Love this - wear it all the time

I think this is the one piece of running apparel I wear the most. It looks good, it's super visible, really comfortable, and I love the zip pocket. My guy friends are jealous and request a men's/unisex version. Also great for commuting to work by bike, walking with friends, etc. Multiple drivers in town have thanked me for wearing it. Awesome gift.

Highly reflective and great versatility!

I used this for the first time on my run this morning in humid weather before sunrise. I wore it alone over a sports bra due to the humidity, but was concerned about possible chafing since it’s a hit short on my long torso. It was no problem at all! I was also surprised by the breathability of it given the reflective material, but the perforations really do their job well. As you can see in our home security footage of me leaving this morning, it’s super reflective, too! I felt very safe on my run before dawn this morning thanks to this lightning layer! For reference on fit, I’m 5’8”, 140, size 6, and I purchased a S/M. Great fit.

Best Running Investment

This vest is FIRE! Seriously. I run early with my run club and they comment every time I wear it how visible and bright I am when cars are approaching. It's lightweight and easy to throw on over 5 layers in the winter or a sports bra in the summer. This piece is great quality and adorable. Probably one of the best pieces Oiselle has put out there.

Make Yourself Seen

I've worn this over a bra, tank, long sleeve, and even my hydration vest! I have the L/XL. Normally I wear a L or 10 in tanks. Yes, it looks crazy when I wear it over my hydration vest, but I can still access the pockets in the front as well as my water, and when the sun comes out, I stuff it into the back of my vest. Normally I don't like being noticed, but when it's dark out, being seen is a must! I am buying a second one because I end up wearing mine multiple times before washing. Hey, I'm an early morning runner and can't do laundry every day! Sometimes I pair this with the Firecracker tights or shorts but often I wear this as my only reflective clothing because it's bright enough. Highly recommended if you run in the dark!
