## Questions & Answers

**Q: Does this come with the inserts that do if you purchase it directly from manufacturer?**
A: This comes with XL inserts installed.  You can buy other sizes from Wicked Skatewear or S1 directly.

**Q: My son's head is 20.5" this is bang on between mini lifer and small adult size.. Which one should I go for?**
A: I'm 5'6'' with a 22'' dome. I wear the S-ONE Lifer size large. As I understand, each of the lifer helmets comes with TWO ALTERNATIVE anti-microbial foam liners, one thiner than the one in the helmet already, and one thicker than the one in the helmet already helping you to get a better fit. I keep the liner that came in my helmet and it fits perfect! My Answer: Get the S-ONE Lifer size small and use the thicker foam liner if needed. Make sure the helmet front comes down across in line with the brow, you don't want that helmet tipping backwards exposing the forehead. A good indicator is if you twist the helmet from left and right it should lightly grab at the skin on the forehead, adjust the straps so the V terminates just below the earlobe, chin strap snug, not tight, and definitely not loose.

**Q: Does this color have a visor option?**
A: Yes.

**Q: Only tree green matte is astm certified right?**
A: NO all S1 Lifer Certified
