From Sugoi's Website:
"Our modern lives force us outdoors to commute and train in the dark, making it essential to be visible at night.
At SUGOi, we specialize in apparel that allows you to perform when the elements don’t cooperate, including darkness. With the Zap, SUGOI opens the door to a new era of visual technology. Thanks to our Zap fabric, you don’t have to worry about staying safe as the days turn into long nights. Zap will keep you ultra-visible in low light conditions.
The secret lies within our Zap Woven fabric. Micro-glass beads applied to the woven fabric shell provide explosive, full-garment illumination plus water protection when conditions get ugly. When entirely constructed with Zap fabric, reflectivity is no longer restricted to small patches. An entire garment can become your source of visibility. And with Zap accessories like helmet and shoe covers, you can light up the night from head to toe.
Best of all, Zap only reveals its hidden power when struck by artificial light, allowing color and style to play the lead role in the daytime."
Bottom Line: Sugoi's ZAP technology is immediately visible in the dark when light hits it - regardless of the base color, any part of the garment with ZAP technology turns a bright reflective white!
The best part is that ZAP can be applied to just about every fabric in Sugoi's line up - whether it's a waterproof, breathable jacket (like the one above), or to porous lycra stretch tights...ZAP will lay in wait until a car headlight hits it to let drivers and other road users know you're there.
A couple of our guys here in the shop have been wearing Sugoi's ZAP Waterproof Commute Pants for a few weeks now, and the reviews have been good. The pants are completely seam-sealed with a reinforced crotch and seat, making the well suited for road or mountain riding. The cut is loose, but not baggy, preventing the "Stay Puft" effect when screaming down a hill. Breathability is excellent, as are the sizing features (elastic waist with snap closure and zip fly, with velcro cinch/ankle snap cinches). The only thing we noted was that it may be easy to over-layer for those cold morning rides...the pants feel thin, but their thermal efficiency is pretty excellent. Wearing a thin tight under the pants has kept us comfortable riding in wet conditions as low as 40 degrees. At 55-60 degrees, you may want to ditch the tights for just a pair of shorts with knee warmers. With regards to water resistance, the pants have held up very well, including a prolonged gravel ride on Green Mountain in a 2 1/2 downpour. Water did eventually find it's way through at points, but the 20k/2.5 Layer waterproofing used on these pants is legitimate...if you are looking for a pant to keep you dry on your ride in to work, or for that weekend training ride, these are it!
