IN STOCK! Available for IMMEDIATE Shipment.

Dichroic "squid ink" fabric inspired by 500+ million years of evolution.

The squids' skin is one of the most complex and unique biological materials on this planet. While most creatures with color-changing ability do it to hide, squids do it to attract. Which is where the inspiration for flexliving's reflective release came from.

Our rainbow reflective fabric is stealthy, until you don't want it to be. The fabric is a mellow gray/black, and then when the light hits it just right, it comes to life and looks like it's from another dimension.

Swim Trunk Features:

  • Stretch mesh liner for maximum comfort
  • Deep mesh-lined storage pockets (plenty of room for your phone)
  • Embroidered PINK Peach icon on back pocket.
  • Elasticated waistband with PINK drawstrings (plenty of stretch)
  • Reduced length "just enough" (5" inseam which is slightly longer than our original 2.0 short, but still enough to celebrate those quads!)
  • Rainbow Reflective outer fabric


WAIST 26-29" 29-31" 31-33" 33-35" 35-38"
INSEAM 4.75" 4.9" 5" 5.15" 5.25"
LENGTH 14" 14.4" 14.75" 15.12" 15.5"


SIZING: Fits true to size.

Slightly wider waist to avoid "muffin top". If your quads are larger than average you might want to size up due to the lack of stretch in the reflective outer fabric.

Reflective Swim Trunks

The trunks look and feel very comfortable. They're not as baggy as typical men's board shorts. I will replace the pink drawstring with another color.

Best trunks EVER

I absolutely LOVE all of the shorts I've purchased so far. The colors are great, they're super comfortable, and they "rep the peach" perfectly. I'm so glad I invested in quality attire for gym, swim, and lounge.
