Seamless Cross-Back Sports Bra

Meet the Alpha Seamless Cross-Back Sports Bra – the 220 g “invisible” support layer that locks you in for yoga, spin or street sprints without wires, seams or sweat patches. Knit from 60 % sweat-wicking nylon / 6 % spring-back spandex in one smooth tube, this medium-support bra uses wide cross-back straps to distribute weight, free the shoulder blades and create a clean runway-ready silhouette. Eight trending colours, same-day dispatch from Yiwu.

• Seamless 360° Knit: zero side seams = zero chafe; four-way stretch rebounds after 50+ washes—no ripples, no rolls.
• Cross-Back Stability: fixed straps cross at mid-scapula to lift and centre—no sliding even during handstand push-ups.
• Wire-Free Medium Support: full-coverage mould cups + wide under-bust band give HIIT-level hold with zero poke or dig.
• Quick-Dry Performance: micro-yarn cross-section moves sweat outward; surface touch-dry in 10 min—no post-class chill.
• Soft Matte Finish: 60 % premium nylon feels like Lulu Nulu, blocks see-through and stays pill-free under barbells.
