    Given the discipline's solitary nature, the jet-engine triathlete's only real enemies on the bike leg are bonking and wind drag. Castelli designed the men's T1:Stealth Jersey to address them both, particularly the latter. By combining Velocity front panels and Velocity Mesh shoulder and back panels, Castelli imbues the T1:Stealth with hydrophobic, quick-drying properties and a stealthy, flat-lying fit that eliminates wind-catching, transitional ridges from panel to panel and jersey to skin. The result is a claimed three minute gain on Castelli's two-time Kona champion Free Tri Suit over century distances.

    To ward off bonking, Castelli includes two pockets on the lower back. The pockets provide enough space for gels, energy gummies, and power waffles, and the side-oriented openings effectively reduce their aerodynamic profile in order to preserve the gains made by the jersey's fit. The elastic, silicone gripping waist helps keep that fit in place, and the addition of UPF 16 sun protection helps your sunscreen keep up during hours-long events.

    • Velocity and Velocity Mesh lie flat for aerodynamic gains
    • Prosecco treatment diffuses moisture across the jersey's surface for fast drying
    • Full-length zipper to ensure optimal fit
    • Side-entry pockets store energy food without an aerodynamic penalty
    • Item #CST006D

    The fit is odd.

    • Fit: Runs small
    • Size Bought: small

    Purchased this for a smallish male friend. Loved the fabric and the look; however, the fit is just not right. The fit along the shoulders is tight and the hem rides up over the hip. But it is a cool looking top.

    My Favorite Jersey

    • Familiarity: I've put it through the wringer
    • Fit: Runs small
    • Size Bought: Medium

    Not only is the quality top-notch and not only is this a perfect fit, but they've done something here that I don't think anyone else has done. They've made the pockets side-entry on the back. All my other jerseys have pockets that you've got to reach into from the top. I know that this is the way 99.9% of all jerseys are designed but having side entry pockets is really nice. The pockets are deep enough that everything stays in there, so that's not an issue but just reaching back and straight into the side of the pockets on either side while riding is a nice convenience that I really wish I had with all my other jerseys. I'm typically a small in everything and because Castelli tend to run small I got a medium. It does fit like a small in most other brands. I'm not sure if I could have fit into a small but I may order one and see. It would definitely be the most snug fitting jersey if I did. The medium fits like a race fit small in another brand anyhow so I'm very happy with it. This jersey is my new go to jersey for most rides now.

    Where do they get the sizing from!!

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

    I ordered an XL after reading reviews about Castelli's clothing tending to be on the small size. My chest is 39cm, so according to the sizing chart I should be a Large, so I went for the XL. When it arrived I was shocked at how small it appeared, It looked like a child sized jersey compared to all my other ones! I carefully put it on, and it was a tight fit especially under the arms and I'm not particularly muscular in that area! It was tight everywhere else and I'm a slim build, , but the tight fit under the arms persuaded me that it wasn't for me. Also, the rear pockets were something of a surprise, (even though it does mention side entry pockets in the product description) they are not easily accessible like traditional pockets, maybe to do with it's aero profiling, so again another reason for returning this product.

    The tight fit under the arms because Castelli will usually rotate the sleeves to make the jersey fit right in the riding position and eliminate bunching. This is by design since you don't ride with your arms straight down like you do when standing.
