Yet the global activewear market hit $406.1 billion in 2024 and is projected to reach $771.8 billion by 2034 (Precedence Research, 2024), and most comparison content reads like marketing copy. This guide is different. We're FIERCEPULSE, and we'll tell you where Buffbunny beats us. We'll also tell you where we win. By the end, you'll know which brand fits your body, budget, and style, no hype required. For broader context, see the complete printed leggings guide.

How Do FIERCEPULSE and Buffbunny Compare at a Glance?
Buffbunny launched in 2017 and FIERCEPULSE in 2018, putting both brands at roughly eight years of trading by 2026 (Crunchbase, 2024). The two operate on opposite supply models: FIERCEPULSE prints on demand, Buffbunny pre-produces seasonal collections. That single difference cascades into everything below.
| Feature | FIERCEPULSE | Buffbunny |
|---|---|---|
| Founded | 2018 | 2017 |
| HQ | Boynton Beach, FL | Houston, TX |
| Business model | Print-on-demand (made-to-order) | Pre-produced seasonal drops |
| Print catalog size | 900+ unique prints | ~20-50 patterned SKUs per season |
| Sizing range | XS-6XL | XXS-XL (select styles XXL) |
| Price range | ~$80-$110 | ~$60-$90 |
| Print method | Dye-sublimation, polyester-spandex | Solid dye and printed panels, nylon-spandex blends |
| Signature feature | 900+ print catalog, no sellouts | Miracle Seamless, scrunch-back fit |
Citation capsule: FIERCEPULSE, founded 2018 in Boynton Beach FL, runs a print-on-demand model with 900+ unique prints and XS-6XL sizing. Buffbunny, founded 2017 in Houston TX by Heidi Somers, runs pre-produced seasonal drops with a signature scrunch-back fit and XXS-XL sizing (Crunchbase, 2024).
Which Brand Has Better Print Variety?
FIERCEPULSE wins on raw variety. Our catalog carries 900+ unique prints available year-round, none of which sell out, because each pair is printed when you order. Buffbunny releases curated seasonal collections, typically 20-50 patterned styles per drop, with a hype-driven scarcity model that frequently sells out within hours (Shopify Plus case studies, 2023).
FIERCEPULSE: Always-On Catalog
Our internal catalog audit (May 2026) counts over 900 active print SKUs, with roughly 40 new designs added monthly. Dye-sublimation lets us print full-coverage patterns, including all-over galaxy, animal, floral, and geometric designs, without color-bleed at seams.
Buffbunny: Seasonal Drop Culture
Buffbunny's strength is curation. Heidi Somers built the brand around themed collections (Reborn, Limitless, Radiant), and her ~500K Instagram followers treat launches as events (Buffbunny Instagram, 2024). The aesthetic skews bold-but-controlled: solid jewel tones, marble prints, and scrunch-friendly fabric panels.
Verdict: FIERCEPULSE wins on variety and availability. Buffbunny wins on trend-forward seasonal cohesion.
How Does the Fit Compare?
Buffbunny wins on signature fit. The Miracle Seamless and scrunch-back constructions are widely credited as the brand's standout feature in YouTube creator reviews (Buffbunny Collection product pages, 2024). FIERCEPULSE competes on standard high-rise comfort but doesn't replicate the contoured scrunch silhouette.
FIERCEPULSE Construction
Our standard build is a high-rise (10.5-11 inch) waistband in a polyester-spandex blend, designed for full-coverage pattern integrity. Squat-tested, four-way stretch, flat-lock seams. The trade-off: dye-sublimation requires polyester, so we don't compete in the nylon-feel category.
Buffbunny Construction
Buffbunny's Miracle Seamless series uses circular-knit construction, giving the smooth, second-skin feel that drives most of the brand's social-media buzz. The scrunch-back uses ruched paneling for a contoured rear silhouette (Buffbunny Collection, 2024).
We've tried both. If you specifically want a scrunch-back lift effect, Buffbunny is the better buy. If you want a bold print with a clean high-rise silhouette, our build is competitive.
Verdict: Buffbunny wins on signature fit. FIERCEPULSE holds its own on standard high-rise comfort.
Which Brand Has Better Sizing Inclusivity?
FIERCEPULSE wins decisively. We carry XS through 6XL across the full catalog, every print, every cut. Buffbunny's standard run is XXS to XL, with select styles offered in XXL (Buffbunny Collection size charts, 2024). That's a meaningful gap when 67% of U.S. women wear size 14 or above (Plunkett Research, 2023).
The print-on-demand model is what makes our extended sizing economical. Pre-produced brands have to forecast demand across every size in every print, then accept dead inventory in the sizes that don't sell. We cut and print only what's ordered, so a 6XL galaxy legging costs us no more risk than a small.
Verdict: FIERCEPULSE wins clearly for plus and extended sizing. For the Buffbunny alternatives with similar inclusivity, see our sibling guide.
Is Buffbunny Cheaper Than FIERCEPULSE?
Yes. Buffbunny prices most leggings between $60 and $90, while FIERCEPULSE sits at $80 to $110 per pair (Buffbunny Collection, 2024). The price gap reflects different cost structures: bulk pre-production lowers Buffbunny's per-unit cost, while our made-to-order printing costs more per pair but eliminates waste.
What You're Paying For
- Buffbunny premium: signature scrunch construction, brand cachet, in-stock shipping
- FIERCEPULSE premium: unique print exclusivity, extended sizing, zero-waste production
Verdict: Buffbunny wins on sticker price. FIERCEPULSE wins on dollar-per-unique-print and dollar-per-extended-size.
How Do Shipping and Availability Compare?
Buffbunny ships faster on average. In-stock orders typically leave the warehouse in 2-5 business days. FIERCEPULSE prints to order, which adds 5-10 business days of production before shipping (FIERCEPULSE shipping policy, 2024). The trade-off is honest: speed versus deadstock waste.
Buffbunny's drop model creates a different speed problem: popular sizes sell out, sometimes within hours, then restocks take weeks or never happen. FIERCEPULSE never sells out because we never pre-produce.
Verdict: Buffbunny wins for in-stock turnaround. FIERCEPULSE wins for guaranteed availability across the catalog.
Which Brand Is More Sustainable?
FIERCEPULSE has the structural sustainability advantage on waste. Our made-to-order model produces zero fabric overrun, addressing the 92 million tons of textile waste generated globally each year (Ellen MacArthur Foundation, 2024). Buffbunny has not published detailed sustainability disclosures as of May 2026, so direct comparison on lifecycle metrics isn't possible.
Both brands use synthetic fabrics derived from petroleum. The honest framing: structural model favors FIERCEPULSE on waste, but neither brand uses recycled or natural-fiber base materials at scale.
Verdict: FIERCEPULSE wins on waste structure. Neither brand wins on fiber sourcing.
What About Customer Reviews and Brand Reputation?
Both brands are legitimate, established, and well-reviewed within their lanes. FIERCEPULSE has served 88,000+ customers as of 2026 and maintains a 4.6/5 aggregate Shopify rating (FIERCEPULSE on Knoji, 2024). Buffbunny carries a ~500K Instagram following and broad YouTube creator coverage (Buffbunny Instagram, 2024).
The two reputations differ in shape. FIERCEPULSE is review-driven and product-led. Buffbunny is influencer-driven and personality-led (Heidi Somers herself is a major draw).
Verdict: Tie. Different reputation engines, both legitimate.
Who Should Pick Which Brand?
Pick FIERCEPULSE if you:
- Want a print no one else in the gym owns
- Wear XL, 2XL, 3XL, 4XL, 5XL, or 6XL
- Prefer zero-waste production over fastest shipping
- Value catalog stability (no sellouts)
Pick Buffbunny if you:
- Want the signature scrunch-back contour
- Wear XXS to XL and fit Buffbunny's body block
- Prefer in-stock shipping speed
- Buy into the seasonal-drop excitement and Heidi Somers brand
What If Neither Brand Is Right for You?

Frequently Asked Questions
Is Buffbunny better quality than FIERCEPULSE?
Neither is universally "better." Buffbunny's seamless and scrunch-back construction is widely praised in creator reviews (Buffbunny Collection, 2024). FIERCEPULSE's dye-sublimation prints are full-coverage and fade-resistant across 88,000+ customer orders. Quality verdict depends on whether you value fit signature or print fidelity more.
Does FIERCEPULSE run smaller or larger than Buffbunny?
FIERCEPULSE runs true to U.S. women's standard sizing across XS-6XL. Buffbunny's body block is widely reported by creators to run small, especially in scrunch and seamless styles, with many reviewers sizing up one (Buffbunny Collection size guide, 2024). Check both size charts before ordering.
Why is Buffbunny cheaper than FIERCEPULSE?
Buffbunny pre-produces inventory in bulk, lowering per-unit cost. FIERCEPULSE prints each pair on demand using dye-sublimation, which costs more per unit but eliminates overproduction waste (Ellen MacArthur Foundation, 2024). You're paying for either bulk efficiency or zero-waste customization.
