I have purchased the Assos Arm Protector in white and black. During a minimum of 200 miles of riding in the Santa Monica Mountains, they provide full sun protection to my arms and kept my arms comfortable in temperatures between 60 and 90 F. I use the white arm protectors on hottter days as the black absorts more heat. Since I ride quickly, I generally have a cooling effect from the air passing by Assos has design these arm protector to shape comfortly to arms and be form fitting. These arm sleeves are pricey but I have found Assos quality stuff lasts a long time. They come in 3 sizes: 0, I, & II. Take your time to be sure the size fit your arms to achieve the proper size.
When I see Assos using the word Mille in the product description, I think "relaxed fit". That would be appropriate for what is described as an endurance jersey, would presumably prioritizes comfort. The fit of this jersey is in no way relaxed, it is well made and comfortable but the fit is very snug, Equipe-level snug. I am not quite a race snake but at 145 pounds I am pressing the Small to its limit. I like the absence of a zipper at the waist but again taking it on and off is something of a project. That waist is a 30 so if you're over that you're getting a girdle. All that sounds a bit critical, but I like the support and I don't notice it when I'm riding, that is the most important bit. It also looks good, in addition to the slightly severe cut Assos is getting a little adventurous with color and I like it.
I did my first multi-day long ride last week. Day 1 was 91 miles, day 2 was 104, day 3 was 73 and day 4 was 70. So I bought the Assos Mille GTO bib shorts because all the reviews I read said they weee among the best bib shorts for this kind of use case. And they were right! Night and day difference between these an all the other bib shorts and biking shorts I had tried before. The only reason I didn�t give them 5 stars is I also bought a pair of Pearl Izumi Expedition bib shorts for the long multi-day ride, and I found them to be even more comfortable than the Assos. Of course, everyone�s butt/saddle relationship is unique, but this was my experience.
Got these on sale and have a few hundred miles on them. These are one of the most comfortable Bibs that I own now, or a close second to some Rapha Bibs that are on there way out. It's really about the way the chamois is designed. It has way less tendency bind the groin. This particular model has a ample thickness to the pad without feeling like a diaper like some Assos Bibs can be a bit too much, not these! They are a great summer weight with near to knee coverage which I prefer.
I got them in a Large Long, I am 73 inches and weigh 172. These are plenty compressive on the thigh for me. If you really like a squeeze a medium would have fit me too. Anyhoo, I wrote a review which means I'm really happy with these.
