Excellent suit that is really dry !!

By Michael Shepherd on 16 Mar. 2022

Excellent service from Cara, both by phone and text, re my new drysuit. Suit itself fits exactly as their sizing chart says. It is of a high quality, and perhaps to the point - is DRY !!!

Bought an HID Cortex drysuit reduced…

By David P. on 11 Apr. 2022

Bought an HID Cortex drysuit reduced from £945 TO £575. Fantastic suit, ND adjusted the leg length free of charge and the alteration was done and suit posted to me in super quick time. Great service all round. Many thanks. The suit looks and feels like a much more expensive suit than what I paid and has been admired by several of my buddies
