REV'IT! Alaska GTX Glove
The fitting shape of the Dirt glove and the Alaska glove are quite similar. If you were going to wear the Alaska gloves without your heated liners, I would recommend the same size, XXL. Putting a glove liner on underneath will likely require you to go up one size to XYL. I have noticed the material used in the glove liners doesn't move smoothly against the liner of the glove and cause bunching if your (outer) glove is too snug. I just tested with my REV'IT! Tempest gloves and a Powerlet Heated glove liner and confirmed I would need to go up one size in order to accommodate the heated liner.
