Jill Layfieldwrote a review of Julbo Blast Spectron 3+ Sunglasses on September 3, 2015
Familiarity: I've put it through the wringer
I use these for running and mountain-biking. I got them in blue, and they look pretty slick. They work as both casual and sports shades. Good balance between wind and sun protection, and ventilation. Nice and light. Very comfortable, with not too tight a fit (sunglasses that squeeze my head tend to give me headaches). Usual top quality Julbo optics. The only downside for me was that the arms are completely straight, and I found that the glasses would eventually start to slide down my nose. Spent a few minutes with a hairdryer to put a slight bend in the arms, and problem solved.
