What kind of material is 'ABS' mentioned in the ball cap description?
It is an English abbreviation that suddenly appears in the description of the brim, making it difficult to understand what it refers to. Since they say this cap does not use that material, it makes one wonder what is different.

ABS is a hard plastic commonly used for cap brim stiffeners, and this cap instead used compressed wool to make the brim.
ABS is a plastic made by combining three components: acrylonitrile, butadiene, and styrene. It is lightweight, hard, and maintains its shape well, so it is widely used for items whose shape must not be distorted, such as home appliance exteriors and toys, and in hats, it acts as an interfacing stiffener inserted inside the brim. However, precisely because it is rigid, if it is folded or pressed significantly, marks may remain at the fold line, or it may break.
RYOO did not use ABS in this cap's brim, but inserted a compressed wool material so that the brim moves flexibly[1]. Compressed wool material is formed by fibers intertwining and hardening, so it has a certain degree of elasticity, and possesses the property of trying to return toward its original shape when bent and released.
hmmm, listing the name of a material that many brands use seems to read as an explanation intended to say what this brim is not made of before saying what it is made of.
The thickness of the compressed wool brim, as well as washing and storage instructions, have not yet been confirmed.
