HELLY TECH®

WATERPROOF. BREATHABLE. GUARANTEED.

Helly Tech® is the waterproof and breathable outer layer between you and the elements. Its unique membrane
stops water molecules going in, but lets moisture molecules escape. Keeping you dry from the outside and
comfortable on the inside.

DWR TREATED
WATER REPELLENT Helly Tech® is constructed with Polymer Polyurethane (PU ) based membranes and
coating technologies. The PU membrane gives softness and stretch to the fabric, while the
coating allows waterproofness and breathable qualities. Helly Tech® is made either with
Hydrophilic barrier membranes or Micro-porous membranes, depending on the end-use
OUTER FABRIC
purpose of the fabric.

WATERPROOF AND The Hydrophilic barrier works on an osmotic principle, keeping salts from entering and
blocking the pores. The Micro-porous PU membranes are hydrophobic- “water hating”
BREATHABLE
polymers. This membrane construction is responsible for the waterproofness of Helly
MEMBRANE Tech®, making the pores up to 20.000 times smaller than water droplets, while allowing
breathability since the pores are up to 700 times larger than a water vapor molecule,
allowing the evaporation of sweat and heat.

Helly Tech® is actually more than just a fabric – it is a combination of a DWR-treated outer
fabric, a highly breathable and waterproof membrane, fully sealed seams and often a highly
breathable inner fabric, mesh or lining.
FOR MAXIMUM The seams of the products are taped over with a waterproof ribbon and glue, preventing any
WATERPROOFNESS
water from entering the small gaps between the stitches of the seams.
