Sideral Man C4 One-Piece Wetsuit in Neoprene Glide Skin

The Sideral Man is a one-piece wetsuit made from neoprene glide skin, a material known for its high compression resistance and excellent elastic recovery. These properties ensure a perfect fit and good thermal insulation during freediving and spearfishing.

Design and Comfort

The wetsuit features a pre-shaped cut with a reduced number of internal seams, helping maintain elasticity and ensuring excellent comfort during underwater movement. The cut is designed to promote freedom of movement during finning and spearfishing operations.

Technical Details

• Thickness: 2.0 mm, balanced to provide flexibility and thermal protection during medium-depth dives.
• The sleeves feature multiple bar tacks at the wrists, allowing the diver to make custom cuts without the risk of seam failure or material deterioration.
• Available in 6 sizes (0, 1, 2, 3, 4 and 5), to suit different body shapes while ensuring a close, functional fit.

Materials and Certifications

The neoprene used is certified completely free from harmful substances such as phthalates and latex, ensuring safety for both the user and the marine environment. The neoprene rubber also provides superior mechanical resistance, essential for freediving and spearfishing activities.

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.
