Shopper I have a similar concern. But i am about 65 kilos and 1.75 m tall. i currently use a gul 3mm full length suit. Should i still go for large ? Im afraid it will be too big for my size. Furthermore large might not be usable if i decide to use this by itself. What size should i go for ? Medium or Large ? I like the option of using this standalone. but i also wanna be able to slip it over my gul without too much difficulty.

JM K I have a medium size scubapro thermal tec steamer 3mm suit. I am 5'7" and weigh 170 lbs. I am planning to wear this pinnacle escape 7mm hooded vest over my scubapro suit. What size do you think I should order? Would large be fine? If the size chart of this product means measurement with naked body, then I should order something at least large or x-large.
