Mille GT Half Short

Like with their bibbed brethren, Mille GT Half Short brings us a redesigned insert and graphics in the same quality fit we love from Assos. Like its predecessor, the Mille GT is the workhorse short from Assos, built for riding, training, and racing.

The Type.429 material, a durable fabric whose properties are a study in apparent contradictions, is another element of the Mille GT that has enjoyed flattering imitation. It combines a low-volume with moderately compressive supportive to keep both weight and muscle fatigue to a minimum. It also enjoys the durability of a ripstop material but with breathability, moisture management, and a comfortable touch that belies its hard-wearing nature.

Those already converted to Assos shorts’ comfort will notice a new colorway to their proven chamois construction. The change in color, from the amethyst purple to this basalt black, is an easy way to identify the latest insert. The Mille S7 EVO features the same 8mm thick memory foam with a 3D waffle upper, which increases airflow. The all-new kraterCooler system furthers ventilation through the short, with small perforations in the front of the insert to draw air through the foam. Like the previous S7 insert, the Mille S7 EVO also has Assos’ patented goldenGate construction, which interrupts the stitching along both of the chamois' side panels, allowing a greater freedom of movement in this sensitive, rotational area. To reduce friction even further, Assos extends the chamois' thinly-padded sides over this short-to-chamois junction, making the transition against your skin as smooth as possible.

The shorts are cut to accommodate a regular, athletic build and given that this is Assos you won't be surprised to learn that the shape is engineered so they fit best when you're in the saddle. While we can't speak for every cyclist, not all of us at Competitive are built like the rail-thin, razor-elbowed climbers of the pro peloton. The mille fit means that the shorts conform to our body with a gently compressive, second-skin fit instead of squeezing and pinching our legs into bulging shapes that range from unflattering to uncomfortable.

The leg and waistbands continue this theme of fitting your body instead of forcing your body to fit the shorts. The legs terminate in low-volume superFlat grip bands to keep the cuffs securely in place, and the waistband uses gentle compression and a wide footprint to ensure coverage without adding pressure and restriction to your stomach.

  • Cycling shorts for endurance rides and long training days
  • More forgiving waist fit adds comfort to performance
  • Gently compressive Lycra for confident support and stretch
  • AEPD fit wraps muscles rather than formlessly stretching
  • Redesigned chamois adds cushion without undue bulk
  • Elastic leg cuffs ensure fit without pinching
  • Assos has long been the leader in cycling clothing innovation

Note: Assos clothing has a very slimming, anatomic cut, if your build is less than slim or if you like your fit looser, go up in size.

How to Measure:
For best results, take measurements over your underwear.
Measure around the widest part of your chest.
Bend to the side and measure around the place where your waist bends, keeping the tape a bit loose.

my sizing experience

I have given up on finding an Assos Shirt that fits (too narrow for me), but thoroughly enjoy the 3 pair of their bibs I have, all in a size L. For reference, Im 42"chest, 33" waist, around 185 lbs with athletic build. At just over 5'-9", they are not too long for my somewhat short legs the way other brands sometimes are. I bought these to replace the other Assos shorts I owned until my golden retriever chewed a bullseye hole a very undesirable spot...haunting the person who was drafting me, before I realized the damage. Oddly, my experience has been that the Assos "shorts" are best worn a size smaller than their bibs. For this latest pair, I initially went with the Large (similar) to the bibs I wear, but found the chamois to move around too some of the other reviewers have reported. Thus, I passed them along to the (haunted) guy I ride with. I replaced with the Medium (same size as the damaged ones) and the fit is much better. I don't like these as much as the bibs, but do fit them into the regular rotation, and they are great for indoor training. YMMV, but my finding is to go down a size with Assos shorts.

I have never been able to use shorts on the bike. Most slip down after a short time on the bike and need constant reworking. These stay nice and form fitting around my butt which means the chamois stays pretty much in place. I've had about 20 rides with them so far and am considering wearing them for a cross country trip. The chamois is a little thin at 8mm but not too bad. I use a brooks saddle so don't need a lot of padding but I like a nice tight fit with the shorts which these provide. The waistband does it's own thing, sometimes staying up and feeling good and sometimes rolling down and feeling uncomfortable but overall these are usable. I ride hands free sometimes and have perfected the ability of pulling the waistband up so there you go. Yes I would buy another pair though I would probably by a size smaller next time.

I agree David. I want to love these shorts, but they require constant reworking on my end. I think I will go with Rapha shorts!

mois did not live up to expectations. The 'cuffs' and waistband are very comfortable for long (100+) rides and the material makes the shorts disappear. However I was disappointed with the comfort of the chamois. A bit to much movement and for long rides maybe a bit more depth would benefit this short's comfort
