Designed for dives in water temperatures between 7°C and 14°C, it can be adapted for colder conditions with appropriate base layers, making it suitable for technical diving, wreck exploration, and long cave dives. Key features include three pockets, water-resistant cuffs, tapes to supply air to dry gloves, a two-way main zipper, an elastic windproof waist gusset, shoulder gussets for freedom of movement, and wide elastic ankle bands to prevent ride-up.
