SHATNEZ

[Koberstein]

Shatnez, the biblical law that forbids wearing a garment containing a mixture of
linen and wool, is generally regarded as the quintessential example of a law for
which there is no rational explanation The Bible offers no reason for this ordinance.
It speaks of Shatnez first in Leviticus 19:19, in the verse following "Love your
neighbor as yourself," where the prohibition is stated vaguely: "You shall not put
on cloth from a mixture of two kinds of material." Deuteronomy 22:11 which
specifies "You shall not wear cloth combining wool and linen," is understood to
be an elaboration of the earlier verse.
Few non-Orthodox Jews are aware how punctilious their coreligionists are in
observing this biblical law. A company called Shatnez Laboratories, located
in Brooklyn, New York, checks woolen garments to make sure that no linen
has been mixed in. Large department stores that have an observant
Jewish clientele are well aware of this regulation.

From a common sense perspective (no explanation needed) it makes no sense to wear clothing made of two materials with each having its own special application.

One for utilitarian use (cold weather and repelling rain). Wedding gift.
HBC White Wool blanket - Hudson Bay trade good for 6 beaver pelts...

Fine White Linen for sacred ceremonial application.
One time use for special wedding dance celebration ...

Another unlikely comparison would be using both white pine and red cedar as 2x4 studs in house construction, Or a clay pot with gold handles, Or an ox yoke inlaid with precious stones.
