Go the distance.

The Assos FI.Mille A.360 bib short was a mainstay of the Assos apparel line for nearly a decade. It was always known as their "Long Distance Short", and in the revamped version here known as the FI Mille S5, this essence remains the same.

Why "Long Distance"? It's for two key reasons: First off, the FI.Mille S5 provides more stretch and less compression than the FI.13 S5. This is due to both the fabric selection, the cutting lines of the fabric, and the number of total panels of fabric. While the added stretch and malleability of the fabric provides less muscle compression than the S5, it moves with a silken closeness to your body as you pedal. If you've ever ridden for 6 hours at a clip, you know little things matter a whole lot, and this is one of those comfort details you'll appreciate.

The other "Long Distance" characteristic of the FI.Mille S5 is its unique chamois. Like the FI.13 S5, the chamois is curved to perfectly fit your body, and it has a cut at the front of the chamois to reduce genital pressure. In addition it has the same softness and heat-ventilation dimples of the FI.13 chamois. What gives the FI.Mille S5 chamois its "Long Distance" designation is the fact that it's a bit bigger in surface area than the FI.13; it stretches less than the FI.13; and it has a stabilizer built into the chamois, causing it to move less during your pedal stroke.

The FI.Mille S5 makes strategic use of A430 fabric to wick sweat and elastic fabric to reduce genital pressure. And it's built with the same AEPD cut as the FI.13 S5 to feel like it "clicks" in place on your body when you're reaching for the bars. The added stretch of the FI.Mille gives it a perceptible level of comfort. Bigger riders -- and non super-skinny riders -- will appreciate how the FI.Mille S5 fabric stretches laterally on your body with greater ease than the FI.13 S5. If the FI.13 S5 feels right length-wise, but too tight width-wise, you'll experience something totally different with the FI.Mille S5.

The FI.Mille S5 is available 5 colors, in sizes Small-TIR. It comes with a small jar of Assos' legendary Chamois Cream as well as a small bottle of Active Wear Cleanser, plus a wash bag. Please Note: Assos now makes these bib shorts in a long and regular leg length. This is the traditional long version.

Need Large Thighs

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

Well made, nice material, very good chamois but you need large thighs. The legs are a little large and the leg grips are not tight enough so the leg material tends to ride up toward your crotch. Guess my thighs are not large enough. I got the medium which fit great except for the legs. I'm 5'8" and 155#. Based on this I would not have ordered again.

Jesus' Bibs

  • Familiarity: I've put it through the wringer

These are the best bibs for riding. The chamois is pure bliss. I would recommend it in a heartbeat. The legs are not as compressive as others that I have they are compressive enough to not be a problem on any level. The straps I great and the material is solid.

Best long-haul shorts money can buy

  • Familiarity: I've put it through the wringer

These are expensive enough that I set them aside for especially long rides, and they are especially rewarding for that purpose. Although Assos says that these will not last especially long, I have never found any Assos product to be flimsy and still have Assos shorts that I got in 2007: you'll want to follow their directions for putting them on, washing, etc., for best results and real longevity. Watch it though--they wear out in the seat first, and I have seen Assos shorts out on the road with big patches of bare ass. Check the mirror every now and then!

The turquoise pad is controverisal, and I think it is marginally better than the old orange pad. It seems softer, but doesn't seem to be going "flat" or wearing any faster. If you prefer the orange pad, it is made by Cytech and can be found on Rapha and Search and State shorts, both are excellent alternatives. I prefer the Assos Mille shorts to both of those.

The shoulder straps are the best in the business, about 2.5" wide and very comfortable. The legs fit well, and while there have been complaints about the band fitting "loose," it tightens up well when you are actually on the bike.

The only thing I don't like about them is that there is a panel on the front made out of different material that points right at your junk and suggests a triangle of pubic hair. When your friends make fun of you (and believe me, they will), respond in a German accent that Americans are prude in these matters.

Comfortable Bibs

  • Familiarity: I've put it through the wringer

These are great shorts for those long rides; very comfortable and fits really well. I currently own 3 pair; 1st pair Jun 2011; 2nd pair Feb 2012 and 3rd pair Mar 2013. The only problem that I have had with all these are the elastic at the bottom of the thigh. They lost their elasticity from use. The last pair I purchased in 2013 only took a few rides to loose the elasticity. It is usually confined to one thigh but one pair it was both. I still wear the shorts and was thinking about sewing the elastic.

Becoming addicted to these...

  • Familiarity: I've put it through the wringer

I've bought a pair of these, and after using them for a week, ordered two more...
These are almost perfect bib shorts and will improve your comfort on the bike by 100%
Especially during winter with long session indoors, these make the difference between being able to get to the end of the session and climbing down in pain.
Must buy !!!

Won't wear anything else

  • Familiarity: I've put it through the wringer

I currently own two pairs (3 if you count the FI.Mille_S5 knicker-version) - and won't wear anything else. After years of use/thousands of miles they are still going strong. Fit is so perfect and the chamois so comfortable you might actually look forward to wearing them. Seriously, words cannot describe how much better the chamois is than any other bike short. If you ride with a club/team, be prepared to ditch your team kit shorts (Note: when you do ditch the kit shorts, it is helpful to be prepared with excuses on why you are not wearing them)

Best Bib Shorts Ever

  • Familiarity: I've put it through the wringer

I have tried every other brand and style of high end bib short and these are the best by a long shot. I have 4 pairs and have owned them for 3-4 years each and have put a couple thousand miles on each with only minor wear visable. The chamios is huge and covers any areas that might be prone to friction burns with other brands. The fabric really compresses nicely and hasn't lost any compression over time. This is also the only bib short I've ever owned that hasn't had an issue with stitching after a lot of wear and washing. I really hope that the new S7 models are made with the same quality. The only real drawback is the price; I think they are more expensive than my first bike.

An outstanding pair of bibs

  • Familiarity: I've put it through the wringer

These are super comfortable for long hours in the saddle. I've owned 2 pair for 3+ years & they've held up well after many miles & many washes. The only bibs I might replace them with would be the new s7's.
