Mono B

Mono B is a Los-Angeles-based activewear and athleisure wholesaler that sells leggings, sports bras, bike shorts, joggers, tops and matching lounge sets priced mostly between $12–$28 wholesale ($24–$56 retail). The company operates a B2B portal at mymonob.com and an Amazon storefront; products reach consumers through 3,000+ boutique accounts across the U.S. and via Mono B’s own direct-to-consumer site, placing the brand in the budget-to-mid-range tier. The brand’s standout offer is “Mono B Platinum,” a sub-line of 36-piece minimum, quick-ship packs that land in stores within 3–5 days of order. All styles are designed in downtown L.A. and produced in vertically owned factories, allowing weekly drops of 60–80 new SKUs and inclusive sizing from XS to 3X/4X in most core leggings. Buyers are independent boutique owners and value-driven consumers who want trend-forward athleisure at entry-level price points; end-users are 18-35-year-old women who follow Instagram fitness influencers and favor “gym-to-street” outfits that can be restyled weekly without premium-brand mark-ups. Mono B competes in the fast-fashion activewear space against low-minimum, quick-turn wholesalers; it differentiates by keeping domestic design and production under one roof, guaranteeing 5-day ship times on pack orders, and publishing wholesale prices transparently online—tactics that let small retailers rotate inventory as rapidly as larger fast-fashion chains.
