With fall nearly upon us, crisp walks are on the agenda. You'll need a lightweight jacket to grab on the way out the door, whether you're headed around the block or to the gym. While there's certainly no shortage of workout jackets on the market, few are actually flattering — and fewer still are affordable. Luckily, this Amazon No. 1 bestseller checks both boxes — and guess what? It's on sale for just $21.

Gihuo Athletic Full Zip Lightweight Workout Jacket

$24

This zip-up will keep you warm on chilly mornings, but is still lightweight enough for those warm early autumn days.

The Gihuo Women's Athletic Lightweight Workout Jacket might look like an average zip-up at first glance, but Amazon reviewers swear it's anything but. For starters, it has plenty of high-end details, despite being a steal: It boasts a tailored silhouette, curved hem and thumbholes. The magic is in the fit: It offers the right amount of compression while still being comfortable, and because of the cropped length, it automatically cinches in at the smallest part of your waist.

The jacket is available in 11 colors and ranges from XS to 2XL. Because of the slim fit, some shoppers suggest sizing up for a bit more wiggle room, though if you want to reap the full effects of the tailor-made style, go with your regular size.

Over 2,400 reviewers gave it a perfect five stars. Most importantly: Shoppers promise this jacket is an instant confidence booster.

Says one: "Makes me look bomb and curvy... I feel hot in this jacket." Another adds: "Makes my waist look unbelievable!" A third chimed in: "This jacket makes you look snatched! It’s comfy and so flattering."

One potential downside? You'll need a backup or two — considering the amount of time you'll spend wearing them. Says one shopper: "This jacket is so comfy and flattering, I don't think I'll ever take it off!"

If you have Amazon Prime, you’ll get free shipping, of course. Not yet a member? No problem. You can sign up for your free 30-day trial here. (And by the way, those without Prime still get free shipping on orders of $25 or more.)
