No, you can not trade these gloves. They are an untradeable item. Luckily, there is a way to get your money back that you invested in the hydra leather you need to make your gloves. You just need to go back to the vault and the machinery where you have used the barrows gloves, hydra leather, and hammer to make the gloves.  Bring your ferocious gloves and a hammer. Use the gloves on the machine while the hammer is in your inventory. This way, you will get back the barrows gloves and the hydra leather. The hydra leather can be sold to other players. That is how you can make your money back. You can not buy or sell the ferocious gloves directly, and you will always have to assemble or disassemble the gloves.
