Tanthrough

Tanthrough sells swimwear, shirts, and cover-ups cut from a patented micro-mesh knit that lets up to 80 % of UV light pass through, creating a tan without removing the garment. Bikinis, one-pieces, board shorts, and polos sit in the mid-range bracket: most pieces run USD 40-90, with a handful of premium printed one-pieces topping out at ~120. Distribution is strictly e-commerce through the brand’s own site; no wholesale or pop-up retail is operated. The fabric itself—lightweight, quick-dry, and breathable—is the core IP; it is knitted with 200,000–300,000 pores per square inch, eliminating the need for sticky tanning lotions or topless sunbathing. Every style is offered in multiple skin-tone-matching prints that visually “disappear,” so tan lines are minimized. The brand’s best-known line is the “Enhancer” bikini collection, whose triangle tops include removable push-up pads that still transmit light. Customers are 18-45-year-old beachgoers and festival travelers who want an even tan without sacrificing coverage or SPF protection for tattooed or sensitive areas. They value efficiency (no strap adjustments while rotating), pack-light travel gear, and Instagram-friendly minimal tan lines. Tanthrough competes in the crowded mid-price swimwear and resort-wear space, but differentiates on function rather than fashion cycles: instead of chasing runway prints, it markets a utilitarian benefit—tan-optimized fabric—protected by long-standing patents. This positions the brand as a niche problem-solver beside mainstream labels that focus on aesthetics, sustainability claims, or compression performance.
