Helium Bivy

Good Cold Weather Bivy

Good for cold weather, tested this out on the AT the other weekend and it was good, the pole is a little flimsy and gets annoying trying to keep it up right. Not good for mid weather climates gets really muggy inside and the condensation builds up over time. Overall great product and lightweight will be using this product!

Field tested, field approved

Bought this for my Marine Corps infantry field ops, and it has not disappointed. It’s lightweight and low profile save space in my pack and allow me to bring more operational essential equipment. There’s a small issue with the condensation on a humid night but if you’re in your woobie or a light sleeping bag you won’t feel it and every time I’ve packed it up wet, by the time I’ve unpacked it for the evening it’s been dry. The different zippers for having an accessible mesh bug net or a completely enclosed bivy are money for those hot humid nights or chilly mornings. I compared it to the issued USMC bivys and they’re roughly 1/3 the width and 3/4 the height.

Sweetness

This is the only bivy ive ever used but it was great. The pole helps keep the material off your face when zipped up and bug net is a great touch. I did get extremely closterphobic the first time I zipped in, but thats a me problem and the zippers are easy to find and use. The only thing that could make this bag better is if there was a zipper on the side to take a leak from in the middle of the night, as the shimmy out of the bag and bivy takes some time and effort lol. Used it on a moto camping trip (with great weather luckily) and looking forward to more UL missions with this setup.

snug and dry

great addition to my kit, been using for a month now during overnights in the Alaskan interior. keeps body heat in well, blocks wind and big win, keeps the mosquitoes out!! been in temps down to 40°F now with winds and bouts of heavy rain, has done fantastic so far in both staying warm and dry. packs up small and dosen't take up much room in my pack. getting in and out can be a circus act for a large guy, I'm 6'5" and 260, but once I've wormd my way inside is plenty long I can fully lay out. thus far I've mostly used just my woobie and stay plenty warm, one of the wet cooler nights I added my patrol bag to level up a bit. was great inside. there is some breathing moisture that will build up when fully zipped in. and when it rained hard, I had to unzip a bit to get some fresh air in. otherwise this has been a great addition to by outdoor excursions

horrible experience

Used this bikecamping and it failed miserably. Was soaked during a medium down pour! Would absolutely not recommend!!

Great Bivy

I love this bivy. I would love to see some type air vent on head and foot. You can unzip some on cold nights for some more air, but then you are letting cold air in. Great bivy overall.

Works great

The bivy works great. It is a warranty replacement for my old Advance Bivy. I mostly use the bivy shelter camping or under a tarp or other shelter. I especially use it in cold weather.

Perfect for Military use

Lightweight, easy to setup and use. Very happy with product for Military applications
