## Questions & Answers

**Q: Going to lapland in march. temperature is supposed to be around of -6 celsius (21f). will these be enough as a first layer with ski pants on top?**
A: I bought these to go to Alaska in April.  I have worn them under jeans and leathers to ride on a motorcycle in January when it was in the mid-upper 30's F and they were a wonderful base layer.  BTW, I bought and returned 4 other brands of long underwear/ base layer sets, and Herobiker brand was THE BEST.  I ended up buying 2 sets.

**Q: Where are these made?**
A: China

**Q: the waist size for small?**
A: Seems true to size.  Very comfortable, form fitting and warm.  Perfect base layer.

**Q: Are the bottoms material mate or bright on the outside?**
A: They are bright
