I didn't bother, find it just as easy to slide in and out, usually use a silk liner anyway so not having a zip on the bag wasn't a problem.... and it just adds extra weight 

I have Alpkit Pipedreams 400 & 600, very good spec when you compare them to other manufacturers, stock is an issue but it's worth getting on their mailing list for updates. They're supposed to moving their production to the UK but I don't think it'll happen this year, once that's in operation though they'll be a force to be reckoned with I should think.

Hi Rich, I went for no zip, and really haven't found it an issue to be honest. I do sleep on the ground mostly though, but have used it with my hammock as well. Regards, Dave
