Foal equestrian! They're a sister brand to Arista, and they are absolutely amazing! I bought mine for around $100canadian and it's wonderful quality! Zippered pockets (but well hidden), zipper and four buttons at the front and the back unzips to have the option of have a silky material with a pop of colour (mine is grey with pink accents at the back; I used it for hunters (with the pink hidden), and jumpers!) I have since quit jumping and use it for dressage!
Sometimes they have super sales on their website! You should definitely check them out 😊
Kerrits is relatively cheap I think
