Size Guide

Harder, better, stronger, faster. We have the technology. We can make him better than he was. Work it, make it, do it.

BANG! Swim Briefs sport the cut of a classic men’s racing swimsuit, yet we tuned this bathing suit’s style up a notch by enhancing its curves to give it a trendier fit and BANG!’s signature ‘perfect fit’ in high-quality swimwear.

Fit sits low for a sexier masculine touch.

All BANG! Swim Briefs come equipped with our proprietary “Full Pack” system, providing a REMOVABLE padded frontal pouch that offers protection and a fuller feel in the right place, yet delivering a classy and tasteful masculine look in swimwear.

  • Exterior fabric: 83% Polyester and 17% four-way-stretch Spandex (Elastane - authentic LYCRA®) allows perfect contouring to the body and comfortable movement
  • Brief-shape liner inside made with superior-quality soft, light, and comfy material (88% Polyamide, 12% Spandex), fast drying, anti-bacterial treatment, odor protected
  • Chlorine/Salt/Sun-resistant: Colors remain bright and sharp longer, and will not fade when exposed to chlorine and saltwater; or upon washing and exposure to sunlight
  • Highest UV protection (UPF 50+)
  • Quick dry: high-performance fabric with moisture wicking
  • Sweat proof: Advanced technology that prevents fabric discoloration on contact with perspiration
  • Drawstring in waistband for best fit, featuring our signature branded metallic tips in gold.
  • Top-grade thread that offers both strength and durability, even in wet conditions 

Available sizes and measures:

• X-SMALL: 26”- 28” (66 cm – 72 cm)

• SMALL: 29”- 30” (73 cm – 76 cm)

• MEDIUM: 31”- 32” (77 cm – 82 cm)

• LARGE: 33"- 34” (83 cm – 88 cm)

• X-LARGE: 35"- 36” (89 cm – 92 cm)

• XX-LARGE: 37” - 38” (93 cm - 97 cm)

For swimwear in general, the rule is that measures are stated mostly by reference of regular-clothing waist size (not actual body measures). Using the example on this table, if you usually wear 33" in jeans or pants, then a Large should be your size of reference for BANG! swimsuits.


• Machine wash (cold) on delicate cycle, or hand wash. Lay flat to dry.

• Do not iron or dry in shade. Do not wring or scrub.

• Do not use chlorine-based whiteners. Do not use fabric softeners.

• Wash only with similar colors.

• Avoid contact with rough surfaces or sharp edges to prevent damage to the fabric.

    Excellent Customer Service

    The clothes are very trendy and fits well in the body. I wish they would have more options and varieties though. Customer service is something else. They are very attentive and go extra miles to assist you. The exchange size experience was outstanding. They sent me a pair of the size I needed as soon as I requested and before I returned the items that l had previously purchased. With no charge, no hassle, through a fast shipping. I really recommend them .

    Great brief

    Love how it fits. Sits low on the waste. The material feels soft and durable, overall well designed and fitted


    Exactly, Germán! The "secret weapon" of our Swim Briefs is that we cut them to sit low on the waist, so they deliver a sexier look when worn than "standard speedos." BANG! Swim Briefs are actually meant to be used like speedos but on steroids and now you are a witness to that! haha.. And yes, we make all our swim briefs with a premium fabric of the top grade in its category therefore its soft feel and the signature way it wraps against the body as per the way our patterns are designed. Remember that as with any other premium fabric it is also 'delicate.' Just be careful to avoid contact with rough surfaces or sharp edges to prevent damage to the fabric (stay away from sitting by the sides or stairs of a pool!), and you'll get the most out of your BANG! swimsuit in the long term. Thank you for your feedback, German, and keep enjoying your Bionic Stripes Swim Brief and wear it and flaunt it everywhere this summer!
