True to size , I got a size small. With the time change here in LA, I decided to get this too in hopes to get some reflective gear for safety, and let me say I LOVE THIS TOP! My team mates said it was really reflective and cute. It didn’t bounce (which I was afraid of) , the material is durable , light, and airy. Can’t wait to purchase more!

It's nice that there are a lot of pictures of models with different sizes, except there are a ton of women wearing sm/m and one wearing a 1x/2x. There wasn't any model wearing a large/xl. I ordered a sm/m and I'm 140 pounds 34c. It's a little tight around my shoulders, then plenty big in the waist and it has a draw string. I almost should have ordered a l/xl which would have been nice to know with an updated size chart or with models wearing that size. But the actual reflective aspect is amazing!

Have been looking for a comfortable vest that was reflective. Found this vest and order a SM/MD and it fits perfectly over a long sleeve shirt and I can tell in winter when I have a jacket on it will slip over nicely. Has a nice side pocket you can get to easily to store your gloves/fuel, etc but the best part is everyone sees me coming. Ran with my running friend the other day and wow she couldn't believe how much it lights up. Perfect timing for the shorter days and early morning runs. Thanks Oiselle!

If you run early in the morning or at night, this is the best top ever! It is truly as reflective as it looks. I have an older version in black, but worried that I needed some bright colors as it started to get lighter in the morning. Someone at Oiselle must of heard me thinking this (it was literally just the other day) and what do I see the crackle! Yes! So just ordered! Thank you Oiselle!

No more dayglo orange oversized vests - this is a great product!

Love this! It's so bright and makes you extra visible during nighttime runs. The material is stretchy and comfortable. I'm 5'4" and 120 lbs, the S/M size is fits over other layers in cold weather.

I have the original version of this top. I wore this for the first time during my night leg for TIR (Texas Independence Relay) I got so many comments about how bright and awesome it is and a number of women asking where I got it. Being in Texas, I run super early to avoid the heat, and will wear this by itself (though it layers very nicely). Its bright, I feel seen and safe, even when i have to do an early stroller run with a non-sleeping toddler. I normally wear a M or a 6 and the S/M is perfect

I bought this for running in the dark in NYC, as well as for trails, but I have also found it very useful for biking in the city. Having the additional reflective panels makes me very visible to vehicles, other bikers, and pedestrians. The top is light, isn't bulky (fits easily into my bag so I can take it along with me to work), and fits over my tops easily. I highly recommend this for anyone who wants/needs to be seen.
