• Comfort:


The comfort certification issued by AITEX is based on the objective evaluation of the comfort provided by an article depending on its type and the use for which it has been designed.  The certificate is applicable to any type of textile, from duvets to sportswear and children’s clothing.


Most frequent laboratory tests performed by the Institute:

-Thermal resistance (Rct) and water vapour resistance of textiles (Ret)

-Water vapour transmission of laminated fabrics

-Thermal insulation of sleeping bags- temperature range

-Thermal insulation capacity of adult and children’s clothing (thermal manikin)

-Resistance to rainwater penetration using a rain tower

-Resistance to wind penetration (wind tunnel)

-Thermal insulation of gloves (thermal hand)

-Breathability of gloves

-Thermal insulation of footwear

-Breathability of footwear

-Thermographic analysis

-User comfort analysis


Most important comfort equipments:


The thermal manikin allows the thermal insulation and breathability properties of clothing and sleeping bags to be measured, in order to establish the comfortable working temperature at which the tested article may be used.

We have an adult (man and woman) and a children sweating manikin.



The equipment measures the thermal insulation and breathability performance of gloves to establish at what temperature the wearer will be comfortable.



The equipment measures the thermal insulation and breathability performance of footwear.



The Institute’s high-performance wind tunnel allows us to measure and evaluate the thermal sensations experienced by a person dressed in the test article at wind speeds of up to 10 m/s.

The tunnel is used to test and study new garments designed for extreme environments in a range of conditions:

  • Temperatures between -30ºC to 60ºC.
  • Humidity to 90%
  • Wind speeds up to 40 Km/h.



The rain tower simulates falling rain and its effect on a garment designed for foul weather. The equipment measures the waterproof performance of a garment under static conditions.

  • Sports laboratory:

Gas analysis

The equipment analyses the volume of air breathed in and exhaled and concentrations of O2 and CO2 to determine the quantity of oxygen used by the body during exercise and at rest, to establish the athletic performance of the subject.

Electromyography used to evaluate muscle function

The equipment allows the Institute to analyse the muscles used in a range of movements and postures to determine which muscles are active at any one time.

Electronic goniometry

Measures the angles formed by a joint to measure the degree of movement available or lack of movement.

Force platform

A force platform is used to study ergonomics and is used to monitor and analyse the movements and forces involved during sports and in the training regimes of athletes.

Kinetic analysis of walking

Kinetic analysis of walking is performed using sensorised insoles to create a map of the different pressures exerted by the foot at rest and during walking to analyse each foot separately.

The test measures the stability of the step and impact absorption during walking, which are both vital parameters to ensure comfort and athletic performance.
