PERSPIRATION WICKING AND ABSORBING SPORTS SHIRT

CHEMISE SPORT ABSORBANT LA TRANSPIRATION ET A TISSU MECHE

English Abstract

The invention is a sports shirt designed for use by hikers and cross-country
skiers who
wear a backpack or fanny pack.
The invention is used to wick and store perspiration away from the wearer's
back when
evaporation of perspiration from one's back is greatly limited by the pack.
The sports ship consists of an internal layer of hydrophilic man made fabric
which wicks
perspiration away from the body.
Upon the rear panel of the shirt, a mid layer of highly absorbent fabric is
fixed and
permanently installed. The perspiration is wicked by the internal hydrophilic
layer into
this absorbent layer for storage away from the skin.
Upon the mid layer, an external layer of fabric is fixed and permanently
installed. This
layer is essentially for both aesthetics and to protect the absorbent layer.

-4-
The embodiments of the invention, in which an exclusive property or privilege
is
claimed, are defined as follows:
1. A sports shirt having a main body destined to fit onto a wearer's
torso and defining a front and rear panel and sleeves of hydrophilic man made
fabric
integrally linked to each other, said shirt having a panel of absorbent fabric
integrally
linked to the exterior of said rear panel and having an additional layer of
fabric integrally
linked to the exterior of the two aforementioned rear panels.
2. A sports shirt as defined in claim 1, wherein said sports shirt main
body defines a neckline, a hem at the lowest torso portion, and a pair of
sleeves of
hydrophilic man made fabric
3. A sport shirt of hydrophilic fabric as defined in claim 1, having an
additional panel of highly absorbent fabric integrally linked to the exterior
of said
hydrophilic layer on the entire rear panel.
4. A sport shirt of hydrophilic fabric as defined in claim 1, having an
additional panel of highly absorbent fabric integrally linked to the exterior
of said
hydrophilic layer on any portion of the rear panel.
5. A sport shirt of hydrophilic fabric as defined in claim 1, having an
additional panel or more, of highly absorbent fabric integrally linked to the
exterior of
said rear hydrophilic layer.
6. A sports shirt of hydrophilic fabric as defined in claim 1, having an
additional panel of highly absorbent fabric integrally linked to the anterior,
clavicular
shoulder area of the aforementioned hydrophilic layer.
7. A sports shirt of hydrophilic fabric as defined in claim 1, having an
additional layer of highly absorbent fabric integrally linked to the exterior
of the
aforementioned hydrophilic layer of fabric.

-5-
8. A sports shirt of hydrophilic fabric as defined in claim 1, having a
layer of fabric integrally linked to the exterior of the absorbent layer on
the back panel.
9. A sports shirt of hydrophilic fabric as defined in claim 1, having
a layer of fabric integrally linked to the exterior of the absorbent layer on
the anterior,
clavicular, shoulder area.
10. A sports shirt of hydrophilic fabric having a layer of absorbent
fabric integrally linked to the exterior of the rear panel, which is in turn
covered by a
layer of hydrophilic fabric and integrally linked to the hydrophilic and
absorbent layers
11. A sports shirt of hydrophilic fabric as in claim 1 , having a layer of
fabric integrally linked to the exterior of the absorbent layers, as in claim
7.
Said sports shirt is destined to draw perspiration from the body so that it
may evaporate, except for the rear panel, where the internal hydrophilic layer
is destined
to draw perspiration from the back, shoulder and buttock regions into said
internal highly
absorbent layer for "storage".

TITLE OF THE INVENTION: PERSPIRATION WICKING
AND ABSORBING SPORTS SHIRT
FIELD OF THE INVENTION:
The present invention relates to perspiration absorption, and more
particularly, to a shirt that allows cross-country skiers, hikers and
cyclists, who are
wearing a backpack, to remain dryer underneath their packs.
BACKGROUND OF THE INVENTION:
The inventor, faced with the problem of a wet shirt hack common to all
Individuals wearing a backpack, improvised a perspiration absorbing layer on
top of his
back, for the purpose of solving the problem.
He designed prototypes, tested them and performed market studies in
order to ascertain whether the market would readily accept the eventual
solution.
Previous inventions to solve the wet back problem have been directed
toward altering the packs themselves. This has been done in such a manner, as
to allow
for greater circulation of air between the back and the backpack itself.
Gregory Outdoors, an American backpack manufacturer attempted to
solve the problem using a molded back of a pack with air channels for
circulation. This
does not solve the perspiration problem when one is wearing a jacket.
In patent no. CA2323306, Gordini USA attempts to solve the problem:
"A weight supporting and ventilating system shifts the weight of the backpack
and its
contents to the user's waist and hips and provides an airway for ventilation
between the
backpack and the user's back." This is not recommended because the pack will
likely
sway. The perspiration problem will continue under the shoulder and waistlhip
straps.

The invention allows for the wearer to continue using his present packs in
relatively dry comfort, without having to invest in additional backpacks as it
can be used
with both existing day and expedition packs.
The invention may also be used by automobile or truck drivers on hot
days to absorb perspiration upon their backs as they sit on their seats.
OBJECTS OF THE INVENTION AND HOW IT ADDRESSES A TECHNICAL
PROBLEM:
The primary goal of the invention is to provide a sports shirt ( 1 ) having
integral layers that can absorb and then store perspiration.
The secondary goal of the present invention is to provide a shirt that
helps prevent hypothermia by keeping the skin of the wearer's back dry.
A hydrophilic layer (2) wicks perspiration away from the skin directly
into an absorbent layer of fabric (3), which is external to the hydrophilic
layer (2). This
prevents the accumulation and gravitating of perspiration, to the lower back
and buttock
regions, as would be associated with other sport shirts, hydrophilic or not.
The hydrophilic layer keeps the perspiration wetness away from the skin.
DESCRIPTION OF THE INVENTION:
The present invention relates to a sports shirt that allows those wearing a
backpack to avoid the accumulation of perspiration in their garments.
This accumulation occurs in the shoulder and lumbar region and is
caused by the contact of the pack and it's straps with the wearer's back.
During vigorous
physical activity perspiration accumulates within the fabric of the shirt and
shorts/pants.
Specifically, the present invention is a sports shirt comprised of a
hydrophilic layer (2), having a main body adapted to fit onto a wearer's torso
and
defining a front and rear panel integrally linked to each other, said rear
panel having a
panel of highly absorbent fabric (3) integrally linked to it's exterior and
subsequently, an

additional layer of fabric integrally linked to it's exterior (4), hence
enveloping said
absorbent layer (2) by the hydrophilic (3) and exterior layers (4).
ONE EXAMPLE OF INTENDED USE
The invention could be worn by a cross-country skier who is wearing a
backpack and wishes to avoid having the wet back that will inevitably develop
due to the
lack of the evaporation of perspiration from the skier's back.
