The Good: "Neutral" styling blends in at races or on the trail. Comfortable and well-ventilated. Fit is easy to adjust with one hand.
The Bad: Chin strap seems to loosen over time.
I picked up the Giro Phase in black back in 2010 and it has served me well since then. It's not as expensive as a lighter or flashier lid, but it does the job just as well and still looks pretty good. The dial that adjusts the fit is quick and easy to use with gloves and while riding, and I can quickly snug it down with just one hand. I've used this helmet for cross-country riding and racing and trail riding, and I've even taken the visor off and used it for road racing. It has an unremarkable style which fits in anywhere. If you want your helmet to stand out in a crowd, look elsewhere, but otherwise this is a great choice for the trail/XC segment. The one complaint I have is that the chin strap seems to slowly work itself loose over time. I've noticed this happening consistently since I've had the helmet, but it's so gradual that it's never been a serious issue. When it eventually comes time to replace my current helmet, the Phase will be my first choice.
