MILLE GT Summer LS Jersey

A long-sleeve summer jersey might seem like an oxymoron, but that might depend on where you ride and what the conditions are like. If your local climate has ever-changing weather conditions and you're looking for a high performance, moisture-wicking, and breathable jersey with a little more coverage, the MILLE GT Summer LS Jersey certainly fits the bill. It offers additional protection (UPF35) against the sun's rays and can provide a little extra warmth on those cooler starts while using the same quick-drying and breathable Stripe fabric that's used on the short-sleeve version of this jersey.

We certainly see this as more of an early or late summer piece, and maybe even for spring or fall with a base layer, depending on where you live. It's remarkable just how well this jersey wicks, dries, and breathes when the pace picks up or the temps rise. The innovative Type.157 Stripe Tex fabric consisting of a circular knit is what's at work here and lets it get away with being a long-sleeve that we're tempted to wear when otherwise a short-sleeve would be a no-brainer. And at any point, if the buildup of heat is just too much, a slim-full-length zip lets you quickly dump heat and zip it back up, adjusting easily to the conditions. The jersey features the Mille Regular Fit cut with raglan sleeves making it more relaxed than its all-out Racing Fit jerseys so it's highly suited for training rides where comfort trumps aerodynamics.

We've really grown to love the Triple Ramp concept rear pockets, which positions them perfectly for ease of access and preventing the dreaded droopy rear jersey. This concept places the seams internally making the pockets barely noticeable and when you fill them with ride snacks and tubes, the top of the pocket forms a lip keeping items in over rough roads.

  • A long-sleeve jersey for cool summer days and extra UV protection
  • Mille cycling fit is ideal for training ride comfort
  • Type.157 Stripe Tex wicks sweat, dries quickly, and breathes
  • 3 roomy rear pockets fit ride fuel and spare tubes

Sleeves too short

  • Familiarity: I returned this product before using it
  • Size Bought: medium

Long sleeve summer jerseys are a rare beast, so I was excited to try this out. I'm 6ft, 150lbs, and got the medium based on the size chart. While the fit overall was great, the sleeves are an inch or two short, which would leave a gap between the arm and my gloves. For a jersey whose whole point is to keep the sun off my arms, that's not going to cut it. Seems like it would be a good jersey for people with shorter arms or who can fit a larger size, which presumably has longer sleeves.

Great jersey; why can't others make one?

  • Fit: True to size
  • Size Bought: L

Hah; because the others are not Assos ! Everything I have from Assos is fantastic and does just what it's supposed to, and to perfection.! I've been riding/training with Assos gear exclusively for years now; this piece is no exception. i have an older Mille LS jersey and it was a bit 'blousy' in my usual XL size (I'm 6'2" 168lbs) so I thought the L size would be better, but it's too small.. It is a different material and different cut as well, so I swapped it for the XL, which is perfect. - no bunching, no flapping, but also no binding and feels slippery through the air. It also wicks like a demon and is cool even in the warm Florida (humid) air. Base layers are essential (to the reviewer who had not use a base) and the right base layer to suit the conditions will make the whole system perfect - not to hot or cool and always draw moisture away.. I couldn't be happier!! Maybe better colors could be my only beef, but hey, who's looking.. The best thing is the sun protection for arms; no need for arm sleeves.

Fit comments.

  • Familiarity: I've used it several times
  • Fit: Runs small
  • Size Bought: Medium

The size medium fits me perfectly even though I'm between a small and a medium on the size chart. Some have commented that Assos is tight in the chest. That is true when standing up. This Jersey is designed to fit when riding and the fit is perfect in that position.

The Perfect Long Sleeve Summer Jersey!

  • Familiarity: I've put it through the wringer
  • Fit: True to size

I am a fair skinned person and I always cover my arms while in the sun. I purchased this jersey for an alternative to summer arm skins. I like this jersey because the arms are trim, not tight against the skin, allowing for movement and air flow. Now, I prefer this jersey to arm skins and I plan on purchasing a second one. My original purchase was the blue one and I have had more compliments on this jersey than any one I have ever owned. The 3 pockets are large and the safety flap in each one can keep a cell phone inside in the event of a tumble, just not like a zipper pocket. I use this jersey for road and gravel. The color is fast and the material is high quality has not snagged. This is not a stretch to fit all jersey. Great for cool mornings here in Central Oregon when paired with a wind vest.

I agree with your assessment.

Very Good

  • Familiarity: I've used it several times
  • Fit: Runs small

My first Assos jersey and expensive enough to qualify as an "investment". Material is very thin but that's what i was hoping for - bought it to use on rides in the Florida summer. Have not used a base layer with it but will consider that to help with sweat wicking and maybe make the jersey last longer. Fit is definitely Euro as you expect w this brand. I'm 5'7" 162 lbs 40-in chest 34-in waist and the Large has not one millimeter to spare. Fits weird when you're walking around but fits great when you're leaned over the bars on the bike. Nice not to have to put sunscreen on my arms before riding. Looks pretty stylish too but my goodness it is pricey!

Great Jersey

  • Fit: Runs small

Good quality you expect from Assos. As all Assos jerseys, it fits small and is most comfortable when in riding position. In terms of fabric weight, this is definitely a summer jersey.
