Our verdict

A long-sleeve compression rash guard with a silicone waistband and a loop that anchors it to your shorts, plus flatlock stitching and a bonded neckline. It suits trainees who grapple often and want a top that stays tucked in.

Hayabusa's UK store describes the Apex Core long-sleeve rash guard as best for jiu-jitsu and MMA. It is made from a 200GSM (grams per square metre) four-way stretch polyester/elastane blend with a second-skin fit, and Hayabusa tags it as compression wear. The store lists reinforced flatlock stitching, a bonded-seam neckline, a silicone-lined anti-slip waistband and a lockdown loop on the hem that anchors the top to your shorts.

Hayabusa does not publish the exact fibre percentages, and an Amazon listing for the same top gives 100% polyester instead.

Best suited to

Intermediate and experienced trainees who grapple often and want a top that stays tucked in through scrambles.

Research-based editorial ratings — not customer reviews.

Pros

  • Two features to keep it tucked in: a silicone waistband and a lockdown loop that anchors to your shorts
  • Reinforced flatlock stitching and a bonded neckline, per Hayabusa
  • Sizes S to 3XL from Hayabusa's own UK store

Cons

  • Exact fabric percentages are not published, and retail listings disagree on the blend

Why we rated it this way

Comfort (4): Hayabusa lists a silicone waistband and a lockdown loop that anchors to your shorts, two features to keep the top tucked in, plus a bonded neckline.

Materials & Construction (3): Hayabusa states a 200GSM four-way stretch polyester-elastane fabric with flatlock stitching, the normal build for a rash guard. The bonded neckline is a step above that.

Value (3): A premium price for a 200GSM four-way stretch top with a silicone waistband and a bonded neckline, which matches what rash guards at this price normally offer.

Sources

  • Manufacturer — Hayabusa's own UK product page - 200GSM polyester/elastane blend, second-skin fit with the product tagged as compression wear, flatlock stitching, bonded neckline, silicone-lined waistband, lockdown loop, sizes S-3XL, and the GBP purchase route.
  • Manufacturer — Hayabusa's US product page for the same model - the same specification.
  • Other source — Amazon UK listing for the same model, sold by Hayabusa Fight EU - it lists 100% polyester, which conflicts with Hayabusa's own description. Recorded as a contradiction only, not as a purchase link.
