The Perch.

I've mentioned it a time or two now.  I took it with me the day we went to Rannerdale, about mid may.  I could have sold 1/2 doz. if I'd had them.
    Out of a bit more out of curiosity than anything - SO - I weighed them.  Rounded up/down to 5gm.
    The Perch   -   1190 gm

Right - Longer to wear like a "Shoulder Bag".
