I browsed through the reviews to decide what size jacket to get, then I found a reviewer with the same height and similar weight like me posted a photo of themselves in a medium. So I got myself a medium in black.

I'm 5'2", 102lbs, and 34B. I bought a medium to go along with the pair of Colombia's Storm Surge rain pants (x-small) for when the rain comes in Southern California. I enjoy how roomy and light it is, and I can wear several layers underneath when the weather demands it. When it rains, the water rolls straight off of it and keeps me dry.

The sleeves have adjustable Velcro cuffs, and it goes pass just the tip of my fingers. The mesh-lined jacket itself almost covers my entire butt, but my rain pants can take care of the rest. The storm hood and waist can be easily adjusted with the elastic cords found there. I often wear a cap whenever I go out, and the hood covers it except for the very edge of the bill/visor, so I often find it damp/wet, but not a big deal. The main front zipper has a flap that can be secured with Velcro to keep the water out. The two pockets has flaps and zippers as well, and the insides are mesh-lined and are big enough to fit an entire 16.9 fl oz water bottle, or my iPhone 6 Plus with its Otter Box Defender case on with some room to spare.

I highly recommend it for any kind of rain except for really heavy rain like a monsoon.

Pics included, and sorry for the blurred out face and bathroom...

I didn't check the size chart - I'm a regular Medium pretty much everywhere so I just ordered that. I'm 5'10", 155 lbs and it was huge on me. I returned it and got the Small and it fit much better, though the sleeves are still longer than I'm used to. Can't hurt in the rain, though. The jacket itself seems well constructed though I can imagine the mesh pockets wearing out or ripping pretty quickly. There's a cool feature where the jacket can be rolled up and shoved inside-out into one of the pockets and zipped up (like some reusable shopping bags) if you're trying to save space in a day pack, which I'll definitely appreciate down the line. All told it seems like a solid jacket for a good price. It's not thick btw - just a shell to keep the rain off.

I am very impressed with the quality of this jacket, it looks very elegant and I've gotten compliments on it already. Definitely will be buying more in the future!

Had this jacket for about a month now and all I can say is it's awesome! Perfect for rain and a pretty damn good wind breaker as well. I can't say it's completely waterproof because I haven't been in a monsoon rainstorm but it's kept me dry for every other rain storm. Also it packs up so if you don't need it right now but maybe later for like a camping trip or something you can pull it out and put it on.

Instructions: the left pocket has a label inside that says "packable" turn that guy inside out and stuff the rest of the jacket on in there.

About the size of a normal picture 6"x4" and the width of maybe 3-4" probably depends on how well you stuff it in there. Hope this helps!

Excellent seller & product
