Borah Gear Side zip bivy vs MLD Superlight bivy vs Katabatic Gear Bristlecone Bivy

I can only comment with personal experience on two of those. I have an 2009 silnylon bottom MLD Superbivy with the halfmoon window that is still in excellent shape and a 2 year old Borah Gear side zip cuben fiber floor bivy with the all head netting that is currently my goto bivy in summer (cooler and lighter). Both are good bivies, but I feel the MLD is better made and it has a bathtube like floor verses just being a top sewn to a bottom. Both work for their intended function. Every product I've bought from MLD, the weight has been spot on. The Borah Gear bivy had some variance from the listed weight. If weight was the same, I'd favor buying MLD as a personal preference. I went with Borah Gear for the last bivy because they were lighter at the time. MLD is better at getting back to your emails, but Borah will eventually respond. You likely wouldn't go wrong with whoever you buy from, it just depends on what you want.

I Use borah gear bug bivies in warmer weather and katabatic bristlecone bivy in colder weather. Love both of them. I also love all of my gear from MLD..but have not used his bivy because I am so set with the others that I currently use. You can't go wrong with either of them..believe me.

Can you define Cold weather. Cold weather in the desert is 20-40's in the winter. I might be using a bivy for a climbing trip in November. We are planning on cowboy camping at the top of this peak/spire at 7,700ft. MLD definitely has solid stuff and I heard so does Katabatic. I have not seen a lot of info on Borah Gear before.

I guess cold weather for me is below 30 actually. I am a furnace.. However…I use my katabatic bivy in to the 40s..depends if it's gonna rain or not also.. I also use a quilt, so it helps with draft and adds a smidgen of warmth to my sleep system.

The first 2 pictures are the Katabatic bristlecone bivy.. The middle one is borah gear bug bivy Ths last one is my custom borah gear duo bug bivy. Again..I am not saying any one is better then the other (MLD included), I am just speaking of what I use and saying that I am happy with these and will continue to use them. Also with both my borah gear bivies I had a custom 2 way zipper installed across the chest and down both sides.

Thanks for the pics, looks beautiful. Where are they taken? The Borah Gear bivy is on Mass drop for $62.99 I think I am going to jump on it.

The first 2 are on the West Rim trail in PA..last October The middle one of bug bivy was a few weeks ago in Harriman State park, NY..on the timp. The picture of the duo bivy was also a few weeks ago at Pine Meadow Lake in Harriman NY. Keep in mind that I am referring to Borah gear BUG bivy. That's what is pictured also. I have never used or seen their regular bivy, but I am sure it is just as good. And hey..that price is right on. You could always sell it if you decide you don't like it or want to try something different.

This is a big issue. You need to figure out what size pad and sleeping bag/quilt you'll be using in order to make sure the bivy is large enough in circumference to accommodate these items without compressing your insulation. The large Katabatic bivy is much larger than the equivalent MLD, although I'm sure MLD can make you a custom size.

I use a torso length pad at the moment and an EE Revelation. It should fit fine in either.

Titanium Goat makes a high quality bivy(s) at a reasonable price point. I went with the TiGoat Bug Net Bivy over the Borah version because it has a higher bathtub floor. I've used both the TiGoat Ptarmigan and MLD SL (both with full head nets) and though both very well made and fully functional, would give the slight edge to MLD. Additionally, Rota Locura makes a very lightweight bivy too.
