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 prints are stealthy, until you don't want it to be. The mushroom pattern is a mellow gray/black, and then when the light hits it just right, the print comes to life and looks like it's from another dimension.

Short Features:

  • Built in black Compression underwear
  • Zippered tech storage pockets
  • Embroidered Peach icon on left leg
  • Elasticated waistband with drawstrings (extra stretch for maximum comfort)
  • Reduced length — let's celebrate those quads!
  • Rainbow Reflective MUSHROOM printed outer fabric
  • With slightly wider waist to avoid "muffin top".



WAIST 26-29" 29-31" 31-33" 33-35" 35-38"


SIZING: Runs big. Order a size down if you're in between sizes. With slightly wider waist to avoid "muffin top".

I waited 3 months for my two pair after two months I decided to email them. They stated they had problems getting in material and in this current market I’m not surprised. Once they got to me holy sh**! These things are incredible. So if you have a order you’ve been waiting on just keep waiting it so worth it.

They look great, and for these to be my first pair of compression-lined shorts, I'm not disappointed a bit! I'll definitely be ordering more!

Very nice but fits like a small, not an extra small

I was really excited to buy these because every few companies actually offer extra small! Unfortunately though these fit just a tad tighter than a regular old small you would find at a big box store. They still look great and I love the quality, but I'll have to wear a looser fit t-shirt to match.

Love these shorts! The reflective mushroom pattern is super cool. I’ve never done shorts with a liner, would probably do without next time, but I think I like them.
