Helly Tech® is constructed with Polymer Polyurethane (PU) based membranes and coating technologies
The Helly Tech® Pro in this jacket is made with a micro-porous membrane
The PU membrane gives softness and stretch to the garment
The micro-porous PU membranes are hydrophobic - “water hating” polymers.
This membrane construction is responsible for the waterproofness of Helly 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 the pores.

LIFALOFT™ developed in cooperation with Primaloft®
Lifaloft™ is a combination of LIFA®’s unique insulation structure and Primaloft®’s extensive knowledge in synthetic insulation.
With increased warmth, lightweight insulation and superior moisture management properties
LIFALOFT™ technology is an insulation revolution that will keep you warmer with less weight and bulk compared to traditional polyester insulation
How LIFALOFT™ Works:
The unique hydrophobic properties of the Lifa® fibers deliver moisture management necessary for high endurance activities
The PrimaLoft® structure offers high insulation and breathable performance insulation for all active pursuits.
LIFALOFT™ insulation is based on LIFA® fiber technology that is engineered into a lightweight structure that traps more air than standard polyester, providing
extra warmth; the fiber does not absorb water, making the insulation technology ideal for intense activities in variable winter or summer conditions.
Recco® Technology makes you searchable for organized rescue in the event of an avalanche accident
The system requires no training and no batteries to function, meaning it is always “on” and ready.
RECCO® reflectors do not prevent avalanches nor do they guarantee location or survival in the event of a burial
