The Filson rugged twill 70232 is renowned for their durability and iconic waxed finish, designed to brave the elements and last for generations. However, like any great outdoor gear, a bit of maintenance can go a long way. In this guide, we will walk beginners through the process of rewaxing a Filson Rugged Twill Medium Field Bag to restore its water resistance and unique aesthetic aging appeal.
Why Rewax Your Filson Bag?
Wax serves as the frontline defense for your Filson bag, repelling water and preventing wear and tear. Over time, this protective wax layer can thin out, leading to a faded appearance and compromised durability. Rewaxing restores this protective shield, keeping your bag looking sharp and resistant to the elements.


You need to prepare the following tools:

These items will help apply and distribute the wax evenly across the bag’s surface, achieving a clean, professional finish.
- A pair of rubber gloves
- A sponge
- Filson oil finish wax
- Hair dryer
Before you start the rewaxing process, ensure your bag is neat and dry. Gently clean it using a slightly wet cloth and let it air-dry naturally. Don’t forget to prepare the space where you’ll be working. The waxing process can get a bit untidy, so it’s a good idea to spread some old newspapers or a used piece of cloth to shield your workspace from potential messes.
Here’s a straightforward guide to rewaxing:
Step 1: Remove the shoulder strap and put a cloth under the bag.
Step 2: With a brush or cloth, evenly spread Filson’s Original Wax onto your bag.
Step 3: After the wax has been applied, utilize a hairdryer or heat gun set to low to help the wax infuse into the fabric. Make sure to continually move the heat source to prevent any area from getting too hot.
Step 4: Once the wax has melted into the fabric, take a clean cloth and gently spread the wax to ensure it’s uniformly distributed across the bag.
Step 5: After your bag has been fully waxed, allow it to air dry. This process may take several hours, so patience is key here.
It is worth noting that this waxing process is only on the front flap of the bag, and the inside and back are not waxed.
The process can also be simply divided into two stages:
Stage 1 : Primary Waxing

Apply wax to the surface of the bag and make sure to spread the wax evenly and excessive use of wax will turn the canvas dark. Use the sponge to wipe the excess wax at the seams. Use a hair dryer to melt the wax into the fabric when the initial waxing is complete.
Stage two : Secondary waxing

Apply a small amount of wax to the seams that are unevenly heated or not applied, and reheat it again. After the melted wax covers the surface of the bag, choose a ventilated place or balcony to let it dry and shape.
Post-Rewaxing Care
Once you’ve finished rewaxing, make sure to tidy up your used tools and keep them in a safe place for next time. For the best care of your newly waxed Filson bag, stow it in a location that’s cool and dry to preserve the wax’s fresh look. With habitual use of your bag, it’s a good idea to plan for a rewaxing routine every six to twelve months. This way, your bag can always be at the top of its game in both appearance and function.
In conclusion, rewaxing your Filson Rugged Twill Medium Field Bag not only restores its aesthetic appeal but also enhances its durability and water resistance. The process might seem daunting for beginners, but with a bit of patience and practice, you can easily maintain the timeless charm of your Filson bag.
