Borah bug bivy on 03/12/2013 09:52:47 MDT Print View

I'm looking at bug bivies for use with the TrailStar and the borah bug bivy looks like a good blend between function, reputation, and price. What I can't determine from the vast internet is how much (if any) of a bathtub floor it has. Does anyone have one and can provide insight? I've tried emailing borah directly about some other items and haven't received any response.

I have a Trailstar and the single mid-style bug nets work nicely under them. Check out the Six Moon Designs Serenity Net Tent. It's not the Borah you're asking about, but something to consider.

I just received my new Borah bug bivy a few days ago. It doesn't have a bathtub floor at all, just a flat silnylon floor and a flat mesh top. But since the purpose is to keep bugs out of my bed, it seems like that's all that is necessary. If I expect rain or soggy ground I plan to try a plastic groundsheet that can be pulled up on the sides. This is the first time I have used a bivy so l'll be experimenting!

MLD eVent\Cuben Soul Bivy 11.7 ozs on 04/19/2013 08:37:16 MDT Print View


About 8 months ago I was looking to buy a bivy without having ever used one. Like you I was looking for multifunctionality. For me that meant: breathable for winter use in -25C\-13F under a tarp; waterproof for independent (no tarp) 3 season use; and optimum durability\weight ratio.

I hike backcountry in Labrador, Canada, which is very buggy in summer and damn cold in winter.

After extensive research and talking to friends who use bivies, I went with the MLD eVent Soul. Very pricey. Cost me almost $400 once shipping and Canadian custom duties were paid.

It is an awesome piece of equipment, incredibly well made. BUT . . . I didn't know what I needed.

When it came time to use it , I found myself wanting to carry a tarp because a bivy in the rain is only useful for lying down and staying still. Unless your hiking style is hike to dark and sleep, without down time, it offers no\little rain shelter during the couple of hours between finishing supper and going to sleep. Taking a tarp defeats the purpose of a bivy for me - I may as well take my tent.

During the winter my tarp\tent, exped UL7 Downmat, WM sleeping bag and EE Revelation quilt keep we warm and dry without the need for a bivy.

I have never used this bivy. It is brand new. I started seam sealing it and finished one side with seam grip. If you want to buy it, PM me. I will even finish the seam sealing.

Its not the right piece of gear for me but may be for you.

Just made a new bivy, cost, about 10 dollars on 04/19/2013 10:24:31 MDT Print View

Made a new bivy using Tyvek home wrap, nylon mesh, and velcro yesterday. Took a piece of tyvek, cut it to size and dimensions (feet narrower etc), folded it up on the feet end to about where my shins are, taped it closed. Then sewed some nylon mesh to that end and to one side, then sewed some velcro to the other side of the tyvek and mesh. Sewed a loop on the mesh for a tie out point. Weight of the bivy is 11.4 oz. It's more of a bug bivy all in all. As mentioned it cost about 10 dollars in materials. Going to try it out this weekend at Shenandoah N.P.

I plan to use it with my Sea to Summit Ultra Sil poncho-tarp when expecting rain. Weight is i think 12 oz, plus weight of cord and AL stakes.

In a little while, i'm upgrading to a Zpacks Cuben Poncho/Tarp that i've requested and Joe agreed to do for a reasonable price. I will combine that with a Sea To Summit NANO pyramid Mosquito Net, which i will sew some cuben and velcro onto.

However, that combo is going into my ultra durable, but lighter, save for later stash. Course i will have to test it out it a few times.

I just finished my summer bivy. It is reversible. basically so that one side is water proof(1.1 sil) with noseeum at the head and the other is all no seeum(.8 oz per sq/yd). It also has a velcro side entry. it weighed 6 oz exactly after trimming it up w/stuff sack. and its pretty big 8ft long. I wanted to make sure it was big enough to fit my sleeping pad, back pack, and other items I might not want wet.

I will be using it with my sil tarp 1 from integral designs it weighs 7 oz with out stakes and tie outs. It will need atleast 6 stakes and 4 tie outs to be usefull though and that will definately add weight.

I promise to those of you that have read me post this 4 times already this wil be my last post about this bivy......Sorry

Hey Josh, it's OK to be excited and enthused about a piece of gear you just made. Nice weights btw.
