World's First Floating Sleeping Bag

No, your eyes don't deceive you, that really is a man floating along a river in a sleeping bag filled with Nikwax's Hydrophobic Down. No Photoshopping or optical illusions, we saw it with our own eyes - honest, guv...

Top water-proofing and fabric care giant Nikwax, produces the fluorocarbon-free, water-resistant Hydrophobic Down now used in various outdoor brand's down-filled clothing and equipment and it rolled out the floating sleeping bag to demonstrate just how effective the treatment is.

Of course no-one's suggesting you use your sleeping bag as a stand-in life raft, but it's reassuring to know that if your tent or bivi bag springs a leak, you should stand a fighting chance of still having a functioning sleeping bag next morning.

How does it work? Here's a video explaining how the Hydrophobic Down is made.

We like hydrophobic down. It's like a sort of safety net that means if your down jacket gets soaked, it doesn't become instantly useless. The video from Go Outdoors above maybe slightly geeky, but it does a good job of explaining how the stuff works and what advantage it has along with some real-life scientific testing of the Nikwax-treated water-resistant down used by Rab in their latest kit.

Well worth sitting through if you're debating the pros and cons of water-resistant down.
