The name of the product gives it away, the Teak collection is made out of a wood derivative called Modal. 'Modal' is made out of wood pulp, which is created by spinning the pulp into fibre which then gets turned into fabric. Modal feels twice as soft as cotton and can handle 3x the amount of washes than cotton.
The Teak fabric composition includes recyclable polyester, which adds a layer of performance characteristics to the garment. What we were specifically blown away with was the quick TTD (Time to Dry). We measured the TTD to be around <3 minutes, which is significantly faster than the 5-10 minute industry standard.
