BACKGROUND

1. Field of the Invention

The present invention generally relates to caps and headwear. More particularly, the present invention generally relates to cap liners for various helmets.

2. Description of the Related Art

Helmets are required for various sporting activities, including activities in both warm and cold environments. Unfortunately, helmets generally exhibit poor thermal properties and, therefore, do not greatly enhance the wearer's comfort in cold environments.

Recently, SKULLY cap liners have been increasingly worn by athletes under helmets when participating in sporting activities in colder environments. Such SKULLY cap liners are typically made from polyester and help wick away moisture from the wearer's head and provide a non-slip surface for the helmet. Consequently, SKULLY cap liners allow the helmets to better stay on due to the non-slip surface and also provide more comfort for the wearer.

However, SKULLY cap liners exhibit a number of deficiencies. First, SKULLY cap liners are typically only made of polyester; thus, there are limited materials that can be used to produce such cap liners. In addition, SKULLY cap liners are woven articles and, therefore, typically have a large number of seams due to the sewing of the woven fabric. Consequently, the large number of seams can cause discomfort to a wearer. Furthermore, due to the simplicity of material used to produce the SKULLY cap liners, the cap liners have limited features specially adapted for cold weather. Therefore, SKULLY cap liners do not optimize the warmth of a wearer during cold weather.

SUMMARY

One or more embodiments of the present invention generally concern a cap liner for a helmet. Generally, the cap liner comprises: (a) a cap body, wherein the cap body comprises an upper end portion comprising a first mesh structure; (b) a neck retainer, wherein the cap body and the neck retainer are integrally connected; (c) an eye opening positioned in the cap body; (d) a first ear position positioned in the cap body, wherein the first ear position comprises a second mesh structure; (e) a second ear position positioned in the cap body, wherein the second ear position comprises a third mesh structure; (f) a nasal ventilation positioned in the cap body, wherein the nasal ventilation comprises a fourth mesh structure; and (g) a mouth ventilation positioned in the cap body, wherein the mouth ventilation comprises the fourth mesh structure or a fifth mesh structure.
