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.

I purchased this in a S/M in the black color. It's incredible. I didn't even realize this was a clothing item I needed, but now it's indispensable. Granted, probably not one of my Oiselle items that will move into casual wear (haha) but it's super breathable, makes me crazy visible to passing cars, and once it's on, I don't even remember I'm wearing it.

LOVE this vest, the design, and reflectivity/details. Tops I am 6/8/10. Tried the SM/Med, was too short for my liking in my torso, yet still loose enough to wear a tank underneath. Will order in L/XL for better fit to cover my torso.

I have never been much of a reflective item wearer, but with the dark Seattle mornings, I decided it was time to take the plunge and get this for safety reasons. I was unsure if wearing it over a long sleeve would leave me feeling like I was suffocating on runs, but it performs extremely well. The side pocket is an extra plus for holding a key or gel! For sizing purposes, I am 5'9" and weight 135 and got the S/M. There was still a little extra room, but with the drawcord to cinch it at the bottom, it was perfect and did not move at all.
