I am wondering if people think a bivy is necessary with a tarp. My wife and I prefer the quilt set up bu haven't used it with a tarp. In the past we used a 2.5lb backpacking tent and want to go even lighter with a tarp. What do you think?

I used to not use much more protection than my pad and bag on a few occasions. I quit doing that when I discovered dozens upon dozens of tarantulas a hundred feet away one morning.

...then thare are those forearm long texas centipedes... Whew.

Creepy.

Biologists have published that these don't get much bigger than 10 inches. I beg to differ. Tarantulas, giant creepers, all three american pit vipers, and two very deadly spiders make me wrap it up every night.

Hi Bjorn,
Your question very much depends on the size of tarp, the weather, and I guess what kind of giant insects you have in your area....

If your tarp is absolutely huge, then I guess you could go without a bivy for weather protection. FWIW, I've use a 55" x 110" tarp in the past and it required a bivy for rain protection during storms. My 48" X 96" MLD tarp is pretty tiny and definitely needs a bivy to keep the weather out.

HTH

A friend of mine became deaf in one ear when bitten inside his ear by an insect. I do live in Australia though.

Jesus...I have slept without a bivy under a tarp, but now I'm getting scared...

Anyone have an MLD superlight bivy for sale?? :-)

I usually sleep without the bivy under my tarp, but... foot-long centipedes? Tarantulas? Deafness? Screw that, I'm going with a fully enclosed tent!

In new england, the worst I've had is slugs on my stuff in the morning, so I find the bivy to be not always necessary. However, if I were camping in a windy area, or during peak bug season, I'd definitely want my bivy around.

Slugs are the worst I've ever had (that I know about) also, but have we just gotten lucky? I'm going to have to do some entomological research on New England ecosystems...

Hey Bjorn,

The bivy will protect you and your quilt from any spindrift, condensation, and other potentially wet conditions that can affect your quilts preformance; not to mention the bug insurance they provide. Bivy Sack's also do a great job of blocking winds that change direction throughout the night. If you decide to sleep without the bivy, use it as a ground cover under your tarp. Depending on your height, Oware makes the Dixon Double Bivy, which has plenty of room for 2 hikers 6'+. The Pertex Quantum top is extremly breatheable and does a great job of keeping us dry and warm. At 11 oz that's 5.5 oz per person!

Hmmm, sounds like a lot of horror stories. I've used just a 5'x8 tarp for many years through storms and whatever else for many years. Never had a problem with bugs crawling on (or in) me. The worst problem I've had is with wind and that is usually because I chose a poor site to start with. Using a tarp requires being more selective of where you are going to sleep. I'd say leave behind the bivy. Part of the pleasure of using a tarp is the room you get underneath it. A bivy takes it away.

This is why I can't get away from my hammock. It would be great to just take a tarp and groundsheet but I can't stand the thought of spiders crawling all over me while I sleep. With my hammock and up and away from all of those nasties and I've got plenty of room under the tarp.

My last night out, when I shined my light around camp I could see all of the white glistening dots on the leaf litter. I thought it was dew until I looked closer. It was SPIDER EYES!!!!

That's it. I am never going to leave Colorado :-)

I have never had a problem with bugs sleeping under only a tarp with out any bivy but I have pretty much spent most of my time in Colorado and the Sierra Nevada.

My tarp is 8x10 so it is plenty big to stay dry, even with two people. I am going to get a smaller tarp and go with some kind of bug netting/bivy so that I have more choices in setup/location etc.....

I am doing a thru-hike of the PCT beginning in April. Ray Jardine has a NetTent that attaches to the RayWay Tarp that I think I would purchase for the Oregon and Washington Sections were bugs are typically a problem. I've slept outside with the critters and crawlers so many times I don't worry about them much.

The thing I am really wondering is if people get a lot of rain blowing under their tarp. Anyone using a RayWay Tarp kit?

-Bjorn

100% of the time I camp there is a super bug (spider, mosqito, midges and others) problem no matter what season. 20% of the time we see snakes (pythons to elapids - most people don't die from their bites but you can haemorrhage from every orifice before anti-venene is given). And so I could never understand how anyone could ever sleep without some sort of bug/snake protection. I envied the US for lack of these. Nice to know that at least in some states you share our 'reservations' of an open camp.

I've have made 2 Ray-Way tarps. One I used his design straight from his book. The second one I made I used a catenary cut for the ridgeline but in practice this did pan out well. I saved a little bit on weight but lost a bit of headroom when the side lifters are used. It's a nice design and the "beaks" add a bit of protection when raining. I also bought and made his net-tent. I've only used it once. Works well also but you lose a bit of room.

Chris makes a good point on the benefits of a hammock to eliminate bug problems at night....

Taking it a step further, given that a hammock can be hung in under a minute with no knot strap and tri-glides or buckle devices, there really is no reason to be sitting on the ground at all.... We use our hammocks at lunch and occasional long breaks...The benefits of several days without dirty knees and a dirty butt are much cleaner, healthier, and much more comfortable camp/hike experiance.

That's some major "spin" going on in that last sentence Mr. Jacksrbetter ; ).

No spin.

Jack always discloses his professional affiliation by his avatar, or in his posts.

His preference for hammocks are what got him started in the business.

Hammocks are useless above treeline. Any ground shelter / cover is infinitely more versatile in all situations.

"Hammocks are useless above treeline. Any ground shelter / cover is infinitely more versatile in all situations"

That's a bit of an exageration. I can imagine if the only campsite you could find was steep, with a torrent of water running through it, and tress too close together and no flat ground to pitch a tent, then you might be happy to have a hammock.
