A trusty synthetic sleeping bag is comfy, stays warm when damp, and ready for adventure. But if you want it to last, keeping it clean and well-maintained is key. Don’t worry—washing your sleeping bag isn’t as daunting as it sounds. Let’s break it down so you can do it the right way.
Before you get started
The good news? You don’t need to wash your sleeping bag after every trip. Here’s how to reduce wear and tear:
-
Use a sleeping bag liner to keep it clean.
-
Spot clean marks with a damp cloth instead of a full wash.
-
Pair your bag with a sleeping mat for extra protection from dirt.
Always check the care label before washing, and steer clear of bleaching, ironing, or dry-cleaning. Dry-cleaning fluids can be dangerous and may age your sleeping bag prematurely.
Machine washing your sleeping bag
Synthetic sleeping bags can usually handle a machine wash—but handle them with care:
-
Secure zippers and Velcro tabs to avoid snagging.
-
Use a heavy-duty front loader set to a gentle cycle.
-
Set the machine to a warm wash (up to 30°C) and add a pure, mild soap, detergent, or Granger’s Performance Wash.
Handwashing your sleeping bag
For a gentler approach, handwashing is always an option:
-
Fill your bath with 150 mm of warm water and add your choice of pure, mild soap, detergent, or Granger’s Performance Wash.
-
Submerge your bag and massage the water in with your hands until it’s saturated. Don’t attempt to lift it when it’s waterlogged—it’ll be too heavy!
-
Let it soak for 1–4 hours, depending on how dirty it is.
-
Drain the tub, refill with fresh water, and massage the bag again. Repeat until no suds remain.
-
Press out the water—gently fold the bag and press firmly until most of the moisture is expelled.
Drying your sleeping bag
Drying is where patience pays off:
-
Air-dry first: Lay your bag flat on towels spread over portable clothes racks to drain excess water.
-
Once semi-dry, use a tumble dryer on low heat if needed—but avoid excess heat, which can melt the fabric.
-
Dry in a shaded area to prevent UV degradation. A hot, windy day is ideal for air-drying.
With just a little care, your synthetic sleeping bag can stay fresh and functional for years to come. Ready to hit the trails? Your cozy outdoor companion will thank you!
