  • Tight design and internal back gasket prevent seepage through zipper.
  • PFC and PTFE free limestone neoprene- more durable, less environmental impact, no toxic hydrophobic coatings.
  • Strategic Stitching seam layout reduces fatigue and maximizes mobility where it matters most.
  • Liquid rubber seams seal the suit while maintaining flexibility.


Bombproof Back Zip

Sturdy YKK bombproof zipper, interior overlapping and a tight exterior seam prevents water from seeping in through the closure. A secure neck flap locks the zipper in place.

Bomber Seams

Stitched, glued, taped and sealed with liquid rubber for seams that are water tight, flexible and durable.

Limestone-Based Neoprene

Neospan S-Foam Neoprene: Industry standard for high-end suits, super soft and stretchy, more durable and less environmental impact than petroleum-based Neoprene and no toxic hydrophobic chemicals.

Strategic Stitching

Stitch pattern designed to allow for maximum range of motion while avoiding stretch points and minimizing chafing.

Holy Knees

Rugged, abrasion resistant BAX material covers knees of all long suits for added protection and durability where it’s needed most.

Bloat Free Drain Holes

Strategically located to drain water and prevent “elephant leg syndrome.”
