Storing important documents such as permits in extreme weather conditions can be a major challenge.
Many standard document wallets simply won’t last the required duration. Document wallets are commonly made from PVC which will go brittle when exposed to low temperatures. This can then result in the wallet shattering under impact meaning the enclosed documents are exposed to the elements. In addition, standard document wallets often are sealed with a zip. This in turn can be very difficult to operate if the wallet is in cold conditions or if the operator is wearing gloves.
