Heat-resistant gloves are a must for sublimation. The temperature necessary for the sublimation process can be upwards of 400+ F, and the items coming out are nearly as hot. Any heat-resistant gloves or fabric gloves, even pot holders one would use for their oven at home, can provide appropriate protection from the heat press and substrate. I know for our customers, the Ove Glove (or similar, non-branded gloves) is a popular choice.
