Our Rugged Twill Log Carrier embodies the philosophy that's guided Filson since 1897, making products that are handed down rather than tossed out. The Rugged Twill fabric is an industrial-strength fabric from historic British mills. It's lightly waxed for water and stain resistance. The Bridle Leather used for the handles is strong and durable enough for horse tack. It's been slowly vegetable-tanned over several weeks in plant-based solutions. This all-natural process transforms top-grade cowhides into sturdy leather that provides decades of service. The handles are attached with rivets for maximum strength.
