Mystic Motion Fullsuit 5/3mm Fzip 2026

The Mystic Motion Fullsuit 5/3mm Fzip is a men's 5/3 mm full wetsuit with a front zip. The promise is simple: quality, warmth and flexibility at an unbeatable price. Fleece and high-stretch XTR inner lining, 3D design with virtual simulation, less water flushing and a pre-shaped entry. The 4-way stretch Hex-tech knee pads add durability and the internal tape keeps cold water out of the critical areas.

Who it's for

• Anyone who wants quality, warmth and flexibility without overspending.
• Winter and cold-water sessions.

Features

• 5/3 mm thickness: 5 mm on the torso and 3 mm on the arms and legs.
• Waterproof stretch tape on 50% of the seams: in the critical areas, where most water gets in.
• GBS seams (glued and blind-stitched): the needle doesn't go all the way through the neoprene, so the seam is watertight and warmer.
• YKK front zip: chest entry, leaving the back free for more stretch and a better seal.
• Glideskin neck: smooth, stretchy skin that seals the neck without chafing.
• Aquabarrier: internal barrier at the entry that stops water getting through.
• Hex-tech knee pads: 4-way stretch and abrasion-resistant.
• Non-slip cuffs and ankles: they stay in place and limit water entry.
• Key pocket 2.0: loop with mini buckle.
• Aquaflush 2.0: Mystic's system to keep cold water out and drain any water that gets into the suit.
• MX3 neoprene.
• Fox Fleece lining on the chest, back and lower body.

Which size to choose

Official Mystic size chart. If you're between two sizes, go by chest and waist rather than height. Sizes ending in S and T (MS, MT, LS, LT…) are shorter (S) or taller (T) versions of the base size, with the same chest and waist. More help in our guide to choosing the perfect wetsuit.

Frequently asked questions

What does 5/3 mm mean?

The first number is the neoprene thickness on the torso (5 mm) and the second on the arms and legs (3 mm): more thickness where you need warmth and less where you need to move.

What's the advantage of a front zip?

Chest entry leaves the back free, so the suit stretches more across the shoulders and back and seals the neck better, with less water getting in than with a back zip.

What water temperature is it for?

Mystic doesn't give a specific temperature. As a general guide, a 5/3 mm full wetsuit works well in water of about 9 to 14 °C, although it depends a lot on the wind and how much you feel the cold. Our wetsuit guide has the full explanation.
