Woodlore Cedar Drawer Liners: Best Overall

Woodlore sets the industry standard for consistent quality, utilizing thick, premium Eastern Red Cedar that delivers a potent, long-lasting scent. These liners are specifically crafted for ease of use, featuring a flexible design that conforms well to the dimensions of standard camping storage bins and dresser drawers. The wood density is high, which translates into superior moisture absorption compared to thinner, perforated alternatives on the market.

This choice is ideal for the dedicated outdoor enthusiast who needs a reliable, “set it and forget it” solution for long-term gear storage. Because the sheets are robust, they don’t curl or warp under the weight of stored base layers or synthetic sleeping bags. If the goal is consistent performance in a humid basement or garage, these liners offer the best balance of longevity and efficacy.

Giles & Kendall Cedar Panels: Best For RVs

Giles & Kendall excels by providing actual planks of cedar rather than thin, paper-backed sheets, making them the superior choice for high-vibration environments like RVs and camper vans. These panels are engineered to be installed directly onto interior walls or storage cubbies, effectively turning any cramped van interior into a climate-controlled cedar closet. The structural integrity of these panels allows them to withstand the constant motion of travel without crumbling or tearing.

For those living out of a van or frequently hitting the road for weeks at a time, these panels mitigate the persistent humidity trapped in tight, unventilated spaces. They provide a structural buffer that keeps bedding and clothing from pressing directly against cold, damp walls, which is a primary cause of condensation build-up. For mobile setups, this is the most professional-grade moisture management available.

Household Essentials Cedar Liner: Top Value

When outfitting a large volume of storage containers or multiple gear closets, the cost of high-end wood can accumulate rapidly. Household Essentials offers a cost-effective alternative that maintains a strong aromatic profile without the premium price tag. While these are thinner than industrial-grade planks, they are perfectly sufficient for maintaining a dry, insect-free environment in climate-controlled areas like a spare bedroom or guest closet.

These liners are best suited for the entry-level enthusiast or the weekend warrior who needs to protect a modest collection of gear without breaking the bank. They are lightweight and easy to trim with standard scissors, allowing for a custom fit in awkward plastic bins or under-bed storage boxes. While they may need to be replaced more frequently than thicker planks, their value proposition for large-scale storage is unmatched.

CedarSpace Aromatic Sheets: Best For Trunks

CedarSpace provides thin, versatile sheets that are specifically designed for interior lining, making them perfect for heritage footlockers, wooden trunks, or specialized camping crates. Their slim profile ensures they do not take up valuable internal volume, allowing gear to be packed tightly without compromising the structural integrity of the cedar itself. The sheets are consistently uniform in thickness, which is a critical feature when lining containers with precise dimensions.

These sheets are the definitive choice for those who store seasonal gear, such as winter mountaineering parkas or summer climbing racks, in wooden containers. Because they are easy to layer, they provide a continuous aromatic shield that keeps moths and moisture at bay during long dormant months. For anyone who uses vintage-style storage for their modern gear, CedarSpace is the functional upgrade needed to ensure long-term preservation.

Richards Homewares Cedar: Best Gear Closet

Richards Homewares offers a diverse range of cedar products that work best when combined to tackle the unique challenges of a walk-in gear closet. Their offerings include versatile hang-ups and flat sheets that create a comprehensive system for protecting technical shells, ropes, and footwear. The ability to mix and match these components ensures that every corner of a closet remains protected from the damp air that plagues basement gear rooms.

This brand is recommended for the enthusiast with a dedicated space who needs to organize a large inventory of varied equipment. Whether hanging damp-sensitive climbing ropes or storing insulated jackets, the variety of shapes provides a targeted approach to moisture control. It is an excellent choice for those who treat their gear closet as an extension of their outdoor activity, prioritizing organization alongside protection.

Prosumer’s Choice Planks: Most Durable Pick

Prosumer’s Choice provides interlocking cedar planks that offer the highest degree of durability among all consumer-grade options. These planks are designed for heavy-duty use in cold-storage environments, such as outdoor sheds or detached garages where temperature fluctuations are extreme. The interlocking mechanism keeps the wood stable, preventing gaps that can allow moisture to bypass the cedar’s protective reach.

If the storage location is prone to high humidity, such as an unheated mudroom or an uninsulated garage, these thick, interlocking boards are the only solution that won’t succumb to environmental wear. They provide a semi-permanent flooring or lining solution that can be reconfigured as your gear collection changes. Investing in this level of durability is the best insurance policy for high-value items kept in challenging, non-climate-controlled spaces.

How Cedar Protects Gear From Humid Climates

Cedar works by naturally absorbing ambient moisture through its porous cellular structure, lowering the overall humidity level within a closed container. This process is essential for preventing the growth of mold and mildew, both of which can compromise the water-repellent (DWR) coatings on modern rain gear. By maintaining a lower relative humidity, cedar prevents the hydrolysis that can break down the polyurethane coatings found on the inside of tents and rain jackets.

Beyond moisture, the natural oils in the wood act as a mild deterrent for pests like moths and silverfish, which are often attracted to the damp environments found in gear storage. This dual-action approach makes cedar a far more effective protector than silica gel packs, which eventually become saturated and stop working. Using cedar turns a simple plastic bin into a protective vault for your most delicate outdoor equipment.

Sizing Cedar Liners For Your Storage Bins

Proper sizing is the difference between a minor moisture issue and total protection. Before cutting, measure the interior base of your storage bin or drawer and allow for a quarter-inch gap at the edges to ensure airflow is not completely restricted. If you are lining a bin with a lid, place the majority of the cedar on the bottom and sides to ensure that the heavier air, which tends to be more humid, is treated first.

For awkward or rounded containers, cut the cedar into strips to create a “slatted” floor, which increases the surface area for moisture absorption. Never block the container’s air vents if they exist, as the goal is to manage humidity, not create a vacuum-sealed chamber. A well-measured liner configuration ensures that every square inch of your expensive gear remains in a consistent micro-climate.

How To Sand And Refresh Fading Cedar Panels

Cedar loses its efficacy when the surface oils oxidize and the scent dissipates, which typically happens every six to twelve months depending on the humidity of the environment. When the wood no longer emits a strong scent, remove the panels and lightly sand them with fine-grit sandpaper to expose a fresh layer of aromatic oils. This simple maintenance step restores the wood’s natural moisture-wicking and protective properties without requiring a new purchase.

After sanding, wipe the boards down with a damp cloth to remove any dust before returning them to the storage area. Avoid using chemical oils or perfumes to “scent” the wood, as these can transfer onto your gear and potentially degrade technical fabrics or rubber components. Proper maintenance ensures that a single investment in quality cedar can last for many years of heavy use.

Maximizing Moisture Control In Camper Vans

In a mobile environment like a van or truck camper, managing condensation is a constant battle during cold or humid nights. Use cedar panels to line the back of storage cabinets where the interior wood meets the cold, exterior metal of the van frame. This creates a thermal and moisture break that prevents the condensation that typically forms on the cold metal walls from seeping into your clothing or sleeping bags.

Additionally, position cedar sheets near the areas where gear is most likely to be damp, such as near hanging wet-weather gear or boot storage zones. The goal in a van is to encourage airflow through the cedar, so avoid packing items tightly against the panels. By allowing the air to circulate across the wood surface, you turn a small, cramped living space into a dry, odor-free sanctuary.

Investing in quality cedar liners is a simple, effective way to ensure your gear survives the humidity that destroys performance materials. By choosing the right product for your storage situation—whether it be a van, a closet, or a plastic tote—you are proactively protecting the equipment that makes your adventures possible. Maintain your cedar annually, keep your gear dry, and you will always be ready for the next departure.
