Water Proofing Your Sleeping Bag

Kristin Hostetter from BackPacker magazine addressed the question “Should I choose a sleeping bag with or without a waterproof laminate? Can you explain the difference?

The most apparent difference will be the price. The additional cost of  a waterproof shell is around 100 bucks. You have to decide if your style of camping really merits the investment.

If you camp bivy-style or sleep under a tarp, the extra weather protection is a huge plus, and worth the investment.

If you’re from a rainy region or if you’ve had problems with your bag getting wet, a waterproof shell fabric will give you some peace of mind.

A DIY solution is to buy a bottle of DWR for about $10 and apply it yourself.  Two good options are  Revivex Spray-On Water Repellent or Nikwax TX Direct Spray-On.  They are easy to apply and although  the DIY approach won’t render your bag totally waterproof it will create a decent barrier to moisture that will shed tent condensation.
