Does this have a rainfly???

Does your mesh bivy offer rain protection?

Does this bivy have a rain fly available for purchase?

The Mesh Bivy does not have a rain fly. If you would like a waterproof option, search above for our Home Alone Bivy. The Eos is a one person tent with the option of a fly, but slightly heavier.

Give it a fly and it's the best one-person tent in existence. Otherwise, it's worthless, unless you like sleeping in 3 inches of water.

Add a fly and just like any other tent, your soaking the inside of the tent before you ever get the fly on.

This design is ideal because you get the bug protection, breathability, and moisture protection from the ground. For the same weight (7oz), you should add an UL tarp. This would provide protection from the elements as you set up your bivy. Not to mention the added space for cooking, air circulation so condensation does not build up (always a problem) and the freedom to truly adjust it as you see fit.

Worthless, is not a word I'd use to describe it. It is made for a specific purpose... shelter from bugs and other crawlys, with minimal weight and setup. And it does that exceptionally well. I have had it on a number of trips since I got it last year, and love it. You just have to be really sure that you are going to have dry weather.

It is super-light, and I can set it up in under five minutes.

Marmot: Thanks for your response. The Eos was a little heavier. Nothing in life is perfect, but a tent roughly half way between the Eos and the Mesh Bivy, well....... Thanks again

This is a great bivy for what it is designed for. I live in Arizona and do quite a bit of desert backpacking. Rain is no concern of mine but scorpions are. I always just slept on my Therm-a-Rest and my Atom bag until I got stung 3 times by a bark scorpion early one morning and had a pretty bad reaction. That's when I knew I needed some sort of barrier between me and those little guys. The Mesh Bivy is perfect protection from all the creepy crawlies out there but obviously not weather - that's NOT what it is designed for. If you need weather protection, go for the Home Alone Bivy. I've spent a few nights in that pack up in Washington and it performed like a champ.

I am impressed on how light this is and it looks worth 100$. I am looking forward to buying this for my next backpacking trip.

is this bivy free-standing or does it have to be staked down?

Looks like the perfect accompaniment to a 7oz silnylon tarp for max flexibility. Use this alone on clear nights to keep the bugs away, or in trail huts to keep the mice off you. Pitch a lightweight tarp over it if rain is in the forecast. Total shelter weight - 1lb 11 oz

I've camped all over with a rainfly equipped hooped bivy (Solitaire - heavier and harder to pitch...) and much prefer this in concert with a tarp or a floorless pyramid ultralight such as the one I have from another maker. A rainfly'd bivy is a boring place to be in a long rainstorm, while a tarp or pyramid can be roomy enough to get more done in, while the mesh bivy awaits to keep your backside dry and your face bug free when you're ready to turn in. I have not tested in rain, but I expect good bathtub floor performance from it judging by the workmanship.

The foot area can use a tree or other staking point like a hiking pole, but the bivy stands and functions well without staking the foot area, making this bivy useful with my silnylon pyramid tent. With a sleeping bag, draping the mesh on the feet is no problem.

Add to that the impressively high quality of the poles, material, stitching, and stakes, and it's a good deal as part of a modular ultralightweight system.

One question-- the short length of aluminum that is included with the bivy-- what is its intended use?

The short piece of aluminum pole included with your tent can be slid over a broken or bent tent pole to help keep its rigid shape and get you through your camping trip til you get home and replace it.

Is the bottom coated so that it is waterproof? I think this would work great with a tarp if the bottom is waterproof. I live in Alaska; some of the places I go are so darned buggy you'd go nuts if you don't have a way to keep them at bay. This looks like it would be great! The mesh Bivy and a tarp would be a lot lighter than a full blown tent.

I would like to know what type of mesh it is. I often spend time in the northern tundra area during summertime and the very small moquiotos that live there go trough an ordinary mosquitonet. So, do yopu have any numbers on how many holes per squareinch or similar.

Best regards,
Erik

I used this bivy extensively in the Grand Canyon during the summer months. Worked perfectly to keep the numerous mosquito's at bay. I used it in conjunction with a 7 oz poncho-tarp. It only rained heavily once. This allowed me to keep my shelter weight under 2lbs. This was great as I was trying to keep my pack weight low during extremely high heat weather. Thanks Marmot!

I purchased one of these last year, and am very happy with it. On trips where I know that the weather will be dry, it gives great protection against pesky little critters that make your trip less than fun. It sets up in about two minutes, and packs back up just as quickly.

If it's likely to rain on a trip, then I take a full tent. But for good weather, this is my go to shelter.
