This is easily the best Semidry suit I have ever worn!!!

By Ryan Hunnisett (via Instagram) on 27 Oct. 2023

This is easily the best Semidry suit I have ever worn!!! It's super strechy, easy to don and doff, affordable and most of all - it is exceptionally warm! @northerndiveruk you have truly outdone yourselves with this suit! The 5.5mm long John was warm enough to wear alone during the summer months and yet when layered with the 6.5mm shortie over the top, I was still able to dive in my local quarry comfortably, which has a bottom temperature of 7'C!!! If you don't believe me then just check out the pics
