Twice prior I have taken with me as checked airline baggage a 4’ long cardboard shipping tube (4” diameter when solo and 6” diameter with partner along). In it I ship trekking poles and other needs including packing tape for resealing the ends. Once in Scotland, I remove from it the items I need for my crossing. Thereafter, I send the tube by postal service ice to The Park Hotel in Montrose. I try to launder my travel clothes before tubing them so they are fresh to wear at Montrose. Works like a charm.

So says I.
