💦 How to Waterproof Your Gear: A Step-by-Step Guide for Hikers

Rain happens. Creek crossings happen. Sweat? That happens too. The point is: moisture is everywhere on the trail — and it’s your gear’s worst enemy.

So how do you keep your essentials dry in unpredictable weather? Whether you're trekking through misty forests or desert flash storms, waterproofing your gear is a must. Here’s exactly how to do it — with field-tested tips from our HikerHeritage crew.

🌧️ Why Waterproofing Matters

Mike (gearhead): “A soaked sleeping bag in sub-zero temps isn’t just uncomfortable — it’s dangerous. Waterproofing isn’t a bonus; it’s survival.”

Sasha (winter hiker): “Everything I own has at least two layers of protection. Dry gear is warm gear. Period.”

🧰 What You’ll Need

  • Dry bags or stuff sacks
  • Pack liner or trash compactor bag
  • Seam sealer (liquid or tape)
  • Waterproof sprays (DWR reapplication like Nikwax or Gear Aid Revivex)
  • Silicone sealant for silnylon gear
  • Zip-top bags (for electronics)
  • Rain cover for backpack
  • Old towel or tarp (for workspace)

🎒 Step-by-Step: Waterproofing Your Backpack

  1. Use a Waterproof Pack Liner: Line the inside of your backpack with a large trash compactor bag or a waterproof pack liner. This protects everything, even if rain soaks through the outer shell.
  2. Organize Gear into Dry Bags: Separate clothing, sleeping gear, and electronics into individual dry bags or stuff sacks.
  3. Add a Pack Cover: A rain cover helps but doesn’t guarantee dryness. Combine it with internal liners for double-layer defense.
  4. Seal External Pockets: Use zip-top bags for anything in outer pockets. Those are the first to get soaked.

Jake’s Tip: “I skip rain covers and just double-line the inside. Less flapping in high wind, fewer things to rip.”

🥾 Step-by-Step: Waterproofing Hiking Boots

1. Clean Your Boots First

  • Brush off all dirt and mud with a soft-bristle brush
  • Remove laces and insoles
  • Wipe down with warm water and a mild soap

2. Choose the Right Waterproofing Treatment

  • Leather boots: Use wax-based products like Sno-Seal or Nikwax Waterproofing Wax
  • Synthetic boots: Use spray-on DWR products
  • GORE-TEX boots: Use specific GORE-TEX sprays only — don’t clog the membrane with wax

3. Apply Waterproofing Treatment

  1. Apply evenly while boots are slightly damp
  2. Rub in with a cloth or sponge
  3. Let boots sit overnight to fully absorb
  4. Air dry — never use direct heat

⛺ Step-by-Step: Waterproofing Your Tent

1. Inspect Seams and Fabric

  • Look for flaking seams or faded coatings
  • Check rainfly, floor, and zippers for wear

2. Re-Seal Tent Seams

  1. Lay tent flat and clean seams with rubbing alcohol
  2. Apply seam sealer (liquid or tape) along interior seams
  3. Let dry for 12–24 hours before packing

3. Reapply DWR Coating

  1. Set up tent or lay it flat on a tarp
  2. Clean surface with water and sponge
  3. Spray on DWR evenly (follow product instructions)
  4. Let it dry fully in shade

Sasha’s Tip: “Even if it’s brand new, I always reseal seams before a thru-hike. Peace of mind beats puddles in your tent.”

💤 How to Waterproof Sleeping Bags & Pads

  • Use a dry sack for your sleeping bag — compression sacks with roll-top closures work best
  • Always double-bag if storms are forecasted
  • Sleeping pads generally don’t need waterproofing but keep them in dry bags to prevent mold
  • For down bags, use a waterproof bivy or liner inside the tent for double protection

📦 Other Gear to Waterproof

  • Maps & Paperwork: Laminate or store in waterproof map cases
  • Electronics: Keep in zip-top bags or waterproof phone pouches
  • First Aid Kits: Store in hard plastic or sealed waterproof pouch
  • Food: Use odor-proof, waterproof bags like OPSAK or double-zip freezer bags

🛠️ Maintenance Tips

  • Reapply DWR spray once or twice per season (or after each multi-day trek)
  • Dry all gear fully before storing — even “waterproof” materials can develop mildew
  • Inspect for tears and reseal seams after every trip
  • Never pack wet gear — it will degrade faster than you think

🧵 Final Thoughts: Stay Dry, Hike Farther

Moisture is one of the biggest enemies on the trail — but with a little prep and the right waterproofing steps, you can turn your gear into a fortress against the elements.

And remember: no waterproof system is perfect. It’s all about layering your protection — dry bags inside liners inside rain shells. Redundancy = reliability.
