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.
Monica s For your hight and weight you fall under the medium size, however I would still order the large for reason you listed above and Pinnacle tends to run on the smaller side, so you should be fine in a large.
