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:

  • Zippered tech storage pockets
  • Embroidered Peach icon on left leg
  • Elasticated waistband with drawstrings (extra stretch for maximum comfort)
  • 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 MUSHROOM printed outer fabric
  • With slightly wider waist to avoid "muffin top".


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: Runs big. Size down if needing true to size. With slightly wider waist to avoid "muffin top".

This version of our liner active shorts is slightly longer in length compared to the original release. (5 inch inseam with compression underwear extending 1.5 inches longer than the outer short). Slightly wider waist to avoid "muffin top".

Comfy and Durable

Definitely surprised by the weight and material of the product. A lot heftier and more durable than I thought it would. The only gripe I have is that it is a bit loose, so I need to make sure that it is tied tight enough to stay on when I work out. Other than that, great product!

Love the shorts BUT…

I love these shorts, but it took me three times to get the right fit. I initially ordered a size medium (what I normally wear) but they were too loose. I exchanged for a small- still a bit loose. Finally, I decided to give the XS a shot and they fit perfectly! By the way, I like to wear my shorts fitted.

They are great workout and party shorts, every time someone takes a picture with the flash it's a hit.

gorgeous shorts, beware runs large!

perfect flash properties, not too aggressive. it's visible in range of light conditions. gentle shimmer in full light at the gym, flashy at the club. appears matte on a cloudy day outside. material is thick n durable but still stretchy and soft and comfy. only had these a few weeks, so not sure how durable the ink/flash effect will be but they are sooo cute. i got a medium as usual (32.5" waist) but they are honestly designed like a large. i usually wear things somewhat fitted but this was more than a lil loose. the site did warn "runs large" but it ended up fitting like it was a full size bigger, despite ordering the right size for my waist...just kinda confusing sizing. my legs are kinda thicc and these made em look scrawny af lol. but they're a beautiful pair of shorts to grow my ass into!!!
