C5 Optiline Bib Short+

Realizing that even the warmest days in the saddle can often encounter whipping winds, Gore Wear designed their Men's C5 Optiline Bib Shorts+ with the newest Gore Windstopper Cup technology. This technology is comprised of an ergonomic, upturned panel of windproof fabric that blocks oncoming winds and relieves pressure along your most sensitive bits. It's combined with Gore's Advanced Road chamois for plush, moisture-wicking support that satisfies even the most discerning of cyclists with multiple densities of foam cushioning.

Delving into the construction of this premium bib short, you'll find it's made of lightweight, breathable materials optimized for riding in warm conditions. Full mesh bibs provide upright stability while breathing extraordinarily well when the mercury skyrockets in summertime. Optimized seam placement reduces the scratchiness inherent to cheaper bib shorts where stitching digs into sensitive skin, only to lead to chafing and irritation after hours of non-stop riding. Additionally, you'll find a lie-flat hem that remains firmly in place, but without uncomfortable bunching or pressure points.

The MOST comfortable Bibs

I've put it through the wringer
Size Bought:
5' 9"

These are by far the most comfortable bibs I have ever worn. Great for spin class or century rides. I could go on and on and on....

Good bib but different

I've used it several times

It feels like I'm not wearing anything when I have these on which is very different than the rest of my bibs. They are great indoors and outdoors; however, if you prefer the nice compression fit that other bibs provide, steer clear.

Don't recommend

I returned this product before using it

They fit like a garment bag and the material is sketchy. Returned.

These are subpar

I've put it through the wringer

I own 2 pairs of C5 bib shorts+, and a pair of c7 bib shorts+. I've owned them for about 2-3 years. I love them. They are quality, and you immediately feel the high quality when you put them on. They still look relatively new, and feel just as great. I recently bought a pair of c5 optiline (red band/accents at bottom of shorts). It's as if a different company made these shorts. You immediately feel the low quality when you put them on. The fabric is too stretchy, and the red band/accent on legs immediately lost their shape and look like an old cotton shirt that has completely lost its shape after less than 2-3 months of wearing them. The chamois is thin, and not comfortable at all. Because the whole bib short is too stretchy, it doesn't stay in place when you're riding, and it feels like you're swimming inside the shorts. Don't buy the optiline.

Nice bib, chamois needs upgrading

I've used it several times

The fit and material is very nice for this price point. However, for cyclists who do a fair amount of mileage, this chamois simply will not cut it. If they upgrade the chamois to match Pearl Izumi or Castelli's top-of-the-line chamois, I'm in. Serious cyclists will require a better chamois, but great bib for recreational cyclists.

Initial impressions are Great

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

I'm 6'2" / 185 lbs / 34" inseam / 40" chest and the XL fits like it was poured on. For the short ride I used them for they were great. I'll update this once I get 40-50 miles but am expecting to be very happy from initial impressions.

American Fit

I've used it several times
Size Bought:
5' 8"

I ordered this bib in M and L. The large chamois sat like a diaper and was obviously too big. Medium fit like a glove. It sits where it needs to be and doesn't move when you walk. The bib starts just above the knee and isn't overly tight yet doesn't have any movement when riding. The shoulder straps are wide, soft and don't have an uncomfortable pull. There is no "cup" cut out that may seem that exists in the photos. Thats just the way stitching comes together and is an optical illusion in the photo. They did place a piece of fabric between the outer bib and the chamois over the groin area to block the wind and it work really well. However, don't expect a special cup cut out for your junk. Unfortunately everything gets compressed like in all the other bibs. Overall, the material sits tight and doesn't move. I'm average build and unlike Castelli bibs, where I need to order 2 sizes up, this one truly fits for an average US male. I was comfortable in this chamois on multiple 30 mile rides and had no issues.

Excellent Bibs - Highly Recommend

I've used it once or twice and have initial impressions
Size Bought:
5' 8"

What a great pair of bib shorts. I'm 5' 8" and the length of the legs was perfect: Just above the knee when standing. Light compression and very comfortable. I wanted something with some "styling" and the white accents on the legs fit my interests. Great shammy. Highly recommend you consider these bib shorts.
