Product Data

Road: Yes

Performance Perfected

After 12 years of evolution and millions of miles of on the road testing, where exactly have the Castelli design team squeezed out even greater comfort and performance? Well, the heart of any great shorts is the seat pad and for this year the Progetto X2 Air is softer and more flexible than ever with a seamless top layer giving you a pad that is virtually unnoticeable.

Progetto X2 Air Seamless Seat Pad

Progetto Air Seamless

Why is the Progetto X2 Air Seamless seat pad so incredibly comfortable? It begins with the first contact point against the skin, the upper skin-care material. It's now seamless and even softer than previous versions for fabulous comfort. The next layer, Castelli’s infinitely variable thickness padding, imparts just the right level of support where you need it, thicker under the sit bones and thinner on the sides and under the perineum. The results are intense comfort with reduced bulk. 

Lastly, to really push home superior comfort levels, perforated viscous padding is added under the highly sensitive ischial and perineum pressure areas, offering luxurious support when you're on the saddle for hours on end. 

GIRO4 leg grippers

Next, GIRO4 leg grippers get enhanced stretch and yet are grippier than previous versions so the pressure is spread wider but without any loss of traction on the thighs. A lie-flat raw edge provides a smooth transition between skin and shorts and the vertical silicone grippers hold firm without exerting excess pressure. 

Improved Bib Straps

Lastly, the Stripe Mesh straps are reduced in weight and yet offer enhanced support, in all honesty, you'll barely notice they're there, but that's the whole point. Castelli have also used a more breathable material meaning even greater comfort when the pace picks up, wicking away sweat before it can pool and cause discomfort. Team Sky wanted a radio pocket too, now it's lie-flat and unobtrusive, a real pro-ready design.

The improvements may be subtle, but they all add up to a major step up in comfort, providing support on both the longest and shortest rides.

Pro Performance

The Free Aero Race 4 are the go-to race shorts for Castelli's pros, and with many riders clocking up 30,000kms a year on the saddle they're very exacting with regards to their kit. Castelli listens, learns, tweak and improve products and the results speak for themselves as soon as you pull the Free Aero Shorts on. The pros love them, and we think you will too.

Rated 1 out of 5 by GPCC from Whats happened to Castelli quality? Have bought mainly Castelli clothing for best part of 10 years and Free Aero Race bib shorts have always been a favourite of mine. However, this latest version whilst comfortable have literally fallen to pieces in 10 or so rides. Stitching has come apart, worn threadbare in some places. You expect more for the amount they cost. I won't ever buy Castelli clothing again and have switched to ALE which is as comfortable and appears to be much better quality.

Rated 5 out of 5 by TheShadow66 from Perfect fit bib shorts and really classy My first pair of higher end Castelli bib shorts. I do have other expensive pairs and can say that these are up there with all the other names(you know the ones). The cut on these are slick but not restrictive and the pad is super comfy. Can’t wait for next summer so I can really appreciate them again

Rated 5 out of 5 by NorthernCyclist from Super Comfy Elite level bib short I've tried and tested many bib shorts over the years and these are fantastic. 79cm waist, 52cm thighs, 62kg and 173cm tall MEDIUM fits perfectly. all day comfory, very light and slightly compressive but in a way that once riding you think you've forgotten to put them on.! Easily ride 240Km in these with no issues. Chamois is top quality.
