The Wells Lamont × Phil Casabon Collab Mittens are made to withstand harsh winter storms without failing when you need them most. Their full leather exterior is crafted with HydraHyde® waterproof and breathable leather, which is specially treated to stay storm resistant as long as you need it. Plus their durable shell won't break down against abrasions or punctures, so brushing a tree or doing a tricky edge grab is the least of your worries.
