Supportive, flattering, lightweight.

When the summer heats up, any extra material on your arms compounds the discomfort as you get toward the top of the climb. Castelli know this, and designed the Regina Sleeveless Jersey to be as full-featured as a typical cycling jersey, but ideal for those scorching summer days. And, Castelli even built in a bra top so you get to wear one less layer.

Found it true to size

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

Great for hot days, especially built in bra. Pockets are nice and large, enough room to pack for long rides. I got a size S but an XS would've fit better. Kept the S because a bit of looseness is welcome on hot humid days. If there will be more colors (I got black) I'd order again. More jerseys need built in bras!

Run so small, so size up 1-2 sizes

  • Familiarity: I've used it several times
  • Fit: Runs small
  • Size Bought: Large

I'm usually a medium, but based on the reviews, bought a large (the XL would have been good too). Even the large is on the tight side, but I don't mind as much. Has a built in shelf bra with a front half zipper and 3 large back pockets (plus a small key pocket). I have the royal blue with pink and white accents. A nice tank jersey for the summer, but definitely size up 1-2 sizes.

The Large looks like a small

  • Fit: Runs small

Runs small, very small

Very Small

I sized up as recommended but should've upped 2 sizes as one other reviewer noted.

Sizing is off

  • Fit: Runs small
  • Size Bought: XS

I'm 5'2", 106 lbs and could barely pull the XS over my head. I was afraid I might rip the fabric. It's a striking jersey but I will return it for a size M and I usually always wear XS, small or 00 in everything.

Love it but returned as is very small

  • Size Bought: S

This jersey doesn't 'run small'. It is tiny! I'm have a 35" chest and 25" waist. I'm a XS or S in everything I purchase. I ordered the S and it appears to be sized for a child. It might have fit me when I was 11 years old. Quality is great, love the style, color is terrific and will look great with the coordinating Castelli shorts I purchased. Returned for a medium, which was too small. Returned the medium for a large and it's still too small. I give up. : (

Not as pictured

I ordered this in Surf Blue which looks so pretty online. In person, the colors, especially the pink, are a bit brighter than pictured. This is not too bad as I do like my cycling gear to be visible to cars, but it was just not as pretty. Also, in the picture, the part of the built-in bra that's visible above the zipper is black. The item I received is white and this changes, cheapens, the overall look of the garment. The material feels nice and would probably be great on a hot day. I am usually between a size XS and S depending on the fit. After reading reviews, I ordered a size M and it fits perfect. A smaller size would be too small for sure! I'm disappointed with the color, am leaning towards returning which is sad because I was really excited about it.

Thanks for the review, Jennifer. Very informative.

Runs very small

This jersey runs so small that it looked like a child's size. I would order up 2 sizes if you decide to purchase it.

I am a size 6, 27 inch waist, and a 32ddd/34dd and i wear a large or extra large in most of their tops. If you can get a size that fits they last!
