Hi all,

I am looking to lighten up a bit more this year, and round out a system that provides options depending on the scenario In the past year I have moved from a TT Moment, to a Hexamid Long enclosed tent( I have also bought a Yama Mountain Gear Cirraform SW but the jury is still out on the end entrance and I will probably be selling this shortly), although they are both amazing pieces of gear, I am thinking that I would like to be lighter still and allow the flexibility of sleeping under the stars or using a tarp in case the weather turns.

A little bit about me, I am 6 ft 5 about 180 and spend most of my time in the Sierras. I am an active side sleeper using a NeoAir Xlite and usually in an EE 30 degree Revelation. I sleep in WM down pants and a Stoic Cardigan when the temps drop.

I am still looking at tarps but trying to nail down a bivy, to protect from dew, bugs and any light rain that may splash under the tarp.

Looking at the Borah Cuben Bivy which at around 4.5 oz seems like a great way to go. I am usually pretty good with site selection, however I would hate to have a missed cone or rock come through the Cuben and create havoc in Neoair land. so I was thinking GG Polycro ground sheet at 1.6 oz for the med size. This will create a final weight around the 6 oz mark.

The Ti Goat Pharmigan is right at 6 oz with the sewn in mesh hood, however seems a bit more robust in material on the bottom and does not seem to require the ground sheet when taking a little care with site selection. resulting in one less thing to keep track of.

I would appreciate any and all feedback on both the gear and my thought process

Thank you in advance

Frequently when I read a trip report where the person used a DWR bivy they mention condensation. i have never seen any reports of condensation in a totally waterproof event bivy. Why not get totally waterproof bivy that would allow you to go without a tarp on occation?

Yes an Event bivy will cost you more and it will weigh more. However when you add the cost of a tarp and the weight of the tarp to the proposed bivy weight and cost you will wind up at about the same weight and cost. You could then make a tarp out of polycro If you end up still wanting a tarp.

In eight case I would get a bivy with a side zipper to make getting into out and out of easier. I would also use a ground sheet to protect the bivy as well as your sleeping pad. I would also consider a roomy bivy such as the Uber bivy. A roomy bivy would make it easier to packing up and changing clothes in inside the bivy easier when it is raining.
