## Questions & Answers

**Q: medium fits 34 waist?**
A: im a 33x30 and I typically wear large anymore for comfort because the mediums are too tight fitting in the crotch area.

**Q: What does " low output" mean?**
A: Output level refers to exertion while wearing Carhartt base layer, so "low output" means you are not really exerting yourself. Base layer for “high output level” means it’s generally best worn for high-aerobic activities, keeping in mind that this also intersects with temperature.

**Q: Do the pants have a working fly or not?**
A: Yes, Carhartt Men's Base Force Midweight Classic bottoms have a working fly (Style# MBL115). Carhartt Men's Base Force base layer bottoms with contoured front with fly include the following styles sold on Amazon: MBL121 Heavyweight Poly-Wool, MBL112-Heavyweight, MBL149-100% Cotton Midweight Classic, MBL106-Midweight Tech, MBL103-Lightweight.

**Q: What size do you recommend for 6’4” with a 36 waist ?**
A: XL
