Sinergia Full-Zip Long-Sleeve Jersey

Short days often call for long sleeves if you want to stay warm in the cooler days of fall and spring. Blending warmth, breathability, and a comfortable fit, the Sinergia Full-Zip Long-Sleeve Jersey extends your riding season with Classic Castelli style, whether it's worn as a standalone jersey or as a mid-layer under a heavy duty winter jacket.

It's constructed from Castelli's Warmer fabric, which is soft and fleecy on the inside for next-to-skin comfort, while proving the technical properties you expect from a performance long-sleeve jersey. The thermal material is an effective insulator, but also actively moves moisture to the outside of the garment for quick evaporation during more intense efforts, avoiding clamminess when it's cold and preventing overheating should temps rise.

The form-fitting Sinergia Jersey is anatomically cut for the cycling position, reducing drag while remaining stretchy to ensure mobility as you transition in and out of the saddle. Three rear pockets store the supplies you need for long and short rides alike, while reflective inserts help with low-light safety.

  • A jersey for the cooler days of fall and spring
  • Thermal fabric stays warm with fleecy next-to-skin comfort
  • Jersey wicks moisture to keep you dry during hard efforts
  • Form-fitting cut is designed for performance and mobility
  • Three rear pockets for haul food, tubes, and extra layers
  • Reflective insets on front and back improve low-light visibility

Not for me

  • Familiarity: I returned this product before using it
  • Fit: Runs small
  • Size Bought: XL

It was too bad; I really wanted to like it. But it was sized very small, and the color described as "brilliant pink" was more of a coral color.

Nice Multi-Season Jersey

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs small

This jersey works well as both a jersey and a jacket. I am able to layer well under this if its between 30-40 degrees outside without feeling too bulky. You can wear a thinner base layer if it is still cold but not too cold (think fall/spring). The material feels a bit like a light fleece jacket but that is why it is so cozy. The pockets are nice and deep. I purchased my usual Castelli size, which is a Large (though I wear a small or medium in regular tops/dresses), and that worked well because in my experience all of their clothes run a bit small. This was a good purchase.

Cozy Jersey

  • Fit: Runs large
  • Size Bought: Large

This does run a bit larger than Castelli does usually. I am keeping the size L since I can wear a thick base layer underneath. I am about a size 6/8 on top depending, but with wider shoulders. Soft, fleece interior will be great for fall rides and layered for winter depending upon your location.

Gave as gift

  • Familiarity: I gave it as a gift but have feedback to share

I gave this as a gift to my sister and she said she likes the weight and fit. She has used it several times and says it wears comfortably and is a great layering piece in the winter and will be a good lightweight jacket on its own in spring.

Lush Plush Soft and Comfy Warm Jersey

  • Familiarity: I've used it once or twice and have initial impressions

If you are looking for a warm jersey, this is it. Very soft, plush, lush and comfy thick fleece jersey. Once you put this on, you may never want to take it off. While it is thick fleece, the top weighs very little. It is not windproof, but I have other windproof jerseys and jackets and just wanted a jersey for cool and cold weather. I usually wear a medium in Castelli form fit tops but in this one, I had to downsize to the small. It was still long enough on me though. I am 5', 100 lbs. This top is so nice, I have several of them.

Thank you Marisa! This review is so helpful! It's getting cold in SLC so I think I need to pick one of these up.
