Castelli Endurance 3 Bib Shorts Description:

The Endurance 3 Cycling Bibs uses Castelli's renowned top-of-the-line Progetto X2 Air Seamless seat pad in a traditional bib short where every little detail has been obsessed over to ensure maximum comfort on your next long endurance ride. A great pad is useless without a thoughtful fit, so Castelli utilized their Endurance Evolution fabric and cut the panels to provide good compression while maximizing moisture management. And it's all held in place with the amazingly comfortable GIRO3 leg gripper. These bib shorts offers exceptional value and are ready to deliver lasting comfort on your longest rides.

  • Mesh bib straps and back to keep you cooler
  • Progetto X2 Air Seamless seat pad for even greater comfort and improved airflow

Castelli Endurance 3 Bib Shorts (Black) (S)
I echo the reviews with fit issues.I can often get into a medium, but with this bib, I must go to XXL. Be advised. Aside from that, these are classic Castelli: beautifully constructed and comfortable. I'm eager to put them to use.

Castelli Endurance 3 Bib Shorts (Black) (L)
I’m 5’7” 170lib make and have requested a refund on this item because it’s description is inaccurate. I’ve always been a medium and following the instructions, went to a large. Super tight and need a XL. You’ll need to go up 2 sizes. Good price bad description.

Castelli Endurance 3 Bib Shorts (Black) (2XL)
These are comfortable shorts. The pad is very well designed and I look forward to many long rides with them between me and the saddle. That said, the reviews about Castelli sizing are completely correct in that I coulda/shoulda/woulda ordered two sizes larger than my normal size to get it 'right.' I typically wear an XL (6'5', 195 lbs) as I'm "tall and lanky." This 2XL is pretty good, but still quite snug and I'd like a little more length in the shoulder straps. Nashbar doesn't sell a 3XL in this short so I'll be fine, but could be better. I wouldn't hesitate to recommend the shorts, just be aware of the sizing issue.

Castelli Sizing: Many Castelli products are designed with a European race-fit. It is not uncommon to size up one or two sizes for the right fit.

Note: All measurements are provided by the manufacturer and may vary depending on how measurements are acquired. Castelli instructs that for best results measurements be taken over underwear. Castelli recommends sizing up if measurements fall between sizes for a better fit.
