Activewear Built to Move, Made to Your Brand

Fitness wear is tested every time someone squats, stretches or sprints. Customers notice straight away if leggings slip, seams rub or fabric turns see-through, and they don't come back.

Thiz International produces fitness wear to your specification for activewear brands, gyms and studios, personal trainers and retailers, with the fabric, fit and finishing details agreed before production.

Custom Leggings, Specified Detail by Detail

Leggings are the most requested item in most activewear ranges, and the details decide how they sell. These are the points we agree with you before sampling:

  • Length: full length, 7/8, capri, bike short or flared styles.
  • Pockets: waistband key pocket, side phone pockets or none.
  • Seams: flatlock, bonded or seamless knit, depending on the style.
  • Fabric: stretch blends, weights and finishes such as matte or brushed.
  • Branding: printed, reflective or heat-transfer logos on waistband or leg.

Build a Coordinated Activewear Collection

Many fitness brands launch with a capsule: tops, bras, leggings and shorts in the same fabric family and colourways. We produce the pieces together so colours and finishes match across the set.
