A 2 layer garment is made from 2 layer Gore-Tex. The Gore-Tex has only the face fabric laminated on the outside. To protect the Gore-Tex on the inside when made up as a garment, a loose lining is added, usually a mesh lining for extra breathability.
Gore-Tex fabrics are waterproof and will not let water in even where there is pressure from rucsac straps etc. So the issue is how long the garments will be waterproof.
Gore-tex is extremely durable waterproof and many consumers have jackets over 20 years old that still perform well.
Aquafoil is durable and most consumers will get many years usage from their jackets.
