Our verdict
The most fully specified rash guard in this category, at the highest price here. It has a silicone waistband, a loop that anchors it to your shorts, flatlock stitching and a bonded neckline.
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 confirms 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. An Amazon listing for the same top says 100% polyester, which conflicts with Hayabusa's description. It is not sold as a ranked (belt-colour) range.
Intermediate and experienced trainees who grapple often and want a top that stays tucked in through scrambles.
You are on a budget (see the RDX T15). You need a ranked colour for IBJJF no-gi competition (see the Tatami ranked rash guard).
Pros
- Two confirmed retention features: 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
- The highest price in this category
- Exact fabric percentages are not published, and an Amazon listing contradicts the blend
- Not a ranked range
Why we rated it this way
Rated on Comfort, Durability and Value only - this is apparel, and a Protection star score would imply a protective function it does not have.
Comfort (4): the most confirmed fit and retention features in this category - a silicone waistband, a lockdown loop and a bonded neckline.
Durability (3): flatlock stitching and a 200GSM fabric are stated, but there is no independent durability evidence, so this is not rated higher.
Value (3): a premium price for the strongest retention specification.

- 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.
