BeHOT ™ with ROICA ™ for Modern Action Living

SITIP are pleased to introduce BEHOT™, a SITIP Heat Generating Technology for fabrics that has been licensed from the unique ROICA™ Stretch Energy® System by Asahi Kasei.
BeHOT™ represents a special combination of a highly refined type of knitted construction combined with this unique ROICA™ Premium Stretch yarn function, and has been especially developed for this new high-function concept.
BEHOT ™ is the unique fabric able to generate and retain heat when stretches!
Thanks to this special patented system, the fabric action of stretch and recovery is able to produce “at least a 1 degree temperature” increase that is then stored to support the wearer both during and post exercise!


  • BeHOT ™ is a true thermo-regulating fabric system
  • BeHOT™ is generating at least a one-degree temperature increase because of the physical process of elongation, so reducing entropy.
  • BeHOT™ Heat Generation technology reduces heat loss and maintains a constant body temperature during and after exercise.
  • BeHOT™ heat generation varies according to the type of materials used, but in every blend and mix, the fabric always minimizes heat loss while storing energy warmth during exercise without loss.
  • BeHOT™ fabric system is perfect for many applications such as active wear, outdoor/climbing wear, shapewear/innerwear, hosiery and cycling.

And in verified tests, SITIP & Asahi Kasei have been able to prove the real power of the BeHOT™ heat generating fabric ranges by calibrating them in laboratory tests that consist: 1 – Placing BeHOT™ fabric on the left of a dynamometer and a regular fabric on the right, and then observing the respective temperatures on a thermograph after repeated fabric elongations to 50%. 2 – At the end of the test, only the BeHOT™ technology fabric showed a substantial difference on the thermograph, And indeed, during the phase of repeated elongation for one minute, only the BeHOT™ fabric showed temperature increases, proving the fabric’s potential for generating and maintaining warmth. Another positive aspect showed the thermal effect persisting during and after exercising. This unmistakable feature makes BeHOT™ one of SITIP’s most remarkable and popular high function fabrics.

BeHOT™ range of fabris consists in the following items both for base and second layer garments:

  • BLIZZARD BeHOT™- first & second layer fabric for plain solid bike winter pants, climbing, running.
  • BLIZZARD PLX BeHOT™- first & second layer fabric in white for sublimation for running & bike winter pants, climbing & mountaineering.
  • Instinct PLX BeHOT™ GZ– base layer for technical underwear, fitness, warm ups.
