Our leather is tanned naturally by plant enzymes instead of chemicals (chrome). The vegetarian tanning process is a long process done with oil and extract/juice of bark, plants, branches, roots, and seeds. Tanning with plants is extremely in-depth and up to 80% of the tannic acid is absorbed into the leather, thus leaving little surplus material - what is in excess is even 100% biodegradable. Vegetable-tanned is generally very durable compared to leather tanned with chemicals and very environmental friendly. One of the best features in organically tanned leather is the reduced risk of skin irritation and allergies. Feel the difference!
