C4 Vertical Up Two-Piece Wetsuit for Freediving and Spearfishing

Vertical Up is a technical two-piece wetsuit specifically designed for freediving and spearfishing, made by C4 with high-quality materials and careful attention to construction details.

Materials and Construction

The wetsuit uses open-cell macrocellular neoprene on the inside and features a stretchy outer lining in Milk Silk, characterized by two-way stretch and excellent abrasion resistance. The neoprene, made from 100% limestone (CR rubber), is TÜV certified for the absence of harmful substances such as phthalates and latex, ensuring safety for both the user and the environment.
