I noticed on this on the Sea To Summit web page last night http://www.seatosummit.com.au/products-page/sleeping-bags/spark-spiii/
I also didn't realise until last night that STS are using Dry Down in their bags too. Has anyone here had any experience with the performance of their Down in damp conditions?
My current sleeping bag is an old, but very trusty One Planet bag. I''d like a new one in the next 12 months. So I'm curious to know whats around so I can watch for sales.
