In reply to UKC Gear: I recently bought the Speed 30 and although I have only used it for two days I really like it... Although it carries the same name it is really a completely new sac.
The main pack fabric is burlier and it sports a much better lid/pocket... The base is much tougher and you also get a snow skirt and roll top closure which works well when the lid is left at base or carried... It also carries weight better too which is due to a reworked carrying system (reActiv)...
It's strippable too... If you have leash less tools the tool holster system works well(as it does with trad tools)
You get a really good Scottish/Alpine pack for £109.99...
Hope this helps
