coat
袍 centers on a long, loose outer garment: a coat or robe worn over other clothing.
袍 combines 衤 (clothing) with 包, which likely contributes the sound and the idea of wrapping or enveloping, suggesting a garment that wraps around the body.
The clothing radical 衤 beside 包 (wrap) suggests a garment that wraps around you: a coat.
For ホウ, imagine wrapping yourself in a warm coat and letting out a satisfied breath: 'hoe' (as in exhaling) -> ホウ.
