Bushwalk Australia

I’m about to do some offshore sailing and have been strongly encouraged to use a “Searug” instead of a sleeping bag.
https://www.searug.com.au

Apparently these are all the rage with the Sydney-to-Hobart set.

The Searug’s main claim to fame is that you can go to bed fully wet and it will a) keep you warm, and b) dry you out as you sleep.

I’m wondering if they could also have their place on land, particularly in very wet conditions. They’re probably a bit heavy and bulky for longer distances.

Anyone come across these and/or have any thoughts?

Heavy? They're 1kg. This is not exactly a block of concrete.

If using on land, I would assume they'd be fine at sea-level at most latitudes. However, there doesn't seem to be any temperature rating on the web site you linked (unless I missed it?). So I would guess that it's probably not suitable for really cold camp sites.

They give a stored size of 28x45 cm. That is about 27 litres.

Good pickup. A good down sleeping bag is around 5-10 litres.

It's hard to tell as they give no indication of materials or construction on the website.
But considering the name and the sparse description of the physical properties I'd guess a pile and Pertex construction similar to the Buffalo Systems bags, with perhaps a secondary layer of synthetic fibre.

From Sea Rug
SeaRugs have been designed using three layers of synthetic material.

Each layer has unique properties.

The blue bottom layer lets heat and moisture through​

The middle layer traps body heat keeping you warm​

The orange top layer "breathes" to let moisture out but helps keep heat in

They also go on to say something about using them the wrong way around. But I forget what it was .. it is on there web site, if you care to look.

[b]Yep could be any synthetic

Again could be any synthetic

I could say exactly the same thing about my cheap Coleman sleeping bag and while it would be true it provides no real information.
I prefer real data not adverspeak

I've used a SeaRug while sailing but I wouldn't use it anywhere really cold. Boats are quite warm in comparison although most sailors will claim otherwise.

For bushwalking, a synthetic quilt like the Big Agnes Kings Canyon is less than half the weight and would probably be warmer when you're wet:
