PANTIES Russian patent published in 2011 - IPC A41B9/04 

FIELD: personal use articles.

SUBSTANCE: invention relates to a pair of panties, designed for use mainly by sporstmen or other active people and containing a belt part (2), joined to the rear and front parts (3, 4), which near the user's crotch (5) are interconnected or matched with each other to form a crotch part (6), which at its inner side contains a layer (7) of air impermeable and moisture-transporting material to ensure ventilation of the user's lower belly part. The layer (7) of the material has the width, which mainly corresponds to the width of the crotch part of the panties pair (1), and the length passing forward at the specified distance and backward from the middle of the crotch part (6), and in compressed condition it retains an air passage to ensure the possibility of air circulation above the user's crotch, and also both deep down and in longitudinal direction via the layer (7) of the material. At the same time the conditioning zone is formed by means of both air exchange and drainage of the crotch part (6) in an active manner through the structure of the material layer (7), and the specified structure of the material layer (7) consists of directly the crotch part (6) or indirectly the supporting layer (11, 12, 12', 12"), attached to the crotch part (6), and air channels (14, 21), which protrude from it and passing through the surrounding fibrous material (7', 7") or flexible thread- and/or strip-like material (8).

EFFECT: invention achieves very intense evaporation of body fluids, and a channel or a layer remains during compression, which allows for intense air exchange, fluids and moisture are released from the pair of panties without prevention of air exchange itself.
