How we calculate scores →About this gear
The 65 combines a 6 mm torso with 5 mm arms and legs, a back zipper and Thermal Plush torso lining. Glued and blind-stitched seams, glide-skin wrist seals and a shaped adjustable collar aim to reduce water exchange. Reinforced seat, leg and knee areas give it a more substantial build than a thin holiday suit.
Consider before buying
Try the wrist seals and back-zip reach before committing to a size. This is a semidry wetsuit, so fit and water exchange still matter. BiG Scuba describes comfortable dives while wearing an additional Short John underneath; that account does not establish the suit’s performance alone or a universal temperature limit.
Our take
Choose the 65 if you prefer a back-entry suit with a thicker torso and integrated lining. Compare Hollis Neotek 4/3 for a different thickness, front entry and attached hood. Manufacturer-hosted testimonials and the unscored external account provide context, but no eligible overall numeric grade was verified.

The contributors describe using the 65 with a Short John layer. Their comfort report concerns that personal combination, not a tested temperature limit or an overall numeric rating.
Source and scoring details
Exact 65 suit with additional layering. The separate 3 mm shorty mention is not evidence for the current 2.5 mm Shortie.
Brand feature page; commercial relationship not verified. Personal experience is limited to the stated layered setup.
