that attaches to the saddle and seatpost for bivvying adventures?
Carradice longflap camper
http://www.carradice.co.uk/index.php?page_id=product&under=type&product_id=35
I've got a 2.7 litre Ortlieb, simple, robust and holds a pair of lightweight trousers, a merino top and a pair of flip flops.
Obviously not big enough for full bivvy kit, but pretty useful nonetheless.
The problem with the caradice sadlebags is the shape makes it awkward for getting of the back of the sadle if your decending anything steep, and of course they are a bit on the heavy side, but if your just ecpecting to be sticking to tracks and fireroads worth considering.
I am using one of the ortleb ones at the mament but still a little on the small side, saving up for one from revelate or carousel.
It doesn't get much better than this...

Not cheap though, and a long waiting list!
forgot to mention - I plan to carry a rucksack as well.
Thank so far.
I modified an 8 litre Alpkit Xtra drybag. Wasn't hard.
I just bought some webbing off ebay and played about until I thought it was safe.
The loops on the side of the drybag meant I didn't have to sew anything to the drybag itself. Just made a sling out of webbing.
The hardest part is making the seatpost end of it not too wide so it doesn't catch your thighs. You can do this by packing carefully or I put a spacer between the seatpost and the bag.
Another option is to just get any drybag, buy a rear mudguard (there were some in poundland the other day) and put a couple of straps around the guard (punch some holes), drybag and saddle rails.
One day I'll be afford to buy a fantastic Revelate/Epic/Carousel bag, but in the meantime it's gypsy for me!
With the mudguard thing - I meant mount the mudguard upside down so it holds the pack.
hmm interesting bodge there Alex. Sounds good.
I have a Carradice Longflap Nelson. Brilliant. If you are going to fill it and take it off road you need a bag support, but otherwise its ace.
look in my post on the nuit du bivy thread

its just a bagman expedition that i use for my caradice longflap camper with a dry bag on it - could use a much bigger bag if i wanted tbh - i can get over the back of the bike with it in place.
