The swim brief is a decades-old icon of masculinity, athleticism, and male sexuality. But, in my experience, finding one that fits has been a challenge. 

On more traditional swim briefs, the front pouch is often too flattening/unflattering to the male anatomy; on the other hand, briefs with a more modern design tend to over-correct this problem, and the result creates something that is too "out-there" for my comfort.

I designed our swim-brief to find the sweet spot between these two experiences:

The front pouch, with its 2 layers of lining and pocket for our optional soft cup insert (recommended), is contoured precisely to give your package that ideal round, full look without showing too much detail.

In the spirit of the classic swim briefs of the past, we kept the rest pretty simple:

  • 4 solid colors to choose from (with a very subtle shine). 
  • A drawchord that ties on the inside.
  • Our small, black "GA" logo on the front right hip.

Our Swim Brief is MADE IN THE USA

I recommend purchasing this suit with our soft cup insert (add for an additional $4.00 US), as it helps give your package a fuller, rounder look, and reduces excessive detailing of your anatomy. Before purchasing, look through the photos I have included to see how the soft cup insert fits into the liner pocket, and to see how the suit looks with and without the soft cup insert.

Side Seam / Hip Height at most narrow: 2 3/8” (for size medium)

Colors: Charcoal, Blue, Red, Purple


  • Lining: 2 layers of soft, Radiance nylon/spandex fabric in the front pouch only.

    • bottom of lining attaches to crotch seam; top of lining attaches to to top of waist band; the sides of the lining have elastic in them and do not attach to the body of the swimsuit. This is to help give your pouch that more full, round look. :)

    • Lining Pocket: The inside layer of the lining has an opening at the top to insert our optional molded soft cup (recommended) to give your pouch an even slightly fuller look without being too over-the-top ;)
  • Center back elastic: 1/4” width elastic sewn into center back seam to give definition and a subtle lift to your butt without any fabric ruching.

  • Drawcord: Charcoal gray; round; 3/8” thick; Does not stretch; Finished with metal end cap; ties on inside front.

  • Logo: Small, black “GA” heat-seal logo on front right hip.


  • Body Fabric: We used a luxurious, heavy-weight ,Nylon / Spandex fabric for this style only. Our Power Jersey fabric has a beautiful, smooth hand feel, and a subtle shine. Compared with the fabric we used for our other tighter swim styles, this fabric stretches slightly less. But I thought it gave the brief a classic, smooth, luxurious look.

  • Lining Fabric: ultra-soft, 4-way stretch Radiance nylon/spandex

Please Note:

The key feature that makes this swimsuit unique is the lining (see photos). The lining is attached to the body of the suit at the top and the bottom, but not at the sides, as most other brands have it. I found that this design helps best create that round, full look I’ve always sought after. So PLEASE NOTE: getting into this suit does require more adjusting than you may be used to, and it will be a snug fit for guys of average endowment, but the good news is that once you get everything all in place, it should stay there, and it will look great!


**None of the photos of the swimwear on this site were edited to alter the colors of the swimsuits, or to smooth out any wrinkles or fold lines of the swimsuits, etc. I asked the photographer to make sure of this so that you guys can have an accurate idea of what this swimwear looks like when worn**

CARE LABEL INSTRUCTIONS: Machine wash cold with like colors. Hang to dry. Do not iron. Do not bleach.


Front Pouch: fits very snug for the 'average' guy. It will take a minute of adjusting to get all your 'stuff' inside. Personally, I think it's worth the effort, because I like the look of a pouch I can fill entirely. 

Seat: FULL seat coverage. 
PLEASE NOTE: This suit is designed to fit best on guys with larger, fuller butts. If you have an average, or smaller butt, the mini brief will probably fit you better in this department.


*please note: this style is intended to fit snug. If you do not want such a tight fit, order a size up*

Love the purple swim brief

I bought a size large. The color is amazing. The leg holes are a little snug but I think will stretch a little with wear.

Excellent products

Love love love Grand AXIS

Swim brief

Love the cut and material...the pouch is a bit small and crushes my junk, but other than that, love it

I will come back for sure!

So glad I decided to buy these. The fit is really something else and the material is very comfortable. My butt just plumped by wearing these and I love it! The seam between the cheeks feels nice and make your ass looks bigger! I will definetely shop again for the next swimwear opening.

Excellent products!

They fit perfectly as announced with one size up.
