Ian C.wrote a review of Kask Protone Helmet on December 15, 2018
Familiarity: I returned this product before using it
Helmet itself is great quality. Issues are more with Competitive Cyclist:
1. Size up if you're near the limit of the size guide. I measured within medium using the size guide provided here--too small to get on.
2. The item I received had clearly been opened before - helmet wasn't properly seated in the box and no manuals or Kask swag that I could see. Not a huge deal for something like a helmet, but disappointing in conjunction with the other issues.
3. The CC 50%+ off sale price is actually more expensive than buying from Kask directly. The item is manufacturer discounted. You can even get it at amazon, shipped much faster, with free returns. That's what I ended up doing to get the larger size (and the item I received from Kask via amazon was new).
4. I returned this item to Competitive Cyclist. Have not received confirmation of refund. Had to pay return shipping - again, not the end of the world, just FYI as you're shopping.
