The Salvimar 3mm HT Weld System Gloves have been designed specifically for freediving and spearfishing in colder waters. The Salvimar 3mm HT Weld System Gloves feature a durable and reinforced palm with a special HexaPU lining. This extra strong lining on the palms is to avoid wear and tear on this most vital part of your dive gloves as well as to provide a sure fire grip and reliability when you need it most hunting. Thanks to their unique double lined design the Salvimar 3mm HT Weld System Gloves are not only very warm but also provide the spearo with great dexterity and flexibility which does not hinder speargun trigger sensitivity or affect the "feel" required when reaching for your next cray. In short, these gloves are phenomenal.
