This jacket is the first motorcycle jacket I have purchased. I am 5'5" and 125 lbs. I got a size 44, but probably could have gone with a 46 for layering. Like the previous review stated, the arms are snug. I bought this in hopes to wear a sweatshirt underneath for some cold weather riding, but its definitely a tight fit. On its own, the jacket is perfect. I know come spring and summer it'll be great once it has had the chance to break in. If you are planning to wear any other layers underneath I suggest sizing up. The padding sits well in the elbows and shoulders. And the leather is very durable. Good quality jacket all the way around. Doesn't cut in real tight at the hips like most womens riding gear either which is nice!
I splurged on this jacket as an upgrade to my current Bilt textile jacket (my first motorcycle jacket ever). I ordered this in a size 42 and it fit perfectly! For reference, I'm 5'2" and 125 lbs, 36B and 28 in waist. The sleeves are quite form fitting but on the long side for me. Thankfully, there are zippers at the end of the sleeves near the cuffs so I can adjust them to get my gloves on, etc. The leather is a bit stiff when I tried it on right out of the box, so I docked 1 star for that, but I imagine that it will break in and become softer with a few wears. The material is high quality and the jacket is well made. Seems very durable. Armor in all the right places with good protection in the back, shoulders, and elbows. Inner pockets on both sides including a waterproof zippered pocket on the inner left side. Very pleased with my purchase!
