If it's race day and the rain is coming down in buckets, you obviously need to stay dry to win. Instead of throwing on a flappy jacket, gain an advantage over the pack with the Castelli Gabba WS Short Sleeve Jersey. The Gabba WS jersey was designed hand-in-hand with the Cervelo Test Team and the Garmin-Barracuda cycling team to create an edge against the brutal weather of the spring classics. The Gabba WS fits and feels like an aero jersey, but with all of the weather protection of a rain jacket.The Castelli Gabba WS Jersey is a rain-specific version of the Castelli Aero Race Jersey. In the development stage, Castelli knew that no material existed to meet Cervelo Test Team's demands for a rainproof race jersey, so a partnership was formed with W.L. Gore to create the new WindStopper X-Lite Plus fabric. The new four-way stretch fabric allowed the construction of the form-fitting, windproof, and breathable rainproof jersey that we have today. For further rain protection, Castelli included a storm flap off the rear jersey panel to protect you from wheel spray, and the three rear pockets feature eyelets for water drainage. To add extra comfort, Nanoflex inserts under the arms and zippered chest vents allow controlled temperature regulation and a better fit. Castelli finished off the Gabba with a silicone gripper at the waistband to control jersey creep and rear reflective tabs for enhanced visibility in gloomy conditions. The end result of all this innovation is a jersey that Roger Hammond calls the best jersey he's ever worn. You can't go wrong with that.The Castelli Gabba WS Short Sleeve Jersey is available in six sizes from Small to XXX-Large and in the colors Black/reflective silver and Yellow Fluorescent/reflective silver.
Weaknesses: A little on the expensive side but you get what you pay for.
I now own two of these. The bright yellow one makes me visible on cloudy and foggy days. The black one just looks cool. This jersey is warm. I wear one base layer when the temp is in the low 40's. I add a second base layer when the temp gets in the 30's. I paired it with thick arm warmers and two base layers and was comfortable at 32 degrees. The sleeves are slightly longer than a standard short sleeved jersey so there is good overlap with the arm warmers.The other thing is that it is form fitting. The thing I don't like about jackets in the winter is they are so bulky and catch the wind. Not so with this. Castelli runs a little small. I am 6'0', 155lbs and the large fits nice and snug. I normally wear a medium.
