I've been a Snugpak fan for a long time now. I use their drysaks in my Bug Out Bag, along with their poncho, and almost my whole sleep system is Snugpak. Plan to switch out my shelter tarp and pillow to Snugpak was well. Maybe check out their hammock shelter, more of their sleeping bags, single bivvy tents and bigger tents. Have the Jungle Bag, the fleece liner, thermalon liner, and now this bivvy to protect them from rain, and I love all of them.Heard a YouTube reviewer describing Snugpak products one time, as their having performed some kind of voodoo magic in their materials. He hit the nail right on the head with that one. They somehow find the lightest, thinnest, most compact materials to use, in a cost effecient manner when it comes to durability/size/weight. And it's almost like they found a way to blurr the lines and limits, and cheat the laws of physics a little. Yes, you can find more durable gear. But it will be much bigger and heavier. The durability given up for portability with this gear is justified by the weight and capacity in your pack that it displaces. And it's made with combat and stealthiness in mind. The ONLY reasons this bivvy isn't getting 5 stars, are as follows...The descritption mentions a down filling. I thought that was a little off-sounding. But there's no filling. It is a very thin material, much like what you would expect a lighter poncho to be. Similar to their patrol poncho. I wouldn't want to roll around on the ground with it. Definitely want some kind of ground cloth or sleeping pad. Even the official Marine Corps bivvvies wear little holes in them from that, though, and cost about 3 or 4 times as much for a new one. Nearly impossible to find a used one without tiny pinprick holes in it. Been there, done that. Now, that being said, and I know the price has been coming down a little as of late, I think the price tag hurts a little. Took me a long time to finally pull the trigger on this, after drooling over it for years. Especially after trying to get a good USMC one a couple times, and failing. Just seems a little pricey, even if the product is amazing as it is. I guess if you want quality, you have to pay for it. Snugpak's always delivered in that department, so I can't complain too much.So, that's my verdict. Some people feel that it's too thin, and won't withstand much abuse. But I think it's a sound tactical maneuver to go with their lighter/thinner materials, and just try to treat it well. Maybe keep a patch kit on hand in case there's a problem. Other than that, I think this is an outstanding bivvy, from an outstanding company, and I will continue to equip my packs with their drysaks, sleep and shelter systems ?
