Took a look at both of these and the Neutrino 400 yesterday, not certain that the 200 is warm enough for spring to autumn UK use but so tempted by the pack size.
i have the 200 (bought for summer use in europe) and will be using it in Scotland in May where it can still get pretty cold at night. Hoping that use of a insulated jacket, silk liner and hat will keep me warm enough...
