Control the road.

Castelli designed its new S. Tre. 1 Gloves for the rider who prefers a minimal design, but still demands the cushioning, support, and solid grip necessary for day-long endeavors in the saddle.

Castelli constructed the S. Tre. 1's palms from a synthetic leather with a thin foam insert padding. This combination breathes extremely well and provides just the right amount of cushioning for choppy roads. The result is a palm material that allows you to adequately feel the road through the bars, while keeping your hands cool and dry. Silicone printed logos across the palm inserts provide texture for added grip, and microsuede panels along the backs of the thumbs allow you to comfortably remove sweat from your face.

The back panels utilize lightweight printed Lycra, which stretches to conform to your hands and aids in the transferring of moisture from your skin. Hook-and-loop closures at the wrists keep the gloves securely fastened, and easy-off central pull tabs let you remove them with ease.

The Castelli S. Tre. 1 Gloves are available in six sizes from X-Small to XX-Large and in the colors Black/white, Black/yellow fluo, Red/white, White, and White/ocean.

  • Familiarity: I've put it through the wringer

Great fit, lightweight with minimal padding. I was worried that the padding would not be enough but after several rides I actually prefer it to gloves with denser padding. Buying second pair as they are a great deal right now.

Love 'em

  • Familiarity: I've put it through the wringer

Lightweight, fits like a second skin, nice velcro closure and just enough padding in all the right places. Much better than the S. Rosso Corsa Gloves I was wearing and by far my favorite gloves yet.

Castelli S Tre 1 gloves

    Excellent feeling glove very lite not a lot of padding which make the glove feel lie second skin great fit

    Best Glove I have

    • Familiarity: I've put it through the wringer
    • Fit: True to size

    I like how thin these are, very light weight too. Gives up some padding for that, but oh well, it's not noticed. The top material is very form fitting and flexible, I really like that about this glove.

    the get the job done Glove

    • Familiarity: I've put it through the wringer

    I can now say that i have put these through the ringer! they are very good gloves. i still like to see how long they last most gloves last me a season depending on the mileage. like the ease of pulling them off. like the fit - did not size up, like the material for warm weather and had good grip. very happy.

    I'm wondering about sizing here... I typically wear XL or XXL in winter gloves, but according to this sizing (my middle finger to base of palm is 9") I"m barely a LRG. Is this correct? (This IS my first pair of biking gloves, so maybe I'm just a noob.) Thanks!

    Best Answer

    Well, the LRG fits me despite my wide hands. Trust the sizing guide. One note on these though, the padding in the palms is light, and I think I need something beefier.

    I was initially shocked at how tight these gloves seemed to fit, and wondered if I was sent the wrong size (I ordered Large). They feel small when putting them on and taking them off -BUT - once they are on the fit is, at least for me, absolutely perfect. The padding is not excessive, but is a great balance between grip/feel and protection. These gloves 'disappear' on long rides. These are my go-to gloves, a great all-rounder that I'd highly recommend.
