This winter will be the third season for the “synthetic downâ€, known as Thermoball, created by Primaloft in collaboration with The North Face and the latest creations are divided into two ranges.
Thermoball Pro
Thermoball Pro is top of the range and boasts a new bottleneck quilting design that no longer divides the insulation into squares, resulting in the elimination of cold spots. As you can see in the photo above, the design consists of parallel ondulating stitching that doesn't cross at any point.This new system provides a notable increase of the warmth to weight ratio in comparison to the original Thermoball design. Other features have also been improved, such as the finishing, lining fabric and overall design.
Thermoball Sport
The original design of the Thermoball has been renamed as “Thermoball Sportâ€. This has the original quilting pattern and is designed for casual use in less extreme conditions. Although the Thermoball Pro offers higher performance, the Thermoball Sport is more than sufficient for most situations and at a more affordable price.
