I have base camped and also from an open canadian canoe for a long time where weight was not a problem.  However being the wrong side of 60 I wanted to carry as little as possible.  I have not rushed into new equipment as I was not sure that backpacking would be something I could get on with - it is!

So to make a start I have invested in the following.

1/ A Go-Lite Jam rucksack
2/ My sister in law made me a micro tarp which has been a success - but I have chosen my weather.  I do have a larger tarp which may be utilised.  I now have  a Go-Lite Shangri la 1
3/ An Argos down sleeping bag.  This works with the addition of extra clothing, but will be an area of change in due course. I could not resist a bargain 4 season bag but have yet to use it.
4/ An exped 3/4 sleeping mat. I have now obtained an arrived type which has proved comfortable.
5/ An Alpkit Hunka bivvy bag
6/ A clone Caldera Cone which my canoeing buddy made for me.  This together with a Vargo Titanium mug work well.
7/ I have moved to trail shoes although my Brasher Hillmaster boots are not that heavy.  My latest trail shoes are New Balance picked up for £15.00 in Go Outdoors.  Lots of mesh but when wet, dry quickly and lovely and cool in the heat.  Probably not for the winter. The Brashers now regulated to gardening and a pair of Meindls obtained. I have also obtained a pair of inov 8 boots which have proved to be comfortable.
8/ I bought a Rab Momentum cag which is lightweight and seems bombproof.
9/ Most of my other clothes are from Aldi/Millets or other bargains picked up along the way.
10/ To keep me warm in camp I bought a Rab Generator Phil on - toasty.
