Cool shorts for long climbs.

You'll likely appreciate the aerodynamic properties of Santini's fit-like-a-glove BCOOL Bib Shorts while spinning on the flats or powering through rollers, but it's the long, slow, hot grind up your local HC climb that will really show you the plus side of these shorts. Everything from the compressive fabric to the barely-there chamois contribute to a comfortable ride on a hot day. Now if only those eight miles at nine percent of Little Cottonwood Canyon — our local HC climb — would be as forgiving.

The shorts are made from a synthetic blend Santini is calling Lycra Newport. In this case, Lycra translates to stretchy and accommodating and Newport translates to a gentle compression that helps reduce the muscle fatigue caused by miles and miles of jostling oscillation caused by road noise and general saddle-bound movement. The side panels incorporate carbon particles in order to improve thermo-regulation and protect against UV rays. Carbon also eliminates odors, so you may want to pick these up as a gift for your riding buddy who doesn't wash his kit between rides. The shorts are finished with anti-slip Lycra leg bands that don't pinch or restrict movement, and the elastic bibs serve as a frame for breathable panels of mesh.

Of all the construction elements of the BCOOL Bib Shorts, Santini may actually be proudest of the GITevo chamois — and for good reason. The Italian manufacturer boasts that the GITevo is the lightest gel chamois in its line. While we haven't torn it out of the shorts to weigh it, the mesh and gel construction certainly feels both light and non-restrictive while still offering the protection we expect from a premium chamois. The usual perineal channel and sit-bone support make an appearance, and the microfiber cover is soft, stretchy, and antimicrobial.

A good bib for mild hot weather

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

The bib is comfortable, stays in place, is fresh enough, and has worked well so far

Avg. ride time: 6h 46m per week

Nip chaffer if there ever was one ...

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs small

First, these bibs run small in the torso area ... I am 5’9” at 168lbs and the straps pulled in to my shoulders while riding. This could be the reason why the straps chaffed my nipples almost raw just 20 miles in to ride (had to unzip my jersey to wrap around strap to finish the ride back).

Chamois was a bit flat and compressed during ride much so that I was surprised that I was squirming in the saddle just an hour in to the ride.

That said, the fabric felt cooler, more porous than normal cycling gear and, despite what another reviewer said, it does cover your junk adequately!

Great fit, good value

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: XXL

I got these Santini BCOOL bibs for summer use, and it is only February now. I am 6ft 3 and 230, and the size XXL fit is perfect. Since it is February, I wore them as a base layer for some 20 mile rides and the fit is great. The Chamois feels good on these short and cool rides. The real test will be when the weather warms up. I like the lower cut in the front and sides. I expect these bibs will have good coverage, and great cooling once the weather warms up.

Love Em

    After using several Santini bibs last year, it has become my preferred bib choice, prior to Santini, I used Giordana FR, Mavic, Sugoi and Gore bibs.

    I live in SW Colorado, and my riding is is primarily mountain biking and some mixed road riding, typically longer rides that last several hours at least.

    I find these shorts work much better than any others I have used on hot 100deg days in desert riding, like Moab. The cut and fabric is perfect to keep sweat from being an issue down below, where they allow better air circulation at the bottom of my tummy and crotch area = more comfortable ride. The cut gives you less coverage on the front sections, but for me, it is reasonable to keep your privates covered.

    I am a small person, 5-4 with athletic build, the size small fits me perfect. Santini has been consistent in their sizing, small is perfect on the 5 pairs I own. Most other brands, the inseam is too long for my stubby legs. Santini also publishes a very detailed and good size chart on their website.

    The Saniti sizing also follows suit in the padding. I have not had any issues with chafing and the padding tends to be in the right spots to keep me comfortable and just as important, not bulky and in the way.

    Despite other reviews, these bibs are similar in quality, pad and feel to the other Santini bibs I have.

    Not as advertised!

      These bibs are cut and labelled as BCool bibs but are made from Thunderbike lycra and contain the GITevo chamois (not the MIG chamois). They are clearly an inferior product compared to that advertised. This issue raised with Backcountry who knowingly continue to sell them mislabelled and with misleading advertising.

      It has been confirmed from Santini - the delivered product from Backcountry is definitely NOT the genuine classic Santini BCool bibs.

      Good fit

      • Familiarity: I've used it once or twice and have initial impressions
      • Fit: True to size
      • Size Bought: xl

      Did a few rides in these and really liked the fit. The only thing I didnt like was the chamois. It is very thin and seemingly hard. It does not fit me and where my sit bones meet the seat. They are great bibs but I get uncomfortable about 1.5 hours into a ride. I am 6'4" 180lbs and ordered the XL. It fit fine for my build. Again I just dont like the chamois

      Tried these last fall and again this year. Fit feels good but the straps fold over and become more like cords. Nip chafers. Many jerseys won't cover the low front of these. And if you like giggling tweens whilst stopping for a drink, the small viewing window right at the crotch works wonders!
      I have already moved these to the back of the closet.
