A quality set of trekking gear — boots, down jacket, backpack, sleeping bag — represents an investment of $1,000–3,000 USD. Properly maintained, that gear lasts 10–15 years and accompanies you across multiple Himalayan treks. Neglected after a single trip, the same gear may degrade significantly in 2–3 seasons.
Nepal's mountain environment is harsh on equipment: the combination of dust, sweat, UV radiation, moisture from river crossings and monsoon rain, and freeze-thaw cycles at high altitude accelerates degradation faster than most trekking environments. Post-trek maintenance is not optional if you want to protect your investment.
This guide covers the care protocols for each major gear category, the on-trek maintenance that prevents problems from developing, and a comprehensive post-trek checklist.
Trekking Boots
On the Trek: Daily Care
Dry boots overnight. Wet boots develop internal mold, cause blisters, and degrade the bonding between sole and upper. After each trekking day, remove insoles and stuff boots loosely with newspaper or dry fabric to absorb moisture. Set them away from the fire (direct heat warps synthetic uppers and cracks leather) but in a warm, dry spot.
Clear mud and debris daily. Caked mud holds moisture against the upper and can harbour bacteria that degrade leather. Use a brush (a basic boot brush) to clean after each day.
Dry-camp care in high altitude: At altitude, temperatures can drop below -15°C overnight. Wet or even damp boots left outside will freeze solid and be unwearable in the morning. Keep boots inside your sleeping bag cover or in the lodge room.
Post-Trek Boot Care
Step 1: Clean thoroughly. Remove laces and insoles. Use a stiff brush under running water to remove all mud and trail debris from the upper, welt, and sole. Use a soft cloth for suede or nubuck uppers. Allow to air dry completely at room temperature.
Step 2: Condition leather (leather boots only). Once dry, apply a quality leather conditioner (Nikwax Leather Conditioner, Sno-Seal, or manufacturer-recommended product). This replaces the oils that trail use and cleaning deplete. Without conditioning, leather cracks and stiffens.
Step 3: Re-waterproof. Nepal's trails expose boots to water from stream crossings, rain, and snow. The DWR (Durable Water Repellent) coating applied during manufacturing degrades with use and washing. After 2–3 major treks (or when you notice water soaking into the upper rather than beading), reapply:
- Leather boots: Nikwax Leather Wax or Grangers One For All wax
- Synthetic/fabric boots: Nikwax Fabric and Leather spray, or Grangers Footwear Repel
Apply according to product directions; most require slightly warm boots for application and allow 24–48 hours before next use.
Step 4: Replace insoles if worn. Insoles compress over time, reducing cushioning and stability. After a 14-day Nepal trek with 8-hour days, most insoles show significant compression. Superfeet, Sole, and similar aftermarket insoles outperform stock equivalents and last longer.
Step 5: Inspect sole attachment. The welt and glue bond between sole and upper is the most common failure point in trekking boots. If you see any separation beginning, use Barge Cement (contact cement designed for footwear repair) or take to a cobbler immediately. A sole delaminating mid-trek in the Khumbu is a genuine problem.
Storage
Store boots dry, away from direct sunlight (UV degrades synthetics), in a cool, ventilated location. Boots stored in sealed plastic bags or compression sacks develop mold. Loose newspaper inside boots maintains shape during storage.
Down Insulation (Jackets and Sleeping Bags)
Down insulation is the highest-maintenance category in a trekker's kit. Wet, compressed, or contaminated down clumps and loses its insulating air space — potentially dramatically.
On the Trek: Down Care
Keep dry. Down's Achilles heel is moisture. A wet down jacket loses most of its insulative value. In wet conditions (rain, stream crossings, high humidity), store your down inside a dry bag in your pack. Only bring it out when needed.
Air daily. Body oils and moisture accumulate in down used frequently. Where possible, air your sleeping bag for 30–60 minutes each morning before packing. The UV and airflow help maintain loft.
Spot clean on trek. If you spill food on your down jacket, spot clean immediately with a small amount of technical fabric cleaner and a cloth. Food attracts wildlife and the oils degrade down clusters.
Washing Down: The Critical Protocol
Do not dry clean down. Perchloroethylene, the standard dry-cleaning solvent, strips the natural oils from down and causes irreversible damage. Machine wash or hand wash with down-specific detergent only.
Machine washing:
- Use a front-loading machine only (top-loaders with agitators can tear down clusters)
- Use down-specific detergent (Nikwax Down Wash Direct, Granger's Down Wash)
- Gentle or delicate cycle, cold water
- Extra rinse cycle (repeat if needed until water runs clear — down can retain soap)
- Tumble dry LOW heat with three clean tennis balls (or dryer balls)
- The dryer stage is critical — down must be fully dry or mold will develop. Plan 2–4 hours for a jacket; 4–6 hours for a sleeping bag
- Break up clumps by hand periodically during drying
When the DWR on your down jacket stops working: The shell fabric of most down jackets has a DWR coating that causes water to bead off rather than soaking in. When this fails and the shell "wets out," the insulation inside becomes compressed even if it hasn't actually penetrated to the down. Restore DWR by:
- Washing the jacket
- Tumble drying on LOW heat for 20–30 minutes — heat reactivates DWR
- If still not beading, apply Nikwax Down Proof or Granger's Down Proof spray
Sleeping Bag Care and Storage
On trek: Sleep in clean sleeping clothes to minimise oils and body moisture contaminating the down. Use a sleeping bag liner if you have one — it adds warmth and protects the bag.
Post-trek washing: Same protocol as down jackets above. Most sleeping bags for Nepal trekking (rated to -10 to -20°C) are substantial items — allow 6–8 hours of drying time.
Storage (critical): Never store a down sleeping bag in its compression sack. Permanent compression damage the down clusters. Store in the large mesh storage bag that comes with quality sleeping bags, or loosely in a breathable cotton pillowcase. A properly stored sleeping bag retains its loft for 10–15 years.
Backpacks
On the Trek: Pack Care
Dry completely after wet days. Empty the pack, open all pockets and compartments, and allow to air dry. Internal frame pockets in particular can harbour mold if stored damp.
Reapply DWR if needed. Most pack fabrics lose water repellency after heavy use. Use Nikwax Tech Wash (general spray) or similar.
Post-Trek Cleaning
- Empty completely and shake out debris
- Hand wash with mild soap and water — use a soft brush on the hipbelt padding and shoulder strap foam where salt from sweat accumulates
- Rinse thoroughly
- Air dry fully before storage (frame pockets need particular attention — turn them inside out to dry)
- Inspect frame elements for cracks or bends that might have occurred during airline transport
- Check all buckles — particularly hipbelt buckles, which take the most stress
- Lubricate metal zipper sliders with beeswax or Ziptech stick
Washing machine: Some packs can be machine-washed on gentle cycle (check manufacturer guidelines). Never machine dry a backpack — heat deforms frame elements.
Repair
Torn fabric: Tear Aid (a flexible transparent adhesive tape) repairs most fabric tears instantly without sewing. For structural tears near seams, McNett UV Seam Sealer provides a permanent fix.
Broken buckles: Side-release buckles snap from falls or airline baggage handling. Replacement buckles in all standard widths cost $1–2 and can be switched without sewing by sliding off the webbing.
Broken zipper: A zipper slider that no longer closes can often be fixed with pliers — gently squeeze the slider to tighten it. Replacement zippers can be soldered or sewn at any Kathmandu tailor (several operate in Thamel specifically for trek gear repair).
Trekking Poles
Clean and dry after wet days. Extend poles fully and rinse with fresh water. Shake vigorously to clear water from the locking mechanisms. Allow to dry fully before collapsing.
Check locking mechanisms. Twist-lock poles should tighten smoothly without slipping. If a pole collapses under weight, the locking mechanism needs adjustment or replacement — do not use a pole that slips under load.
Cork grips: Cork grips develop mold if stored damp. Wipe with a damp cloth, allow to dry fully.
Carbide tips: Replace worn carbide tips annually if you trek frequently. New tips cost $5–10 at gear shops in Kathmandu.
