Ordered these and the prime, but didnt like the horizontal wais+x suspenders design of the prime. The fabric on these arent as lux, and the leg grips are a little tight but actually found the fit perfect (XL) and expect the grippers to stretch a little over time. The Cham is more "back half only" than other designs. Wish it was a little denser but been great for 2 hours rides. Better than other options at ~$100

The elastic bands around the thighs are so tight that it completely ruins the product for me. The bibs are nice and everything else feels good. I have the correct size.

6'1" 200lbs Now that the RBX line is gone, I decided to give these a shot. Overall the jersey and bibs are very similar to RBX. I ordered the same sizes that I bought in RBX and it fits great. The bib material feels less 'plastic-y,' but about the same thickness. The mesh backing is nice, but the straps are now much thicker, rather than being mesh like on RBX. The pant length is a bit longer and the cuffs grip tighter. The dark navy bibs may as well be black. The jersey is also very similar material to RBX jerseys. The chest fits a bit tighter, which is nice because the RBX always bunched up a bit on my chest when on the bike. The overall shirt length seems a bit longer, as do the sleeves, the waist cuff also grips quite a bit tighter and have a thicker band. Pockets on the stomach are a nice touch, a bit unnecessary. If you liked the RBX line and want something similar, this is a fine choice. 4 stars due to price creep, RBX pricing was awesome. Increase review char limit!

Great fitting bibs with the an chamois. However the lower leg band flaps in the wind. The fit is correct (XL) but band is poorly made, cheap and not typical Specialized quality.

Agree with other reviewer on here. Enjoyed the Prime bibs in L, but the Foundation bibs in L had a much shorter inseam and uncomfortably tight leg grippers (despite the size chart saying I should wear an M). In black, I didn't notice the fabric being too revealing, but I can see other colors being problematic. Returning before riding in them.

Happy to try before I buy. The Fit was inconsistent with the Prime and SL bibs. These feel like a step backwards from the RBX Bibs they replace. The leg band elasticity did not match the compression of the thigh, making for an odd crease in the leg's silhouette. Sizing up to a large from medium did not solve the issue. I tried on Dark Navy and could clearly see body hair through the garment. This combined with a small frontal coverage from the chamois left the bibs feeling very revealing.
