Very Pleased So Far

Haven't tried Castelli bibs for a long time as when they first were offered by BTD I had quality control issues . The pad on 2 bibs came completely unstitched after one ride . As usual BTD gave me great service with my issue. Since then I've use mostly Louis Garneau bibs and they have been excellent.

Cycling buddies have been using Castelli products with great success so when I saw the Competizione bibs they looked good so I ordered a pair. I'm 5'10" and weigh around 176. I ordered a L but had to return them for the XL that fit perfectly. So when ordering you should in most cases order one size larger.

When the weather is not hot my rides are in the 5 to 6 hour range. After two 70 plus mile rides I'm really pleased with the fit and comfort. The Kiss Air2 pad seems to be excellent as are the leg grippers and material .

Great shorts, problematic sizing

Ordered these nice shorts in large, same nominal size as my previous Castellis.

Pair I received was labeled Large, but they were tiny

on me.

(I�m 150 lbs, 5�11�, 34 waist) and they also had that annoying (to me) low cut waist now popular.

Had to return (which, btw was zero problem).

I�ve had sizing problem b4 w/ other Castelli products.

I�ll go two sizes larger, see if that works, as I really like these shorts

Overall a good value

Purchased these during one of the Gold Express Deals put on, and am very happy with the overall value. Super warm for conditions from 30-45 degrees (Fahrenheit). My only restraint on giving it a full 5 stars is restricted breathability, which is why I think the mid-40s in temp is the warmest I'd rock these guys. A workout is to unzip once warmed up on the bike, but the fingers still get damp. I'm not sure anyone has produced gloves that can strike a balance of windproofing, warmth, and breathability but for the price, these come darn close.

2nd Pair of these

First pair ordered last year have held up incredibly for multiple hour rides. The pockets are bar-none the best, keeping your do-dads close and secure. The graphic on the back is starting to peel but the chamois longevity is all I care about and 10+ hours later it's still plump, not Castelli's best but it's sufficient. This second pair I recently ordered had a label that was caught in the stitching but I cut those out anyway. It also had a slight defect in the right leg where the seam didn't carry all the way down the leg so the panels have a slight split at the opening. Stitching is secure so I don't see it being a problem - just seems quality control is dropping and I may have to find another go-to bib. 6'3" 180lb 33" waist the medium is solid
