Give your Lycra a break.

While today's jerseys fit and feel much better than what was available even just a few years ago, we still don't really want to have them on while we're milling around before a race. Castelli knows this too, which is why it made the new Race Day T-Shirt for all your pre- and post-bike activities.

Made from a 60/40 cotton and polyester blend, the Race Day T-Shirt features a "slim" fit, contrasting neck tape, and screen-printed logos front and rear. And while the fit is described as slim, Castelli is quick to note that this is by no means an ultra-tight "euro" cut. For reference, someone who is six feet tall and weighs 175lbs will fit a Large shirt very well.

The Castelli Race Day T-Shirt is available in sizes Small to XXX-Large and in the colors Black and White.

  • Cotton and polyester blend
  • Slim-fit crew

How to Measure:
For best results, take measurements over your underwear.
Measure under your arms, around the fullest part of your chest.
Measure around your natural waistline, keeping the tape a bit loose.
Measure around the fullest part of your body at the top of your legs.
Using pants that fit well, measure the crotch seam to the bottom of the leg.

Here's what others have to say...

Good shirt!

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

I actually got this because I wanted a basic white T with a slim fit to wear under a dress shirt. I've worn it as an undershirt and normal shirt and it's great. As others have mentioned, slim fit, but to be expected from Castelli.

Great shirt

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

Nice shirt - fitted (tapers at the waist), nice quality materials (thick with a little stretch) and looks great. Medium fit me well (I usually wear Large for Castelli biking clothes - about 5'10" 150 lbs).

Solid T

  • Familiarity: I've used it several times

High quality materials and top-notch manufacturing, per usual for Castelli. Solid casual T! <br ></article><br />Be careful on the sizing. If you're in between sizes, size up as it's definitely a slim fit.

Pretty good

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

Although the specs say its regular fit, it's definitely Slim Fit. It's kinda stretchy and makes a good running shirt. I usually wear Large T-shirts but I should have went with XL.

Get your regular size if you want a slimmer fit shirt, and go 1 Size up if you want a more casual type shirt.

Nice T-shirt

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

Nice T-shirt. Purchased on a bit of a sale and very happy with the fit and comfort of the shirt.
