Top PopFlex Athleisure Apparel:





When Cassey says she created the perfect tee, I think it’s safe to say she indeed did. When shopping for the right fit, t-shirts are often too boxy or not comfortable against your skin. The design on this one is flowy but not too much. By creating a back center seam, the material sits on your frame like it was tailored for it. The material is rayon and spandex for a flexible buttery soft stretch, and the hem of the shirt is arched with longer sides to compliment your silhouette as you move. The ribbed crewneck and fixed double-rolled sleeve hems prevent that weird fabric flip when you’re working out or just lounging around the house. You can wear it underneath a stylish coat to work and pair it with leggings for a gym workout or a lounging stay-in. It comes in eight neutral loving colors with a three-tee bundle option.

You know of the Perfect Tee – meet the Perfect Boyfriend Tee! With all the seamless fit of the original, this one has a little more length and bagginess for a more comfy fit. It’ll still flatter your body with a flowy boxy fit and cover your behind if you prefer longer tees when doing those epic leg days at the gym. The back center seam still gives you a feminine silhouette without being too restrictive in shape. This one comes in black, white, and gray, as well as a trio bundle set if you can’t wait to get comfy in all three.

A quality tank top is as simple as it is notoriously difficult to find, and this version is versatile and complimentary to every body type. Not Your Typical Tank is great for wearing as a layering piece underneath a jacket or hoodie and on its own with your leggings or baggy jeans. It has a crisscross design in the back that keeps the form-fitted, while the keyhole in the back gives a chic and breathable look. The front neckline is a high scoop that keeps everything in as you work out or lounge around. The fabric is a wide-ribbed rayon and spandex blend for soft and flexible wear to knot it as a crop top or tuck it in with cute high-waisted shorts.

This City Crop Tee is 100% cotton and 100% reversible. The crewneck tee is a stellar layering piece with fabric that’s not too hot and a reversible bow that can be tied in the front or back whenever you want to switch up your style. The hem sits at a cropped waist length, so it pairs great with high-waisted or mid-rise leggings, and its cap sleeve so you’ll have flexibility in movement at the gym. Simple enough to throw over a sports bra and cute enough to wear the brunch in the city. It comes in three neutral colors – white, black, and rose taupe – with a three-tee bundle available if you’re already thinking of the possibilities of where to wear them.

We love a peek-a-boo moment! The Explore Tee is a crewneck tee with an open back cut out that is truly a party in the back. The fit is flowy and relaxed, so you’ll feel comfortable lounging or running to your next yoga class. The rayon and spandex combo are unmatched when it comes to the soft and flexible material of these tees, and you’ll want to explore everything around town in these because of it. You can get these in a three-tee bundle and one of the five colors: white, black, oatmeal, taupe, and heather gray.

As a genuinely customer-forward brand, POPFLEX Active designed this bralette in response to the overwhelming feedback for a sports bra with built-in non-removable padding that won’t warp in the washing machine. The Celeste Mesha Bralette has a contoured underbust detail and criss-cross back straps to support you from studio-style workouts like yoga, Pilates, and more to brunch with friends. The racer front design is sporty, while the contoured mesh adds a feminine touch to your workout. You can choose from three neutral-tone colors: black, coconut cream, and leafless tree (a cool brown).

When you want to show off your new sports bra but don’t want to go completely shirtless, this Daring Deep V Tee is an excellent choice as your new go-to gym workout top. It plunges into a dramatic deep V-neckline (roughly just between your navel and your sports bra band) and lays on you comfortably as a flowy oversized tee. The back center seam means less irritating lines, and the ribbed neckline lays flat. It comes in three lovely neutral shades: White, Black, and Lilac Haze. 


A fitness dress that looks cute AND comes with pockets? Sign me up! As one of her most popular requests on social media, Cassey Ho created this PopFlex Active dress with the gym girlie in mind. Proving you can combine style and function, this dress has built-in shorts with pockets on both sides and a supportive padded shelf bra. She also created a waist-snatching drawstring to give you that hourglass shape with room to breathe. The ButterSmooth Brushed fabric and the front U-shaped neckline keep the girls in while you work out. The back is low for breathability, and the circle skirt makes you want to twirl all day. It comes in beautiful colors like Moss, Coral, Pink, and Country Blue.

I never thought I’d want to work out in a onesie – until now! This workout jumper is a one-and-done if I’ve ever seen one. As one of her most popular back-by-demand pieces, the Peek-A-Boo Onesie is a stylish and form-fitting active jumpsuit with an elegant square neckline with peek-a-boo hole for breathability and a low X-back design with adjustable shoulder straps to customize to your liking. It comes with deep side pockets (because, of course, it does!) and has a V-booty lifting back seam to support your bum as you squat. It’s great for the gym, yoga, errand runs, and lounging around the house. It comes in stunning Deep Clay and gorgeous Deep Jade colors.

High-rise leggings have been my go-to lately, and these are definitely on my New Year’s list for starting a new gym routine after the holidays. The newest CrissCross Hourglass Leggings (and most viral on TikTok) give the shape and wear you’re looking for with an enhanced V-cut waistband that doesn’t dig into your stomach but still gives you a holding shape. The deep pockets are what every girl needs (and has been asking for forever), and the anti-camel toe seam-free front panel is a godsend. It has that ButterSmooth Brushed fabric with stretchy softness you’ll want to wear beyond the gym, and inseam lengths available for us tall girls, too!

Flared pants are back, and I’m not mad at it! The Crisscross Hourglass Flared Legging was requested by many in the PopFlex community, and Cassey Ho delivered (per usual!). You still get the pinch-free crisscross waistline, buttery soft fabric, anti-cameltoe front panel, V-booty back seam, and deep pockets (with bonded seamless edges) – now, you’ll also have flared hems that you can work out in or wear to go out. There are also inseams for taller girls, so check these out if you want pants that look as nice as they feel with flair.

If you aren’t a superfan of the Twirl Dress but still want to twirl around every once in a while, this Crisscross Hourglass Twirl Skort may be the ticket. Taking all the best design features and rolling them into one, it’s no surprise this PopFlex Active skort went viral. The now iconic crisscross waistband pairs beautifully with the circle skirt, and the anti-camel toe front panel in the shorts underneath goes perfectly with the deep pockets we all know and love. The neutral colors of white, light lilac, and rose grey go with everything, so you can mix and match your style.

If you enjoy working out or lounging in shorts, these curve-loving booty shorts were meant for you! Cassey Ho combined the always popular high-waisted crisscross waistband along with the seam-free anti-camel toe front panel plus highly requested deep side pockets into their curve-loving biker shorts you can enjoy during a workout or just lounging at home. The V-shaped booty lifting seam perks your backside while the anti-pet hair and squat-proof fabric prevent showing the world what you don’t want them to see. You can choose from colors like Black, Smokey Grey, and Peppercorn (brown).

If you prefer more length in your shorts, these Superscult Biker shorts are worth a try! With a 7-inch inseam length, you’ll still get the seam-free anti-cameltoe front panel, V-shaped booty lifting seams, and squat-proof fabric. However, the pinch-free high-waisted band lays in a straight line (not a criss-cross) design. The smooth material is also anti-pet hair and comes in Black, Smoky Navy (dark navy blue, and French Roast (rich brown).


Cassey is known for adding a touch of whimsy to her designs, and her PopFlex outwear is no different. The Whimsical Breeze Windbreaker is a lightweight layering piece for any early morning workouts or tossing on when the weather turns as you run errands. The dramatic ruched sleeves still look sleek as the arching princess seams on the front and back give you a slight corset-like shape. The oversized and boxy shape is intentional to allow layering and breathability, while the slightly cropped hem sits at the waist for a fitted look. The dropped shoulder gives comfort all around, and it is a full zip front with an adjustable bungee waist cord. Choose from five beautiful colors: Foret Night, Desert Sand, Blue Ice, Blush, and White.

This Faux Sherpa Cocoon Coat is truly romance in a coat. Everything about this coat gives life in the dead of winter, from the length to the fit to the comfort to the hood. It hits just above knee length and has thumb holes on the sleeves (I know!), so you’ll stay warm all over and all season. It comes with an oversized hood that feels like you’re wrapped in Christmas, while the pockets on both sides could probably fit a gift or two in them. The vegan leather trim has a faux horn toggle at the front for an authentic winter wonderland look. It’s a great layering piece and comes in neutral colors that pair well with every outfit – a gorgeous Cream and beautiful Black.

Hoodies are a pop culture mainstay, and this one may have elevated the game. As Cassie says, “it’s like wearing your boyfriend’s hoodie, except baggy in only the right places.” Touted as the ultimate marshmallow hoodie, the Pullover Cloud Hoodie is a luxuriously soft blend of their proprietary Cloud Fabric. It’s thick enough to keep you warm and cozy while lightweight enough to wear anywhere, anytime, for any reason. The extra-large hoodie comes with an adjustable drawstring and is handy for any bulky headphones, hats, or hairstyles underneath without restriction. The blousy sleeves and dropped shoulder give a comfortable fit as the front kangaroo pocket holds everything you need. Get yours in all five colors: Pink Lilac, Smoke, Heather Grey, Denim Blue, or Milk Tea.

As my personal favorite PopFlex athleisure launch of 2022, this Zip Cloud Hoodie has been winning people over in droves. The super oversized marshmallow hoodie is everything you love about the Pullover Cloud Hoodie, with a full zip front closure for easy on-the-go or lounging-in wear. The triangle shape of the hoodie gives it a fitted silhouette with a baggy look, and the oversized hoodie gives it that enchanted feel Cassie loves adding to her pieces. You can get it in Heather Grey or Taupe right now but get on the waitlist when they restock other colors like Chestnut (my favorite!), Blush, Smoke, Black, and Blue Steel.

The Half Zip Warm-Up Hoodie is great for a pre-workout walk or post-workout stretch. The oversized fit is cozy in every way, while the dropped shoulders and blousy sleeves give comfortable flexibility to move around as needed. The extra large kangaroo front pocket tunnel has zippers to keep your valuables and workout essentials from falling out while you run (or lay around – no judgment). There are even adjustable side bungee cords at the hem that you can use to adjust the fit or style into a crop top hoodie, and the back pleats give that roomy, structured look. You can get this best-of-both-worlds hoodie in Latte, Black, Heather Grey, and Light Heather Grey.

The perfect crewneck does not exi…oh, but it does! Too many of us have experienced the not-so-flattering crewneck sweater that’s barely any warmer than a long sleeve t-shirt. Cassey Ho designed this loose-fitting crewneck with a dropped shoulder for a slouchy vibe and blousy sleeves for an ethereal feel – plus the ribbed sleeve cuffs adjust to around your hands or wrists. The incognito side pockets are the true stars of this show because…who doesn’t love pockets?! You can go from an early morning warm-up to a boozy brunch to running errands with style and comfort.

POPFLEX Active’s most popular Pullover Cloud Hoodie + the fabulous Faux Sherpa Cocoon Coat = the new Faux Sherpa Pullover Cloud Hoodie! It’s the best of both worlds with the extra large hood size along with the warmth of faux Sherpa fabric in one comfy oversized fit. The luxe blousey sleeves and dropped shoulder design we love are still front and center with a kangaroo pocket to hold your stuff (or your own hand when you’re feeling lonely). The ribbed bottom hem hugs your waist to keep the cold out and is slightly more cropped than their original Cloud Hoodie, so size up if you’re looking for that extra length in your new furry hoodie. 

If you’re in your soft girl era, the Ooey Gooey Mockneck Sweatshirt is perfect for you! As POPFLEX’s pinnacle “loungewear meets fashion” staple, this comfy yet loose sweatshirt with a mock neck collar will feel comfortable, not suffocating. You can have a matching set by getting the Ooey Gooey Lounge Shorts for the complete outfit. There are also hidden side pockets (because, of course there are!), and that dropped shoulder gives luxe and leisure vibes. The ribbed sleeve cuffs keep sleeves off your hands until you want them there. There are beautiful colors available including Black, Ballet Slipper (light pink), Light Heather Grey, and Bookworm Blue.
