Are swim diapers really helpful? any recommendations?

A swim diaper is a diaper that is made for those who have incontinences and is to be worn underneath a bathing suit, or as a bathing suit. Swim diapers serve the purpose of containing fecal waste. Swim diapers can be reusable and disposable. They are not intended to be absorbent.[1] Typically, it is assumed that a swim diaper should be absorbent, or contain urine, like a regular diaper. However, the purpose of a swim diaper is only to contain solid waste; the lack of absorbency prevents the swim diaper from swelling up with water.[2] Often reusable swim diapers are lined with a fiber which encourages the solid waste to cling to the fiber without an absorbency layer. A snug fit in the legs and waist are key to function. Brands such as Splash About[3] and The Honest Co.[4] and Beau and Belle Littles [5] utilise tightly knit polyester or neoprene as their material. The disadvantages of a reusable swim diaper is that they must be washed to be reused. On the other hand, a disposable swim diaper is only partially biodegradable and repeated purchases may cost more than reuse. One brand of disposable swim diapers is Little Swimmers, marketed under the Kimberly-Clark Huggies brand. Procter & Gamble produces the rival brand Pampers Splashers. Both are sold in three sizes: small (16–26 lb or 7–12 kg), medium (24–34 lb or 11–15 kg) and large (over 32 lb or 14 kg+). Due to their design for swimwear, they are not as absorbent and not intended for regular diapering. Currently, there are no disposable adult swim diaper options.
