I’m 6’3” and weigh 200lbs. I bought this suit to protect me while I removed a Bald-Faced Hornet nest that was built in a bush about chest high. In the process of trying to clip the branches the nest was built on, it became damaged. The hornets swarmed me. They were hitting my suit so hard it sounded like popcorn popping. I just kept working away and threw the nest into a trash can. I walked away and after a couple minutes the hornets left me and flew back to the nest now in the can. I walked back and put a lid on the can, finishing the job without one stinger penetrating the suit; even at the vents. I did wear jeans and a long sleeve t-shirt under the suit. The fit of the suit was great! I bought an XXL and there was room to spare even with the clothes on underneath. Bald-Faced Hornets are VERY aggressive but his suit gave me all the confidence I needed. Saved me $150, too! I didn’t have to hire a pro to remove the nest. If you get one of these, you won’t be disappointed by the protection you get.
