Wanted a thin wetsuit for an upcoming dive in Qatar water temp was 28°C at 20m!! Went for this and got in touch with Mikes for size recommendations, I'm 6 foot and 41inch chest and went for the Medium. Fits like a gloves, really nice material, well made and good zip etc Kept me warm, slips on and off easily and would work as an extra layer under a thicker suit. Handy layer for stopping scrapes and stings, and protecting pasty transparent Scottish guys in 30 degree sun Weighs next to nothing and dries quick, great for travel Only downside is no knee pads but it's a minor gripe and I feel like this is great value for money.
