Lifesystems anodised mountain whistle on keyring

It's always recommended that anyone who is spending time outdoors should  carry a whistle at all times. This one is lightweight with a tough anodised alloy body, and a handy keyring to attach it to your daysack zipper etc.

To signal for help using a whistle or torch, use the old-fashioned Morse code SOS signal.
