The invention relates to an improved, inflatable liner for a helmet. The liner employs hook and loop fasteners for easy removal and attachment to the inner surfaces of the helmet shell. The liner incorporates a fluid impermeable enclosed volume which may be inflated with water (or air). A valve provides access to the enclosed volume. The liner is of a light-weight, open-framed, semi-hemispheric configuration which allows for air circulation. A soft material is disposed on the open frame structure creating a buffer between the wearer's head and the helmet. A soft, moisture-absorbent fabric encompasses the periphery of the liner. The absorbent fabric functions as a sweatband for absorbing perspiration and for protecting the wearer's forehead from rubbing against the helmet shell.
