Of Course, Cob is Nice Choice!
But I recommend Cob rather than Briar.
It's hard, so you can just throw it in your bag, and you don't have to worry about breaking it.
If you are worried about the tenon breaking down,
it is also a good idea to separate the stem from the stummel and put it in the bag.
I sometimes go fishing for 2 days, and I bring the briar pipes for less than 100 dollars.
When a lot of fish is bite, they wait for me with the wet ash and tobacco.
In Korea, pipes that are used in harsh environment are called 'pipes for Combat'.
