Excellent jersey that works best in warm to hot conditions and I primarily reach for this jersey in the sumemr months. However, I have ridden this jersey with a base layer into the high 50s and remained comfortable. I am 5' 11", about 177 lbs, with a 40R chest. I purchased a size XL and it works well for my preferences. I could have fit into a size L due to the stretch fabric if I wanted a tight race fit. The fabric breaths very effectively and is very comfortable. To be honest, one of the big selling points was the excellent choices in bright, solid colors. I have both the vivid orange (my favorite color for visibility) and the red and I am very happy with the purchases. These jerseys are a very good value when the jerseys are on sale.
After trying several different bibs, I decided on these. The price appears reasonable, the chamois quality is comfortable and supportive, and the material is generally of good quality. The pockets are particularly convenient, with one on each side of the leg, and are ideal for carrying gels or power bars.
In my opinion, these are an excellent choice for gravel or road cycling.
For reference, I am 5'10" and weigh 172 lbs, and I ordered two pairs in a large size.
My 3rd pair of Assos bibs (3 different models), so it's certain I'm a fan of their products. I'm 6'0' / 137 lbs / pretty old. I've gone with medium in GT Mille bibs before. I really like the fit and compression of the mid thickness Lycra and the mid length (lower than most bibs) front panel (easier than most for quick urination break). These have a similar fit (again I like the compression) but a thinner (summer weight) Lycra. The chamois is different / thinner than Mille GT series but still quite comfortable (the longer the ride the more I'd choose thicker chamois). The leg length is better for me, but I wouldn't consider it long (more like normal in other brands). A go to summer bib.
I've found these tights very versatile when cycling in the high 30s (F) and into the 50s. They've kept me warm in the high 30s (as cold as I've worn them), are breathable preventing that clammy, sweaty feeling, and have been comfortable in the 50s without overheating. I wear them over padded cycling shorts. I like the elastic waist tie, although the waistband is secure without it.
The only minor negative for me is that they seem a bit long for the waist size (XL). However, they're not long enough to return (better slightly long than slightly short), I'd buy them again (and probably will buy a second pair), and I'd recommend them to a friend.
These tights are a good find.
