Meet the Chic Sportswear Brand We Swear By for Colder Months

There's one brand in the activewear space that we cannot get enough of lately. It's been at the forefront of some of our favorite fall looks (for workouts and beyond) and just gets better with every new arrival that hits the site. And if you're already thinking of On, then you're right on the money. I first heard of the brand through an editor atBest Knockoff Luxury Clothing who wore the running shoes, and since then, it seems like fashion girls can't stop talking about how much they love it.

With the winter months coming in hot, we tapped three stylish and active content creators to give us the lowdown of the specific pieces from On they're wearing as the temps drop in their cities. Meet the Performance Winter Tights, a windy-weather-approved staple that Chicago runner Avery Lauren swears by; the Challenger Jacket, an exceptionally cool puffer worn by Los Angeles local Averi Frith; and the Weather Vest, a must-have layer for in-between days that Georgia native Lauren Chambers can't live without. Not only are all three pieces great for every winter climate, but they're ridiculously cute. Keep scrolling to see why each cold-weather-approved piece deserves a place in your rotation this season.

"I typically prefer my activewear to be as lightweight as possible, but those thinner leggings obviously don't stand a chance against the Chicago winter. So I love the On Performance Winter Tights because they are the only leggings that I trust to actually keep me warm on my outdoor runs in the cooler temps. They also get bonus points for not falling down while I run! They have the perfect amount of compression. I think layering is key for running outdoors in the cooler months, so I layered the crew-neck (which has zippers on the sides to adjust the fit!) with the Challenger Vest so that my core is extra warm but I still get a nice breeze on my arms and don't overheat." — Avery Lauren, content creator 

"As soon as I saw the Challenger Jacket, I knew I had to have it! It is super sleek while also being really functional. It's breathable but keeps you super warm on those chillier days that we have in the mornings here in L.A. Plus, it just looks good. (Oh, and bonus points for the thumb holes!) I'll usually do a hike somewhere with a light jog and inclined walking in the winter, and this is the perfect layer. It works with so many things I own, but of course, you'll find me pairing it with my other On pieces." — Averi Frith, influencer 

"Now that the temps have dropped in Georgia (hello, fall!), the On Weather Vest has been a personal favorite. It's lightweight enough to not feel bulky or hinder my run, but it keeps me warm during those later afternoons. I'm that girl who has more activewear than *regular* clothes. I live in a sports bra + tights combo almost daily, so it's important to me to have high-quality activewear that I can wear for everything from a run to running errands, and that's why I love this look. The performance tights and sports bra keep me supported during my workout. The Cloudstratus 3 sneakers provide comfort for busy days." — Lauren Chambers, content creator
