Our new ABS rucksacks arrived a few days ago and Laura and I got around to testing them today, they come with a spare gas canister to have a practice with!
I have been thinking about getting either an ABS rucksack or a SnowPulse one for a while and have taken the plunge, they are not cheep but the stats are very impressive. I decided to go with the ABS Vario system and have got a small 15L bag for day skiing and a 40L for hut to hutting, They also do a 25L that looks very good as well.
If you are interested in them I got ours from www.snowsafe.co.uk and you can find out more info there or from the ABS website http://abs-airbag.com/home.php?chid=1&lang=uk&m=17 also feel free to drop me a line if you want to ask any questions.
Now Laura and I are hoping for lots if powder when we go skiing at Christmas!
