## Questions & Answers

**Q: If this doesn't fit properly, is it returnable?**
A: I don’t know. I measured my head against the chart they provided and when the helmet arrived, it fit. A little snug, but they’re supposed to be snug.

**Q: Is the chin guard infused with styrofoam for protection?**
A: No, its open for ventilation.

**Q: Is the tinted visor dark enough to protect from the strong direct morning sunlight?**
A: This really depends on you, where you live... etc. 
My eyes are very light sensitive and the mid day sun, in Missouri, during the summer KILLS me. So for me under those circumstances it's not enough. But if I forget my sun glasses at home, the dropdown tinted visor is pretty good. I'd say it's a medium to lightly tinted visor.  YMMV

**Q: Is the tinted visor dark enough to protect from the strong direct morning sunlight?**
A: I bought this helmet for a trip in Ecuador. The visor was tinted enough for all day sun. The problem is getting the visor to come down with one hand. It feels like it gets stuck in the up position. I ended up wearing sunglasses for most of the trip because the visor is basically unusable.
