Hi Paddy
the rafts go from around 1.45 kg(3.18 lbs) but limited use I would imagine. Mine above is 2.4 kg (5 lb. 3 oz) and it's useable upto pretty rough white water 3 I believe. Folds down to the size of a 2 man tent, even smaller tbh. The paddle is mostly carbon fibre and a 5 piece, weight 29 oz. (.822 g) doubles up as tarp poles.
They do a range of about 8 rafts, all varying around 1kg difference in weight.
I expect she was carrying about 3-3.5 kg max for her raft.
The ideal weight makes not having to inflate and carry them on your back / drag them to them to get to other bodies of river.
Check out youtube for "roman dial packrafting" and you'll see these things are hard as nails for weight ratio. Roman has done Alaska I do believe in one, the vids should be on there.
The fox, lol, yep sniffed by head one night through the tarp.
Those badgers can be pretty dangerous I heard especially if cornered, got some claws like Wolverine!
cheers !
