Horze, Ovation, and TuffRider all make awesome fleece lined winter breeches that are under $60.00. I also like the Kerrits and Irideon winter breeches but the weight and quality isn’t much better than the first three I mentioned. If I need to be outside in the wind I’ll wear my old full chaps because I still haven’t found anything better.
For winter riding boots I have the Mountain Horse Stella Polaris and really love them. I’m going on 4 years with the same pair and they’re holding up really well. I just spray them down with a hose to keep them clean.
I have the SSG 10 below gloves but find they’re so warm they make my hands sweat when riding inside. They’re amazing for all around outdoor gloves though. I also have a pair of SSG winter pebble grip gloves that I love for the indoor arena. They’re cheap, light, and very warm but not good for barn chores because they soak up water like a sponge.
As for tops, I do lots of layers that consist of sweaters, vests, and fleece quarter zips from Goodwill because I always ruin them. I do love Under Armour cold gear as base layers.
The biggest thing that has saved me during the winter is changing into dry clothes after I ride. If I don’t that little bit of sweat will give me a chill for the whole day. Even something simple like taking off a cami under my top makes a huge difference.
