A couple of friends and I are planning a 3-day trip in the Cairgorms probably in May. Plan is to end up at a B&B each night so no sleeping bags, tents etc will need to be carried - but we will need to lug spare clothes etc...
Given it is the Cairgorms and the weather is not exactly reliable or if we break anything (bike or people!) it could be several hours walk to civilization I am thinking a KISU/Bothy Bag would be worth carrying. Can anyone recommend any that pack particularly small/light?
Then I need something to carry gear in - I am working on the assumption that this will be a small rucksack. It needs to fit camelbag, spare tubes (x2), multitool, small first aid kit, phone, waterproof shell, food (at least 1 days worth), very small pair of non bike shoes for evening, spare clothes for evening in the pub, the bothybag, tesco torch, minimal toiletries, etc...
I am also thinking of getting some sort of Gilet if I can find one that doesn't make me look too camp and cost silly money for a body warmer - the bag will need to fit that too.
I already have a reasonable sized saddle bag and a small camelbag - but I don't think there will be enough space there. So looking for a small day rucksack - probably with the weight low down - but was wondering about something like this Ortileb one: http://www.cyclestore.co.uk/productDetails.asp?productID=7492
Wondering if their are clever ways to pack some of this in the frame - e.g. in a bottle cage?
