Mil-Tec Trilaminate Durable Waterproof Lightweight Breathable Tactical Outdoor Camping Hiking Generous Cut Sleeping Bag Cover with Zip Closure | Suitable for Various Sleeping Bags

Waterproof, windproof, and extremely rugged. Like any bivy, it will accumulate condensation if you're sealed up inside it, but proper venting of the zipper will minimize this.The zipper is heavy duty and the bag itself dries rather quickly, even in mid 50° F weather. Zips up very nicely around a standard sized military mummy profile bag.Compresses down very nicely. If you're concerned about the space it takes up, definitely purchase a separate compression sack, as the stuff-sack provided doesn't do much to shrink it down.

Great high quality bivy sack. The material is alikened to the same fabric used in commercial seabag, even lighter; with an interior liner. It should be easy to wash and be highly durable. I am excited to use it.

Solidly built, heavier than expected, and a little bulky. It will take up more space and it weighs more than my lightest tent, so I am not sure it will become my backpacking go-to, but I will use it as an emergency shelter or an extra layer in cold or wet conditions.

The triple layer will roast you lol used outside in 28° weather

The size is large, the material is obviously waterproof... Looks like rubber in the inside. The weight is actually pretty lightweight and it's perfect for a bedroll.One button was broken when I got it but it has a zipper as well and it was probably just a fluke. Still five stars as it's the top button and I probably won't be using it anyway.

I needed to prepare for a winter field exercise, but I'm on a budget so couldn't justify springing for a Gortex BIVY. I went with this. I packed this BIVY, a wool blanket. It worked like a champ. I was quite warm during the below freezing nights. A buddy used one of these with only a wool blanket and Woobie and froze his ***s off while being fully clothed. Was that the right call? I don't know. Some say you should strip down to fill the bag with heat better. Stripping down wasn't really an option for us however.Things to note.The construction is solid. The material is a durable canvas-like material (not cotton) with a water proof layer inside.Be aware the zipper is on the right side. If your sleeping bag zipper isn't also on the fight it's a notable inconvenience.It will collect condensation inside. You'll want to ensure you dry and air it out in the morning before you pack up.I'm 6.1, 215 lbs and fit fine but there is no wiggle room. This means if your arms are out of your bag inside the BIVY they will press against the inside of the bag bringing the cold closer to youStill it's about what I expected from the description and I'll use this BIVY many, many times in the future.

I love Mil-Tec products. Just do! Also Military 1st who sells them! Great store!I want to love this bivy too!! Fabric solid, zipper great, sewing great. Quality equals USGI Bivy hands down. I have both.But......the internal button rows you use to attach your sleeping bag in the 3 piece sleep system have a problem. 3 of the 4 rows of buttons are great. Solid. However the 2 internal rows of buttons you use to to attach it to the Patrol Sleeping , line up perfectly, but one of the two rows the factory in China sewed on, are an entire row of the wrong buttons! I guess they just sewed on what they had available and called it good. But it is not good. They will not attach to the sleeping bag as it is the wrong buttons.I have contacted the Seller to let them know the factory in China sewed on the wrong buttons. The Seller has great customer service, so I will write an update to see if they are able to get the correct buttons from the factory or ship out a new one that the factory in China didn’t mangle.

I was in a slight drizzle for about 3 hours, woke up with a little water intrusion, not enough to soak my sleeping bag but it was not completely dry. For the money I’m slightly disappointed.
