Finnish Cotton-Canvas Respirator H'sack. Supergrades.
Here we have a selection of our top grade - best of the best - all sorted from rapidly diminishing stock and, not ever, being replaced in this genre.
Fantastic quality mid-sized haversack ideal for a bimble in the woods or as a work bag for your flask and sarnies.
Easily takes a water bottle and ancillaries - thick-sliced bread may be a problem though!
Note: there are many variations of this bag so exact spec may vary.
