On test: Pearl Izumi Vector Jersey, April 20, 2006

Adaptable cool weather protection

James Huang continues with his winter clothing tests with the adaptable Vector Jersey from Pearl Izumi.

Pearl Izumi Vector

At first glance, Pearl Izumi's Vector Jersey almost looks more like a light jacket. However, it's actually a versatile long-sleeved jersey with a moderately insulative brushed Kodiak Ultrasensor back coupled with a contrasting windproof, water-resistant, and insulative AmFib front. A full-length windflap-backed zipper and medium-height collar add further wind protection. Pearl Izumi's attention to detail that was evident in the Barrier Jacket carries over to the Vector Jersey with its lockable zipper pull and 'zipper garage' just below the neck that prevents inadvertent contact with your skin on cold days.

In addition to the full-length main zipper, flexible temperature control is also provided by supplemental zippered vents located on either side of the chest. Two decently-sized pockets plus an additional small zippered pocket decorate the extended rear of the Vector Jersey and a well-distributed assortment of reflective material provides an appreciable amount of low-light visibility.

Is it spring yet?

As its appearance suggests, the Vector Jersey is rather heavy-duty and is well-suited for cold rides. By itself, it's not quite enough when the mercury hits the freezing mark, but it is just right if the air is about 10-15°F warmer, particularly if the sun is shining. The full-length zipper and extra side vents make for very effective temperature regulation and are particularly welcome in slower sections out in the woods or during extended climbs. As the needle passes 50°F, though, I would likely reach for something a bit lighter as the hefty insulation and thoroughly effective AmFib front can make things a bit too warm and fuzzy depending on your personal thermometer. I didn't have the 'opportunity' to test the jersey in truly ugly conditions, but the water-resistance of the AmFib front would likely be quite welcome in a cold rain.

Ha ha, wind

Pearl Izumi incorporates the handy 'zipper garage'

Pearl Izumi uses its 'Semi-Form Fit' cut for the Vector Jersey that provides a bit more room for movement yet retains an athletic fit. Unlike the Barrier Jacket, though, the fit around the rear of the shoulders was snug but not restrictive, and likely benefited from the extra stretchiness of the Vector fabric (the Barrier has a large non-stretch reflective stripe that runs across the back). Interestingly, the fit was more like what I would have expected from a 'Form Fit' pattern as was intended for the Barrier. Again, though, much of this issue is likely more due to my decidedly atypical (for a cyclist, anyway) upper build so it may not be an issue for you. Regardless, the folks in Broomfield acknowledged this issue as well, and production models sport a revised fit with more room out back as compared to my early version. Trial fits on a later production garment confirmed that the issue has been resolved. As with any article of clothing, though, it is always advisable to try on the garment before purchase if at all possible.

All in all, the Vector Jersey is certainly a handy piece of clothing to have in the stable offering comfort over a fairly broad range of conditions. This versatility ensures the jersey will see a fair bit of use, and the relatively conservative styling should still look pretty fresh for a few years.
