I am 6'4" 385 and fit well. I just used it to sleep out last weekend and it definitely help keep out the strong wind even though it was only 27 deg F. One downside though is if you twist around and don't breath directly out the screen it will condensate...a lot. I had a drops of water all over when i woke up. Not a dealer breaker though. I used it with my mmss sans the gortex shell since i had this and I was very comfortable despite the cold. Review: Ultra-Light, but not 100% water tight - This Bivi-bag is designed for tent usage only. It isn't 100% goretex, just on the upper portion, the bottom is a tafta nylon. Don't get me wrong though this bag is ultra light, tough and large enough to put your belt kit in the upper portion. It however can't be used as a emergency floatation device by putting your rucksack in it and making a life raft. The price being asked for it is about right, but not the orginal asking price unless you have a CAGE credit card LOL ## Features - Nylon ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00TGBVPM6 | | Age Range Description | Adult | | Customer Reviews | 3.9 3.9 out of 5 stars (7) | | Fabric Type | Nylon | | Occupancy | 1 Person | | ShellMaterial | Leather | | Temperature Rating | Comfort | ## Product Details - **Age Range (Description):** Adult - **Fabric Type:** Nylon - **Occupancy:** 1 Person - **Outer Material:** Leather - **Temperature Rating:** Comfort ## Images ![Sierra Designs SFC Assault Bivy - Image 1](https://m.media-amazon.com/images/I/51VoJ1a3qDL.jpg) ![Sierra Designs SFC Assault Bivy - Image 2](https://m.media-amazon.com/images/I/31kgUNIa6PL.jpg) ![Sierra Designs SFC Assault Bivy - Image 3](https://m.media-amazon.com/images/I/410yoNbZWuL.jpg) ![Sierra Designs SFC Assault Bivy - Image 4](https://m.media-amazon.com/images/I/41A7D5DptdL.jpg) ![Sierra Designs SFC Assault Bivy - Image 5](https://m.media-amazon.com/images/I/41kGSOW78kL.jpg) ## Questions & Answers **Q: How big is it once it is compressed inside the stuff sack?** A: Inside the stuff sack, it measures 5" x 16" but with a proper compression sack, I am sure you can take that down to half the size **Q: is this item as seen in the photo or is it in digi camp?** A: it's as seen in photo, one solid color desert tan. Very well made high quality.. **Q: How much does this weigh?** A: 1lb11oz **Q: What is the sleeping bag on the inside of the bivy that is shown? Does it come with it?** A: Per the pictures it appears to be one of their own.... but this is just the Bivy cover - no bag included. I am sure the photos with the bag included are just for illustrative purposes. ## Customer Reviews ### ⭐⭐⭐⭐ Great size and protection but does condensate. *by A***T on January 20, 2016* Very roomy.
