I'm off for a weekend under a tarp (probably in a forest) and I have a Alpkit Hunka. I'm wondering if I'm under the tarp and no rain is getting in do I actually need to get into the bivy bag? It has no zips and seems like it might feel quite restrictive so I don't want to use it unless I have to.
This is one of my set ups,survival bag and bivi bag with thermarest in the bivi and my sleeping bag and tarp above ideal for all weathers ,and the survival bag doesn't make it slippery.Just thought i would share that.
I spent last night up on Dartmoor under a tarp. Laid out my poncho on the floor as a ground sheet, put my sleep mat on top and my sleeping bag on top of that. I had my bivi bag with me but never got in. This morning, my sleeping bag was bone dry (which it wouldn't have been inside my bivi bag) and I had a great, warm, night's sleep.
As has been said above, if conditions demand it, use a bivi bag; if they don't, why bother?

Hey Ocean1975,
Any chance of some details of your tarp please, dimensions and make etc? It looks big enough to be useful but not so huge as to be heavy - nice set-up!

From personal experience, bivi's (mine at least ) do not protect against midges or ticks!
