The Enlightened Equipment Recon Bivy is an ultralight bivy sack with a waterproof bathtub floor and a combination of mesh and breathable water-resistant fabric on the top. The layout of materials makes it very resistant to condensation while also providing splash protection when used under a tarp. It is well-constructed, with lots of attention to design details that make it easy and intuitive to use, roomy, and adaptable.

Types of Bivvies and Their Uses
The category of “bivy” includes three sub-categories:
Water-resistant bivvies have a waterproof bottom and mesh at the head area, but their uppers primarily use water-resistant fabric to add warmth and splash protection to your sleep system when camped under a minimalist shelter. Bug bivvies are primarily made with mesh with a waterproof floor that’s designed to keep you protected from flying, crawling, and biting insects.
The Recon is a hybrid, splitting the difference between a water-resistant bivy and a bug bivy. It has a waterproof floor and is constructed with a headwall, footbox, and sides that are water-resistant, and a face area and wide stripe of mesh running down the center of the torso–more mesh than you normally see on a water-resistant bivy, but less than on a dedicated bug bivy. This mesh stripe makes the bivy significantly less prone to condensation than many water-resistant bivvies. This construction means you can use the Recon in several different scenarios:
- To cowboy camp under the stars on a clear but buggy night
- Under a tarp to protect you from bugs, drafts, and splashback from precipitation
- In a 3-sided shelter to keep bugs and rodents off
Construction Details and Performance
The Recon’s bathtub floor is 5.5” tall, supported by a combination of stake loops and vertical 5” struts at the four corners. Additionally, the shape of the bivy and clearance for your head and feet are created by a vertical headwall and footwall, held upright by adjustable shock cords, with a mitten clip that connects to loops on the underside of your tarp.

While you can just throw the bivy sack down and get into it, using ultralight stakes on the four corners helps keep it in place (and you on your pad) if you move around at night, in addition to giving the bivy more shape as described above.
The long center zip is a welcome detail if you’ve ever tried to use a bivy with a short chest zipper that you have to wriggle into. It also makes it easy to load your sleeping pad and bag and to enter and exit in the night.

The zipper has 2 sliders, so you can position the sliders where you want them for easy access. Inside the bivy, the sliders each have 2” long, semi-rigid rubber zipper pulls that hang down to find them quickly by feel in the dark–just run your finger along the zipper.
Thin shock cord and a mitten hook on both the head end and foot end allow you to connect the bivy to loops on the underside of a tarp for better head and foot clearance. The shock cord is very thin to save weight, so you don’t want to yank on it. On lots of my gear, I’ve started to move cordlocks to the very end of their shock cord (loosen the tension) before storing them, because, over time, the cord lock will “bite” into the shock cord, causing a weak point (especially on the thin stuff) that can lead to breakage. If it does break, I may replace it with thin static cordage with a loop of stouter shockcord between the cord and the mitten hook.

Surprisingly Roomy
Despite the fact that I was using a regular-sized Recon, not the Long-Wide, I was able to fit a 25” wide, 3.35” thick inflatable pad inside, a 3” thick inflatable pillow on top of the pad, and my 30*F quilt inside without a problem. Lying on my back on all of this cushioning, I found that, with the head-end shock-cord pulled tight, my nose just touched the mesh. This was easily remedied by keeping my ball cap on so the brim could push the mesh away from my face. Nonetheless, I didn’t find the top to be a tight fit at all. I was able to be my normal rotisserie-sleeper self in this bivy, with no feelings of claustrophobia. That’s some generous sizing. If you use a thinner pad or pillow or place your pillow on the floor of the bivy above your pad (instead of on top of it), the shock-cord adjustment provides plenty of clearance for your face from the mesh without the need for a hat.
You may notice the dimensions in the Specs at a Glance show that the Recon Bivy tapers from head to foot. My wide pad also tapers, but I flipped it around with the wide end towards the feet to see if a wide rectangular pad would fit, and it does fit fine–it just pushes the bathtub floor out to gain more width.

Recommendation
The Enlightened Equipment Recon Bivy checks all the boxes of what I want out of a bug bivy: lightweight, easy to enter/exit, waterproof floor and splash protection on the sides, lots of ventilation on the top to prevent condensation, adaptability to many different floorless shelters, and generous volume. I expect this bivy to continue to be one of my go-to pieces when I’m not hammocking.
