Hey guys currently running a old huntec bivvy bag and find it doesn't do much for insulation and mostur control, it also lacks in room with my blowup mattress in it,
Would one of the old type goretex bivvy bags be much better and how do they go in the cold 800 loft sleeping bag - 5 or colder etc
Cheers team
Moisture control is good. They breathe really well even if zipped right up. It’s effectively a goretex shell with netting and a zip.
You will easily fit any pad inside the bivy.
The bivy itself won’t insulate much but it will take away any draft and protect from condensation etc.
Plenty of soldiers have suffered through winters in Tekapo using 600loft bags.
I would suggest a quality sleeping bag liner as well. Imo they make a huge difference in comfort in both summer and winter.
Yea they good
I've had mine for 15+ years and it still works fine...I think you'll find they are not gortex but are actually made from" reflex" a similar product.
I’ve got the old gore-tex bivy had it for 20+ years, used it a couple of times this roar gone away from base camp as a lightweight overnighter. Used it in the snow orn tahr trips and do need a good sleeping bag for winter. A mate has a Rab bivy bag and he has way more condensation than my gore-tex bivy. Don’t use it as much as I like as my Hungarian Vizsla doesn’t like the wind and cold and much prefers a tent.
Most ex NZ army bivvy bags are made of reflex. They are a great design, lovely and roomy, insect screen etc but the reflex material itself is not renown for being very waterproof. Fine for under a fly/tent etc, but directly out in the elements they wont keep you completely dry.
We had gortex wet weathers for maybe a year or so in the mid 90's, and they were fantastic but it was too expensive for the bean counters, and the rest as they say is history. Davey Hughs' book covers the grief he had trying to make wet weathers on contract with the Army supplied inferior fabric.
Don't know what material the NZDF are using today, I just know that my British Army issue goretex bag still works fine. Goretex really still is the gold standard.
All the wet weathers I had both early and mid 2000 dpm models and bivy bags are all labelled goretex. Maybe they changed fabric when they changed to digital snow camouflage.
I joined 2012 and my bivy is gortex. Still goes good. Though if there's rain on the forecast I opt for a tent.
Interesting.Quote:

Still looking for one, cheers guys
P m me mate
Dragging up a dead thread, anyone know where I can grab one of these Bivvy bags in good condition?
Yea i've got the gortex model and can't fault it. I remember one night on the open high hills in Waiouru a massive storm hit and the tarp just would not take it. Pulled the tarp down around 0200 and just slept in the gortex bag. It was so much quieter than the tarp (even with the rain hitting it) and stayed completely dry - and this was chucking it down and blowing a gale. Never could fit the issued foam mat together with the sleeping bag inside though even though i cut it down to 3/4 and took some off the sides. I always opted to protect the bag rather than the foam mat anyway, so it never bothered me.
Army surplus is the only place I can think of other than maybe TM.Quote:

Chuck a fly up over your bivy and it's pretty fool proof. If hunting I'd use a ground sheet under my sleeping mat to keep it really dry.
just recently updated mine to one of these flash newer jobbies...my old one was also NZ army issue but MUCH MUCH earlier issue,thin waterproof material with domes down the edges,origonally had 3 lilo type matresses that slid into pockets in the base....
sliding a closed cell foam mat inside bivy bag under the inflatable sure helps keep things in place and adds to warmth.
There was some on market place a few weeks back, there is a older one on it at the moment.
Thanks mate, I’m buggered if I can find them on market place though :wtfsmilie:
Mate that's a Viet Nam era sleeping bag cover. I'd offer it up to a museum if I were you:PQuote:

I can't ever remember getting through a night without at least one of them losing pressure. I remember the lilos looking like Norman Gunston's face, all covered in plasters attempting to bung up all the holes in them:omg::XD:
I had a nz army one made by Macpac if I recall correctly. It weighed almost a 1kg. Better off with a light wt tent was my thought or fly and ground sheet.

There it is. My ultralight tent weighs 120 grams more, and you can sit up in it as well as take your wet clothes off before you get into your sleeping bag - plus the dog fits in as well. I wouldn't look at them unless you were given one for free.Quote:
