French gear brand IXON has just given us the coolest-looking technical undergarments – and the range is primed to get you powering through those high-heat track days this 2023.
Meet the IXON Underground – a sport-focused base layer designed not only to keep track revvers from overheating but to act as a compression aid for those who need extra support mid-yoink.
Per coverage from RideApart, the IXON Underground range sports three items – a full undersuit, a top jersey, and a bottom legging set, all of which have a Nylon + Spandex/Elastane blend in a seamless, moisture-wicking design, with additional compression points installed at the wrists, ribs, lower back, and ankles.
Endurance and performance are the IXON Underground’s operative, so the set has also been given a pull-zip at the chest and crotch for ease of removal, with the suit carrying a flat-lock assembly to make in and out a comfy breeze.
IXON has also been sure to include the following sizing:
- XS
- S
- M
- L
- XL
- 2XL
This particular adjustment is a relief, considering those same sizes used to be IXON’s “3, 4, 5, 6, 7, and 8” back around 2016.


Expect the full Underground undersuit to go for €119.99 EU ($132 USD), with the top and bottoms locking in at €59.99 EU ($66 USD) each.
