Thermo Grid HL fabric. Thermal efficiency with an excellent warmth to weight ratio.
Thermo Grid HL is a high loft grid back fleece fabric designed to maximise thermal efficiency with an excellent warmth to weight ratio. The fabric has a lightweight smooth fleece face and a brushed high loft grid back to trap air, reduce weight and improve packability. The double weave construction features 4-way stretch to provide unrestricted freedom of movement. The superior warmth to weight ratio means Thermo Grid HL is over 28% warmer than the standard Protium fleece fabric for the same fabric weight.
