That said, I have been on this same mission this fall. I borrowed one at HGF so I wouldn't have to wear a jacket over my team jersey. 42 at the start, 60 ish by the end. Worked like an absolute charm. Yes, I was slightly overwarm by the end and a little sweaty, but not boiling hot or drenched, and overwarm works better for me than underwarm, and just arm warmers would have left my core cold with the 20mph winds that day.

So when I got home, I set out to buy one. Talk about a frustrating endeavor.

I found that bike shops don't have much in stock and I got tired of going from shop to shop. Surprisingly, sporting goods stores had nothing! The Nike store had nothing! The addidas store had nothing!

I found some Nike dri-fit, both crew and quarter zip, that were reasonable on weight and semi-windblock (which is all I really need) at JCP and Kohls. Bought one, but the smallest they make is a S, and it's a loose fit S, which looks sloppy and ill fitting under a tight jersey sleeve.

I found some Nike-Pro dri-fit at Marshalls... S is SMALL. Compression fit small. Perfect. But they're slightly less thick, and I only found one orange one. I intend to stop at more Marshalls this weekend (I have some other errands to run that will get me near 3-4 stores) because I want to pick up 2-3 more.

I think the Craft sounds about perfect, but with as much variability in design, weight, and FIT, as I've encountered in this search, I'm not willing to buy online sight unseen.
