## Questions & Answers

**Q: Anyone poop through their flap?**
A: No. I flap through my poop.

**Q: I am 6'5" tall and 315lbs. What size should I order?**
A: I am 6'4" tall and 250lbs. and I wear the X-Large/Tall and I'm big around the middle. I purchased it a few months ago and have worn it twice. The union suit still fits after being washed, but it is tight enough on me that I would recommend purchasing the 2X-Large/Tall. Hope that helps.

**Q: I’m 6’2” 140 pounds and skinny what’s the best size?**
A: I would go to the Carhartt website and look at the size chart that is there.

**Q: Could this be worn in warmer weather or is it too warm?**
A: too warm
