KLIM GT1 EXPEDITION
The Klim GT1 Expedition
is a modular helmet
made from hand-laid full
carbon fiber, featuring
a proprietary chinbar,
hinge plate, and impact-
absorption materials
exclusive to Klim.
T
he Klim GT1 Expedition is a hand-laid, full
carbon-fiber modular helmet that incorpo-
rates a proprietary chinbar, hinge plate and
impact-absorption materials exclusive to Klim.
The design allows for easy and intuitive opening
of the chinbar. When closed, the chinbar is flush
with the shell to create a smooth, aerodynamic
seam-sealed closure, with no part of the chinbar
protruding. The GT1 comes with a clear shield, a
photochromic shield and a Pinlock—all of which
are easily installed without the need for tools and
are rated for Optical Class 1 clarity and HD vision,
even with the Pinlock anti-fog lens installed.
Ventilation is achieved via an adjustable top
vent and two ratcheting chin vents—one for direct
ventilation through the helmet and the other to
prevent fogging of the shield. All the forward-
facing vents are assisted by four low-pressure
exhaust vents on the back of the shell, which
pull air through the shell's unique Koroyd impact-
absorbent material. Koroyd is a honeycomb-like
material which, along with upper and lower EPS
foam layers, provides ECE 22.06 level protection
for both impact and rotational force absorption.
The helmet's removable interior liner is made of
perforated goat-leather suede and Brrr°, a trade
-
marked antimicrobial and moisture-wicking mate-
rial. The GT1 is offered in sizes XS through 3X
across three outer shell sizes for optimal weight
and aerodynamic performance.
