Snowboard pants take on a lot over the course of a season. Sweat, snow, mud from the parking lot, and the occasional spill in the snow all build up over time. Eventually, they need a proper wash. But snowboard pants are not like regular clothing, and washing them the wrong way can ruin the waterproofing and breathability that make them work in the first place.
This guide walks through the safest way to wash snowboard pants so they stay waterproof, breathable, and ready for the next storm.
Why Snowboard Pants Need Special Care
Most snowboard pants are built with a waterproof and breathable membrane, often something like Gore-Tex or a similar proprietary technology. This membrane is coated with a durable water repellent finish, usually shortened to DWR, which helps water bead up and roll off the surface instead of soaking in.
Regular laundry detergent and hot water both damage this coating over time. Detergent leaves behind residue that clogs the breathable membrane, while heat can break down the waterproof layer entirely. Washing your pants the wrong way even once can noticeably reduce how well they perform in wet snow.
Check the Care Label First
Before washing, always check the care label sewn into your pants. Manufacturers include specific instructions based on the exact fabric and membrane used in that particular pair. Some pants can handle a gentle machine wash, while others recommend hand washing only.
If the label has faded or is missing, treat the pants as delicate technical gear. Use cold water, a gentle cycle, and skip the dryer entirely unless you know for certain the manufacturer allows it.
What You Will Need
A few supplies make the process much easier and help protect the fabric. A technical gear cleaner made specifically for waterproof outerwear, such as Nikwax Tech Wash or Grangers Performance Wash, works far better than regular detergent. These cleaners rinse out completely without leaving behind residue that clogs the membrane.
Avoid regular laundry detergent, bleach, and fabric softener entirely. Fabric softener is especially damaging, since it coats the fibers and destroys the breathability that waterproof membranes depend on to function properly.
Preparing Your Pants for Washing
Start by emptying all pockets and closing any zippers, velcro straps, or snaps. Open zippers or hooks can snag on the fabric during the wash cycle and cause small tears or pulls. Turn the pants inside out as well, since this helps the wash cycle clean sweat and body oil buildup on the inner lining more effectively.
Brush off any dried mud or debris before washing. Loose dirt can scratch the fabric surface during the wash cycle and reduce the effectiveness of the water repellent coating.
Machine Washing Snowboard Pants
Most snowboard pants can go in the washing machine as long as you follow a few important guidelines. Use cold or lukewarm water, never hot, since heat is one of the biggest threats to the waterproof membrane. Select a gentle or delicate cycle to avoid unnecessary agitation that can wear down seams and coatings over repeated washes.
Add a small amount of technical gear cleaner instead of regular detergent, following the amount recommended on the product packaging. Skip the fabric softener dispenser completely, even if your machine prompts you to use one.
Washing pants alone or with a small load of similar technical gear works best. Mixing them with regular clothing like jeans or towels adds unnecessary friction that can wear down the outer fabric faster than normal.
Hand Washing for Extra Care
If your pants are labeled hand wash only, or if you simply want the gentlest option available, hand washing works well too. Fill a bathtub or large basin with cool water and add a small amount of technical gear cleaner.
Submerge the pants and gently agitate them with your hands, paying attention to areas with heavy dirt buildup like the cuffs and knees. Avoid scrubbing too hard, since this can wear down the waterproof coating over time. Rinse thoroughly with clean water until no soap residue remains, since leftover soap can reduce breathability once the fabric dries.
Drying Snowboard Pants Correctly
Drying is one of the most important steps, and rushing it with high heat can undo all the care taken during washing. Check the care label first, since some technical fabrics actually benefit from a low heat tumble dry cycle, which helps reactivate the water repellent coating.
If the label calls for air drying, hang the pants somewhere with good airflow, away from direct sunlight or heat sources like radiators. Avoid drying pants flat if possible, since hanging allows better airflow around the entire garment and speeds up drying time.
If tumble drying is allowed, use a low heat setting only and check the pants periodically. Some manufacturers recommend adding a few clean tennis balls to the dryer, which helps redistribute the water repellent coating evenly across the fabric as the pants tumble.
Reapplying Waterproofing After Washing
Even careful washing wears down the factory applied water repellent finish over time. After a few wash cycles, you may notice water no longer beads up and instead soaks into the fabric surface.
Once your pants are clean and completely dry, apply a waterproofing spray or wash in product made for technical outerwear. Follow the specific product instructions for application, since some require reactivating with gentle heat from a dryer or iron on a low setting. Test the pants afterward with a few drops of water to confirm the coating is working properly again.
How Often Should You Wash Snowboard Pants
Snowboard pants do not need washing after every single use. Overwashing actually accelerates wear on the waterproof coating and fabric over time. A good approach is to wipe down any visible dirt or mud after each trip and save a full wash for every five to ten uses, or sooner if they start to smell or visibly lose their water repellency.
Always wash pants at the end of the season before storing them away for the summer months. Leaving dirt, sweat, and oils in the fabric over a long period of storage can cause staining and odor that becomes much harder to remove later.
Common Mistakes to Avoid
A handful of habits can shorten the lifespan of snowboard pants significantly. Washing in hot water damages the waterproof membrane and can cause shrinkage in certain fabrics. Using regular detergent or fabric softener leaves behind residue that clogs breathable membranes and reduces performance.
Skipping the waterproofing reapplication step after several washes is another common mistake, leading to pants that soak through even though they were technically clean. Storing pants while still damp can also lead to mildew and lingering odor issues that are difficult to fully remove.
Storing Snowboard Pants for the Off Season
Proper storage at the end of the season protects your pants just as much as washing them correctly. Make sure pants are completely clean and fully dry before folding or hanging them for storage. Store them in a cool, dry place away from direct sunlight, which can degrade fabric and coatings over long periods of time.
Avoid sealing pants in airtight plastic bags for extended storage, since trapped moisture can lead to mildew even in pants that seemed dry at the time. A breathable garment bag or simply hanging them in a closet works better for long term storage between seasons.
Final Thoughts
Washing snowboard pants correctly comes down to a few key habits. Stick to cold or lukewarm water, use a technical gear cleaner instead of regular detergent, and follow the care label for drying instructions. Reapply waterproofing when needed to keep water beading off the surface rather than soaking in.
A little extra care during washing goes a long way toward keeping your pants performing well season after season, so you can stay dry and comfortable no matter what the mountain throws at you.
