The best waterproofing for any garment or leather is anything that is not a SPRAY!
Sprays are mineral or chemical based and only apply a VERY thin coat to your garment. This quickly wears off and can damage the fabric.
Wax based waterproofing products permeate deeply into the fabric creating a lasting waterproof protection. However, beware of waxes than are flammable because of the use of chemical dryers such as linseed oil or turpentine. Use the good stuff and you will have a waterproofed product that will last for years.
Back in the day, all outdoors folk and the
military relied on a simple yet effective way to
waterproof and preserve their
canvas and cotton outer garments. Using an
old Civil War formula Ole Time Woodsman has recreated an
original, all natural formula that when applied
properly will guarantee that your garment or
hat will be waterproof AND stay that way with
some annual touch ups.
How to apply your Oilskin Wax:

pan of water on stove

brush. Warm with hair dryer and let stand for
24-48 hrs. Several coats may be necessary to
reach your desired waterproofing.
