Bags and carriers for wet, muddy boots — the difference between throwing them in the boot of the car and having to valet it afterwards.
Two different things
A welly carrier is cut tall and narrow to take a full-length wellington upright, and is usually the simpler item: a wipeable base, a zip and a handle. The Napier Totem, the Le Chameau tall carry bag, the Härkila Retrieve and the Aigle carrier are all this type.
A walking boot bag is shorter, wider and often compartmented, so a pair of ankle boots sits flat with room for socks and gaiters alongside. The Napier Totem 2 and the Hoggs Field & Trek bag fall here.
What to check
A wipeable plastic base is the feature that matters — canvas alone holds the water and rots. A full-length zip makes loading a tall welly far easier than a top opening, and the Jack Pyke canvas bags take a padlock on theirs if the bag lives in a shared vehicle or a locker.
Boots themselves are in wellingtons and hiking boots. Get them dry before they go in the bag — see boot dryers and footwear care.
