Question: For a 145 lbs 5 ft 8 male, will medium size fit?
Document: Its comfortable and sized correctly, you DONT need to buy a bigger size. Has pockets, good if you are doing outdoor adventures. Its reflective so easier to find you in case anything happens. It has decent buoyancy, if it was a bit better I would have given 5 stars.
I am not a clothing expert, but I would estimate this vest to be undersized for anyone over a large. My son (6', 175 lbs) says  it is comfortable for him and the collar will help with warmth on a chilly morning.
good quality floatation vest nice size for the grandkids - safety is a good thing - every little bit helps
Good vest, but definitely runs small. Cant zip it up. Otherwise not a bad value, and functional.I would buy again, but larger size.
size is accurate and color is correct and nice. Material is heavy woven nylon that appears strong. Very happy with jacket overall and the padded collar is a nice touch
Purchased this life vest as spare on my boat. It's great item specially for this price. Size is correct. But will recommend to get one size larger size if you want to put it on your thick jacket in winter.
I think the sizes are too small you better order at least 2 size more than the size you using . If u r large size try to choose xxl and this one is not adjustable :(((( but just good matrial.
I bought the small for my wife and the youth size for my son. This turns out to be very light and comfortable. The padding around the neck is a nice touch.As for sizing, it is a little smaller than I imagined, but still fits.
I use this vest for kayaking. I thought it would be a little less bulky, but for the price it's not bad. The description made it sound like the size was an adult small, but the tag on the vest said it's a men's small. I would like to have known that before I placed the order but it still fits.
Make sure you obtain the correct size. Measure your chest and then use the sizing chart found at  http://www.onyxoutdoor.com/product/175502/866-0034/_/Pro_Caster_VestWhen ordering take into account any bulky clothing you may wear.Tip: I did not have a cloth tape so I used a rope and a ruler.
Answer: no
