I have 2 of the full stingstopper suits in the olive color. I do hornet/yellowjacket removals (not bees), and these have kept me sting free for 3 years. I got this jacket version for smaller less dangerous nests etc. Just something quick I can throw on. It's just as well made as the full suit. For reference I am 5'11" 185 lbs and the large fits me perfectly!
