Service from STG: Shipping was quick; ordered on the 17th and received on the 19th.
Fit/sizing - Wearing size medium; felt overly tight during "home" usage, but went away during initial ride. Liner still feels "off" near left ear and requires a few quick adjustment every time, but this could be the liner still breaking in. Helmet is comfort while riding though.
Function - Face shield clarity is good and having a clear and dark shield is great. Air flow is awesome and vents well. Noise level is good; should be noted that I wear earplugs. Airfit system is a nice addition; loose for moseying around town and comfort, and pumped up tighter for spirited riding.
Quality/finish - Finishing is better than expected from sub $300 helmet. There are a few fitment quirks; things not 100% lined up which are only noticeable if you really search for them.
Conclusion: Overall, I am very happy with my purchase and the quick shipping from STG. This is a lot of helmet for the money. Sidenote: Had the unfortunate opportunity to test its crash protection a few days ago and it held up great. Only superficial damage to chin guard and would still function and protect fine.
