Bivvi Bag for Echo 350

[Logical]

I've recently purchased a Highlander echo 350 sleeping bag from amazon for about £30. Has to be said its one of the best bargains i've come across in a while.

Was just wondering if anyone can reccomend a good bivvi bag as the bag itself doesnt have a waterproof shell. I ask so i can use it with a tipi without worrying about it getting wet or damaged.

Ex army goretex off ebay will do you for starters or try Endicotts surplus store.

I have a 350 and tried with a Alpkit Hunka but found the bag too small.

I'm looking at getting an ex army one now.
