Nonporous membranes mated with a light breathable fleece lining give you the ultimate in climate control as well as fluid repellency. The Synchro Jacket was design for use in cold weather hiking or skiing but, it makes a nice cross over into the cycling market. It provides shelter from the harshest element, water. The conduit boasts supreme water repelling capabilities, "Drier living through Chemistry". Mountain Hardwear says that Intermolecular gaps allow water vapor to pass out of the garment from the inside via positive pressure while water is completely repelled on the outside.
What does this all mean?
It means that if you are skiing down a mountain or spinning along the roadways and precipitation happens, the cold waters will run off. But if precipitation doesn't happen, the sweat that you work up will phase out of the garment to keep you as dry as possible. I am the perfect person to test these capabilities because I sweat more then anyone I know. In my trials I would have to say that this jacket has kept me drier then any other I have tried. Several of the rides I took with the Synchro were extremely windy; the wind did not effect my core, which was well protected by the jacket. The Synchro has a cinchable neck, which helps create a comfortable seal around your neck to keep cold drafts out, even in a 40 MPH aero-tuck. The sleeves have a moldable soft lining that creates a form fitting seal to keep the cold from going up your sleeve. All seams and zippers are taped and "welded" to increase water resistance and durability. The end result is a jacket that will deliver on water repelling, longevity and comfort.
Another nice feature of the Synchro is that it has ample pockets. When you are on the road, especially in cold weather there is always a need to stow something. Gloves, energy bars, skullcaps, energy gels, keys, etc., all can be aptly stored away during a ride in one of the many pockets that this jacket has. A very nice touch.
As I stated earlier the Synchro was not specifically design for cycling. But, if Mountain Hardwear wanted to make the jump into cycling specific gear, I have a couple of suggestions. The backside pockets that are only present in cycling jerseys are an absolute must for grabbing something quickly, without stopping. The cut of the jacket is slightly less aerodynamic then I would like. The shoulders, chest and waistline are cut well but, a bit of material could be trimmed out around the stomach. Although the cut of the Synchro allows for good cold weather layering.
