Kevin Kiermaier uses the very popular Nike Trout Force Elite 2.0 batting gloves. It would be a little weird to have equipment with an opposing player’s name on it, so guys who wear the gloves, like Kiermaier, have the logo on the wrist changed from “Trout” to “Nike.” Totally understandable.
There are a few places you can find these gloves, but the best color selection that we’ve seen is still on eBay. Most of them are listed for $40-$50.
