Thanks for responding (hoping you would, as I read in other threads that you were from Ireland).
As this is a business trip, I will most likely be day hiking. However, I would like to try and sneak in some overnights--probably will need to do it next time though.
In a climate like that, do you avoid down gear (sleeping bag, insulating layers) at all costs?
What sort of gear were you using on your 5-day backpacking trip (Do you have a gear list posted somewhere)?
