Julio Rodríguez wears Under Armour Epic batting gloves. The Epic series is popular among players that use UA gear. They feature Cabretta leather that provides extra strength and prevents finger twisting while swinging the bat.
You only have a few options if you want to get your hands on these batting gloves. Under Armour has them on their website for $50, but only in black and white. You can also check out eBay for some additional colorways.
