did a clinic in December once and put a polo shirt over Under Armour - it was great since I was warm enough but I didn't have to strip off a ton of layers. Otherwise, a polo with a light sweater works pretty well too.
Either Under Armour or a regular turtleneck with a fitted vest over it would be great in cold weather, it keeps you warm and gives you lots of freedom of movement. I also have a very fitted zip up fleece I wore in lessons over Under Armour or turtlenecks.
I've done a couple cold weather clinics and it's a balance between dressing respectfully and not freezing your good bits off. I try for a pair of winter breeches -- you can usually find tan, or if not, I think any clean pair of dark colored breeches is appropriate. I then go with a technical turtleneck and a sweater (usually in a conservative solid color like navy, grey, or black.) If it's really cold I might layer a technical jacket or vest over that. As a rule I try for quiet colors and more traditional breeches.
