I do agree with the other review that the description on size is misleading. However I tried a small and and medium. I'm 145lbs with muscles and the fabric on the should and chest stretches comfortably. I ended up getting the small as the medium bunched up too much on when in cycling position. The Jersey is very comfortable and the side zipped pocket is excellent. The side material does a great job venting. Note that for their other jerseys you will need to size up one like the description says just not this one.
This is the second pair of Sportful bib shorts. My first was the Giara.
Firstly, the good. The shorts have good compression and the chamois is comfy for longer rides. I like the feel overall for shorter rides.
The things that I feel can be improved on are a deeper thigh pocket. It's fairly shallow, and struggles to keep my phone secure when vertically positioned. The big drawback for me are that the straps are like cheese graters for your nipples. They're very short as well. Bibs at this price have no excuse for cheap, overly thin and tight straps.
I'm a size large in every other brand I've owned, and learned quickly to ignore the sportful sizing and size up. Even in an XL, these straps feel like they're inches too short, with too little stretch making for a fairly uncomfortable fit on the shoulders and as previously mentioned, my poor nipples. I'm trying to figure out how to permanently stretch the straps out, but to no avail, yet.
If you have a shorter torso, I'd imagine this won't be a problem. I'm 6'4" 185lbs. I'm tall, but pretty damn thin. I'm figuring out that Sportful may just not be the best fit for me.
