Is this suitable for a male 6 foot 2 and 120kg ?
I am slightly shorter than you and 246 lbs. I am using the Scubapro - it fits snug and feels very secure on me. My wife uses the Black Snorkel vest. I think it is fine, although it does not seem as well constructed. I think it is fine as a snorkel vest - it wil keep you lateral in the water and not bobbing like a life vest would. Based upon my wife's size, I would go for XL for sure. I am not sure of your chest size, but you might find it tight when fully inflated.
Yes, I think so. I am 5'10" and weigh 260 lbs. I thought it fit well and worked great!
Yes, it is suitable for a male of that size. My husband used the XL size (he is around the same weight), but both sizes available would have worked just fine!
It should work - I am 6'2, 220 lbs. and it works fine. I use it when spearfishing in rough seas, and it gives me some assistance when I need to take a breather, but it should definitely not be used as a personal flotation device/life jacket.
I am 6ft 200lbs it works very well.
