Fondo Full-Zip Long-Sleeve Jersey

Skip the frills and fuss and opt for warmth and style with the Castelli Fondo Full-Zip Long-Sleeve Jersey when the temps start to dip. Packing in heat, the Fondo Full-Zip wraps you up with the high-loft fleece of Castelli's Warmer fabric to trap in warmth while actively wicking away sweat. It fits close to the skin to optimize moisture transfer when you're pushing through your sprints, and fit comfortably under a vest if the temperatures really start to plummet.

With Castelli's designers skipping obnoxious add ons, they were able to focus on ensuring a clean and clutter free cut with just the features that matter the most. Hightlights are the spacious back pockets for securing tools, gadgets, and snacks on the ride, and an extended tail that offers coverage when you're down in the drops. In front the jersey is equipped with a full-length easy-sliding YKK zipper that can be opened for quick heat dropping during big climbs, or tucked nearly into the Zen neck flap at the collar to prevent rubbing when you tuck your chin down through a sharp breeze.

  • A simple and elegant fleece jersey for frosty rides
  • Warmer fabric offers high-loft fleece for warmth
  • Polyester construction is ideal for moisture transfer
  • A slim cut makes for easy layering on top
  • Stay covered in the drops with drop-tail hem
  • Pack in the snacks and gear with three spacious pockets
  • Reflective accents help you stay visible in low light

Great quality jersey

  • Fit: True to size
  • Size Bought: xl

Fits looser than most other Castelli jerseys, I mostly take XXL in Castelli but XL fits perfect with this jersey. Deep pockets, light weight for Fall or Spring weather. I find it's good in mid 50's temp and with a base layer in the higher 40's to lower 50's

Sizing Off

    I always wear XL in Castelli. I’m 5’10” 175 pounds. This fit like a sale. Loose at chest and a balloon area mid area. Had to return it. Seemed like nice jersey otherwise.

    Bravo Castelli

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

    Stylish and well made. Surprisingly true to size, not the normal Euro too small sizing. Extremely warm, blocks the wind well. My new favorite jersey.

    Runs big

      I’m normally an XL in Castelli up top. I’m 5’10 175 lbs and fit is good in the chest area but lots of dead space on the stomach area - too much. Nice jersey otherwise.

      Absolutely, almost, perfect...

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

      I purchased this jersey for fall weather. It was perfect with a heat gear base layer, an absorption layer and the Fondo jersey on top. On a 50+ mile ride, with constant wind and temps in the 50's I was comfortable and just the right amount of warm. This jersey looks great (Castelli leads the pack in design), feels great and functions flawlessly. If you're worried about sizing, take your measurements and match them to the sizing tables. Your Castelli jersey will fit perfectly. Don't assume.

      Great Jersey

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

      Warm and comfortable. I'm built more like a football player than a cyclist but the XXL fit great. Arms slightly tight but better tight than baggy where it flops around in the wind. Rode when it was in the 40's and once in the low 50's. Worked well in both conditions. I just used different types of base layers for the different temperatures.

      Great cold weather jersey , too big

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

      Castelli sizing is all over the place. I would have given this 5 stars but the sizing is off... I am returning for a size smaller. I order two sizes bigger in Castelli but this item is much closer to a Large than not.
