The wallet (10) comprises male and female fasteners for engaging the flap portion (26) with the front panel (14). The wallet (10) includes a tether (32) that extends from the rear panel (16) of the pocket portion (12). The tether (32) includes a plurality of fasteners (34), (36), (38) spaced from one another for folding the tether (32) upon itself to define loops of different sizes, i.e. different configurations for various attachments.
