The invention is directed to a planar pad manufactured from three bonded layers each having different properties and materials. This includes a contact layer having a first and corresponding second portion. The second portion overlaps the first portion sufficient to create a first overlay. Such contact layer may be made of fibers which include silver nano-particulates. The contact layer may also include a coating made of TEFLON or similar material. The second layer is an absorbency layer positioned immediately below the contact layer. The absorbency layer being made of natural woven bamboo fiber. In addition, the absorbency layer may be two-part construction having a first absorbent portion and a corresponding second absorbent portion which abuts the first absorbent portion, wherein both absorbent portions have fused sides to reduce fraying. The third layer is a waterproof barrier layer which is posited directly below the absorbency layer, preferably constructed of TYVEK.

The invention provides an ultralight breathable environmental-friendly bedding and a preparation process thereof. The ultralight breathable environmental-friendly bedding is formed by splicing a hometextile fabric and a cordura fabric. The home textile fabric selects and uses a tabby, twill or tribute silk fabric; and the cordura fabric is cordura cloth 1443R.
