Slice through wind and rain.

Castelli left the days of ill-fitting, poorly functioning winter cycling clothing behind long ago, and the brand now takes full advantage of the wonders of modern technology to create clothing that barely resembles its ancestors. The Trasparente 2 Jersey may have evolved over time from various boxy, stiff windbreakers, but you'd barely be able to tell by looking at it. All sleek darting and subtle materials, the jersey provides effective protection in tough cold-weather conditions while retaining the impeccable fit and comfort that Castelli is known for.

The Trasparente 2 features stretchy Windstopper X-Lite panels on the chest and shoulders works to repel rain and block icy blasts of wind without feeling bulky, while Castelli's Warmer fabric is used on the back of the Trasparente to enhance its breathability, facilitating moisture transfer and providing insulation for ride temperatures ranging from 50-64 degrees Fahrenheit. Never neglecting the simple details that make a jersey truly functional, Castelli includes a full YKK Camlock zipper as well as an elastic gripper on the bottom hem of the jersey to hold it in place, while three rear pockets with reflective accents give you space to store ride essentials and help increase your visibility in low light conditions.

In terms of fit, expect forward-oriented sleeves and an abbreviated fit in the chest compared to similar offerings from other manufacturers. This makes Castelli clothing feel a little tight across the chest while you're standing, but perfectly adapted to your body once you're stretched out on the bike. It sits close to your chest and stomach instead of hanging down, and the more forgiving stretch of Windstopper X-Lite means that it moves with you rather than restricting you.

Perfect Fall into Winter

  • Familiarity: I've used it several times
  • Fit: True to size

I am *very* impressed with the Trasparente 2 from Castelli. I've long struggled with layering for riding in Utah's fall as my rides often are climbing up a canyon then descending. The Trasparente has been the perfect jersey to keep me comfortable in that ever-tricky temperature range of late fall.

The windstopper panels on the jersey keep the fit lovely with a nice silhouette. The sleeves, cut for a forward riding position, avoid the all-too-common bunching of fabric at the shoulders of other jerseys. The 3 pockets in back are deep enough to hold all those snacks for winter base miles, while being easy to reach into while riding.

The windstopper fabric makes it warmer and sturdier than other jerseys--more of a hybrid between jersey and jacket like Castelli's Gabba, but thinner. This jersey is perfect for 40-55* or so. Castelli ranks it up to 65*, but I think it would be too warm for me at that temperature.

I'm 5'6" 140# and prefer the race fit of the medium. I would recommend going up a size if you prefer a club or looser fit

Bought a second one

I agree with the other reviewer, perfect in the 45-60 degree range. On cooler mornings I'll add a wool baselayer. It does a wonderful job blocking the wind on downhill runs so you can avoid wearing a vest. Highly recommend this as a core part of your cycling wardrobe.

Fits great, good for 50-60 degree rides

I got the jersey in white and it fits well and looks good. Riding in New England with the wind can be chilly and I get cold easily. For 60 degrees I was okay with nothing underneath but for 50 degrees I had a short sleeved base layer which was good for a chilly start but a quick warm up.
