FYT Jeans


The unique side of engineering and technology used to deliver comfort and performance.

The Methodology

Data collection

We examined the comfort and fit of this innovative design in 20 subjects. The participants were limited to people that work in the seated position and regularly wear jeans. Variables related to compression forces, temperature and pressure were analyzed, using appropriate sensors. Compression forces were measured with six sensors physically connected to a device, which then transmitted recorded data via Bluetooth to a tablet. The same device supported one temperature sensor (NTC thermistor). Pressure was measured using a Tekscan’s ConformatTM #5330, composed by 1024 piezoresistive sensors. The compression sensors and the temperature sensor were placed with adhesive tape in the interior of the jeans on several body locations.

Tests were performed for all 20 participants at the beginning of the day, to ensure that they all would be able to wear the FYT Jeans for a whole working day (~ an 8 hours period). Each measurement was conducted for 15 minutes, for a total of 45 minutes. During these 15-minute measurements the participants were asked to perform their usual tasks, sitting at a desk, in front of their computers. The first measurements were conducted with participants wearing their personal jeans, while the second set of measurements were conducted with participants wearing the FYT Jeans provided for this study.

At the end of the day, each participant had to return the jeans and complete a short Likert-type scale questionnaire designed to evaluate participants’ perception of comfort and work performance. Different gradations of comfort and performance were included, including overall perception of physical and thermal comfort, performance at work, range of motion allowed, and the impact of these jeans on self-image.

Data analysis

Pressure and temperature variation were recorded for each sensor. The mean and variation between measurements was calculated. These comparisons were analyzed in terms of decrease of compression in the various body locations.

Data from the pressure-sensing mat were analyzed with Tekscan’s software and with a custom-made LabView application.


The Results

Users perception of comfort was immediate, especially when the invisible zipper in the buttock is open, allowing the growth of the crotch length. The comfort in the knee area and the pressure release in the waist were also referred as having influence in their sense of comfort. These answers confirmed the registered values by the sensors, having recorded compression forces reductions up to 77% for the backside of the knee and 65% for the front side; up to 90% reduction in the waist; up to 55% lower compression in the crotch sensor and 50% in the sacral area.


For whom?

A day time designer who’s a night time runner.
A snowboarder that drives two days straight to catch the perfect powder.
An entrepreneur that catches plane after plane to sell his business idea.
A day time food critic who’s a night time professional dancer.

Each of us has moments of motion and prolonged periods of rest in our daily routines, and FYT Jeans suits both of these moments, with comfort and style.
