Product Care

MATERIALS

Semper Fi Leather uses vegetable tanned leathers that have been produced in Chicago at the Horween Leather Factory. The vegetable tanning process utilizes natural tannins obtained from plant matter to preserve and colour the hide. It is one of the most traditional, natural, and environmentally friendly methods of tanning. The resulting leather is strong and beautiful, gets better with age, and will biodegrade when its functional lifespan is complete.

We use solid brass hardware and YKK zippers because we like how they last. All of our hardware and zippers are sourced within the states.  

We use heavy-duty thread, because we think it’s important that our thread is as strong and durable as the leather we use.  

PRODUCT CARE

Vegetable tanning preserves leather in its strongest and most natural state, maintaining the characteristics that make each hide unique. Surface markings remain visible: pores, scars and variations in color are not disguised. The more the natural skin structure is visible, the less the leather has been industrially processed. These markings are simply signs of the quality of the material. The leather used to make our goods will develop a darker, richer patina that will reflect the wear and care it receives - making the item more personal with each and every use. Vegetable tanned leather should only be treated with natural products to maintain the breathability of the leather, and to preserve the natural ageing process.

Semper Fi Leather products are handcrafted. Remnants of this process will be noticeable, reminding us of the origin and production process of the finished item.

The color of some leathers can bleed. Please take extra care with new leather items and avoid contact (especially excess rubbing) with light-colored clothing or furniture.

 

EXPOSURE TO ELEMENTS

Water:

Vegetable-tanned leather is not colour stable in water. On lighter leathers, water will generally leave darker marks. Some appreciate the markings, seeing them as yet another contribution to a beautifully aged and personalized patina. If you are not one of these people, prevention is key. We recommend using Chamberlain’s Leather Milk water protectant No.3 to prevent water damage. If your leather does get wet, simply use a clean, slightly damp cloth to wipe off any splattered mud or dirt, and allow to dry naturally. Never use any form of heat to dry leather. If vegetable tanned leather is allowed to become thoroughly water soaked or it gets heavily rained on repeatedly, it may be a little less supple once it dries. Using a natural conditioning product can help.

Sun:

Never leave leather items in direct sun for a prolonged period of time, as this can dry out and affect the color of the leather.

 

CLEANING

The cleaning of heavily soiled or stained leather items is best left to a professional that specializes in cleaning vegetable tanned leather. In instances where all that’s needed is a light touch-up, we recommend using Chamberlain’s Leather Milk straight cleaner No.2.

 

CONDITIONING

The natural oils and fat liquors used in the tanning process help to keep the leather supple and well-protected. As your leather ages, we recommend conditioning it occasionally with a leather conditioner such as Chamberlain’s Leather Milk Leather Care Liniment No.1. Always test new care products on an inconspicuous area of the bag to assure the color of the leather will not be altered in an undesired way.

 

STORAGE

We send out a dust bag with all of our goods. Go ahead, use it - preferably in a dry area, away from direct heat or sun. Never store leather in plastic. Leather, like us, needs access to fresh air.
