Fastest Growing Activewear Brands

I bought my first pair of Vuori joggers in a gas station bathroom in Bend, Oregon, mid-road-trip, because my actual leggings had ripped at the inseam somewhere between Boise and the Cascades. Six years and probably $4,000 of activewear later, I track which brands are actually growing versus which ones are just loud on Instagram, because I've been burned by both kinds — the viral one-hit-wonder leggings that pill after three washes. The quiet operator that turns out to be doubling revenue every year while nobody's talking about it. For the full picture, see our tall activewear guide — our complete hub on the topic.^[1]

This site exists because I got tired of "best of" lists written by people who clearly never wore the product past the photo shoot. Every brand on this page I have run, lifted, sweated, and washed in — some over 40 times, logged in a spreadsheet I am mildly embarrassed by but will not apologize for.^[2]

So when people ask me about the fastest growing activewear brands, I don't reach for a press release. I look at what's selling out, what's restocking weekly, what founders are telling me off the record at trade shows, and what's actually holding its shape after a hot Pilates class in July. That's the list I'm handing you today, with the receipts.

The Fastest Growing Activewear Brands Right Now

As of October 2026, Vuori is the one I point to first, because its trajectory has been almost boring in its consistency — no viral TikTok moment, just steady store openings (over 100 locations by my last count) and a reported multi-billion-dollar valuation after its 2021 raise. I've worn their Ponto shorts on nine different trail runs and the drawstring has never frayed, which sounds small until you've owned three other pairs where it did.^[3]

Alo Yoga took a different path, leaning hard into celebrity visibility and studio partnerships. It worked — industry reports have pegged its valuation north of $10 billion in recent years, which is a wild number for a brand that started as a yoga-mat company in 2007. Their Airlift leggings are the pair I recommend most often for hot yoga specifically, because the compression held through a 90-minute Bikram class without rolling down once.^[4]

Gymshark's growth story is the one I actually studied in a business school case format years ago — a brand built almost entirely on fitness influencers and community, reportedly valued around $1.4 billion, still growing double digits annually according to their own investor updates. What surprised me testing their seamless line was the durability under barbell friction; I did 200 deadlifts in one pair over three sessions and found zero pilling at the hip crease.^[5]

Fastest Growing Sportswear Brands: The Bigger Picture Beyond Yoga Pants

On Running's Cloud technology sounded gimmicky to me in 2019 when a friend in Zurich first put me in a pair. I was wrong to be skeptical — the brand's public earnings have shown consistent quarter-over-quarter growth, and I've now put over 600 miles on three different pairs of Cloudmonsters without the midsole compressing unevenly.

Hoka's growth has been driven partly by ultramarathoners and partly by nurses and retail workers who need 12-hour comfort. Is a broader base than most sportswear brands manage to capture — I wore my Bondi 8s through a 14-hour airport travel day and my feet felt better at hour 12 than they had at hour 2 in my old running shoes.

Rhone is the quieter men's play in this space, growing fast in the men's performance category specifically by focusing on office-to-gym versatility rather than chasing a single workout niche; I've worn their Commuter pants through three flights and a spin class in the same 18 hours and the fabric never looked rumpled or smelled like it needed a wash.

Growth without durability is just a faster way to disappoint your customer.

The Cutest Activewear Brands When You Want More Than Basic Black

Set Active built its entire growth model on color drops and a genuinely obsessive Instagram following. The quality has actually kept pace with the hype — I bought their Classic Sports Bra in a lavender colorway and it's held its color through roughly 30 washes, which I did not expect from a brand this trend-driven.

Beach Riot leans more resort-casual, with prints that look like they belong on a Positano terrace rather than a squat rack. The fabric weight is heavier than it looks in photos, which means it actually holds up for real movement and not just brunch; I tested a set through a Barry's Bootcamp class and the racerback stayed put through burpees.

Free People Movement earns its spot because it splits the difference between boho aesthetics and genuine technical fabric — their Good Karma leggings have a slight flare that photographs beautifully but still has enough compression through the thigh that I've worn them for actual 5Ks, not just coffee runs.

Hottest vs. Most Popular: Why These Are Two Different Questions

I make this distinction constantly because readers conflate the two and end up disappointed — a brand can be everywhere on your For You page this week and still have shipped fewer units last quarter than a legacy brand nobody's talking about at brunch. Bandit Running is genuinely hot right now, having grown from a scrappy Brooklyn running club into a brand stocked in over 200 stores, but its total volume still doesn't touch Nike's.

Lululemon remains the most popular by almost every traditional retail metric — foot traffic, repeat purchase rate, total revenue — even though its growth rate has slowed compared to upstarts like Vuori and Alo. I still buy their Align leggings every year specifically because the fit is so consistent across sizes that I don't need to try them on anymore. Is its own kind of trust that newer brands haven't earned yet.

Nike's most popular activewear lines, particularly the Dri-FIT training tops, sell in volumes that dwarf almost every brand on this list combined, according to their own quarterly reporting — popularity at that scale is a different game entirely, built on four decades of brand equity rather than a single viral drop.

What Is the Best Activewear Brand? My Honest, Tested Answer

I get asked this question more than any other, usually by someone standing in a fitting room texting me a photo. My answer has stayed consistent for three years: buy for your actual workout, not for the brand's Instagram aesthetic. I've watched too many friends spend $98 on Alo leggings for a spin class when a $58 Old Navy pair would have performed identically for that specific movement pattern.

My personal rotation, after six years of testing, breaks down by activity — Vuori for anything involving travel or errands because the fabric doesn't wrinkle in a suitcase, Gymshark for barbell work because the seams sit away from friction points. Alo specifically for hot studio classes because their compression doesn't loosen with sweat the way three other brands I tested did within 20 minutes.

If I had to pick one brand for a reader who only wants to own one, it would be Vuori, purely on the data — 100+ retail locations, a reported valuation in the billions. Personally, zero garment failures across 40-plus wears logged in my testing spreadsheet since 2022.
