Abstract: Systems and methods are provided to facilitate the sharing of account features. In one aspect, a system includes a transaction handler to process transactions and a data warehouse to record the transactions and store account data identifying account features of separate accounts, such as a second account having a feature and a first account without this feature. Account holders of the first and second accounts are in a same household and thus, in accordance with a set of rules, eligible to share the account features. A portal is configured to receive a request identifying the first account and to determine whether a transaction initiated in the first account and qualified for a benefit of the account feature is entitled to the benefit; and if so, a notification engine is to transmit a notification message to an account holder of the first account.

Abstract: A sleeping bag allows users to adjust the bag between a conventional rectangular bag and a narrowed mummy-style bag, thereby adjusting the internal volume of the bag. This allows a user to reduce the inner air space of the bag forming a tapered mummy-style shape for maximum comfort in cold weather. The sleeping bag user may also expand the inner space of the bag into a non-tapered, substantially rectangular shape for maximum comfort and freedom of movement in warm weather. This adjustment may be accomplished quickly and easily via one or more secondary external zippers or a system of toggles and loops, allowing the sleeping bag user to respond to even sudden changes in temperature.
