As a rule, there is no deficiency in durability between vegan belt materials and their animal product counterparts. In fact, in many cases, vegan belts greatly outperform belts made of leather. Cork belts, such as the ones by Corkor for example, don’t stain like leather does, and are scratch and moisture resistant. Other belts, like GRIP6’s, have aerospace grade aluminum belt buckles and can withstand up to 250 pounds of outward pressure.
One of the best features of faux leather durability wise is that it does not absorb moisture like real leather does, meaning that maintenance is much easier – just wipe it with a moist cloth to clean it. The only real downsides of faux leather are that it’s more prone to puncture and tear damage and some pleather materials aren’t so great for the environment.
All in all, it’s safe to say that as long as you stick with a reputable brand, a vegan belt will last you quite a while and serve you well. There’s no need to be concerned about their durability.
