Yes, I think you're doing the measurement wrong. I am 6'0" tall and 24" from the CORNER of where my arm meets my shoulder (like where a shirt seam would be) to my wrists is plenty long enough.
I have two pair of these, and love them--would never wear a full-length pair skiing again! I'm 6'00" and 165lbs, and size Large fits me--I'm usually borderline Med or Large so I guess they fit a tad on the small side, but not alot--they're supposed to fit snugly as a base layer. My only complaint is how high-waisted they are--they come to my natural waist. But hey, with skiing that might be better anyways.
For Icebreakers, the lower the number, the thinner the weight.
True to size. Great material, lining, pocket, and overall manufacturing. But the waist is pretty tight, I guess that's because the rise is pretty high (more of a natural waist pant). I don't mind since I usually have a layer underneath, but if I don't the rough waist edges can really bother my skin. If you want a mid-rise or low-rise pant, look elsewhere. I am 6' tall and the Long length is great!
Didn't want pant seams inside my ski boots, so I bought these, and they're great! Soft, warm, and thin, so they layer great under my (rather loose) ski pants and socks. The rise isn't low (more of a classic rise), but I don't care cuz no one sees them. And it's an eco-friendly manufacturer, which I dig.
