Highlander Hawk Bivi Bag

I'm very happy with my bive bag I'm really looking forward to use it A lot more over the week's and months

Works as expected, zip is a little fiddly to do when inside but it doesnt detract from the overall quality of the bag.

Had this for a couple of years now. Normally have used it under a tarp and never had an issue. Recently took it out for a week long backpacking trip and decided to leave the tarp and test it out. The first night, there was some light rain and the bag got wet on the outside but I was warm and dry inside with no issue so the material is fairly waterproof. The second night, a storm hit and I just managed to get in the bag before the storm hit. I still had my headlight on in the bag sorting out my belongings which was how I was able to watch drops of water leaking through the entire length of the zipper.
I had to squish into a friend's tent with them because I would have been soaked if I stayed in the bivvy bag.
The rain was really coming down but I wouldn't have thought that the zipper would leak just from rain.
I also found it was a bit tighter than my other bivvy bag which was a little uncomfortable in the cold with a bigger sleeping bag but you don't but a bivvy bag because they are spacious.
TLDR: Works well in light rain and wet ground conditions but I had a hard rain come through the zipper so this may not be the best choice if you don't bring a tarp for additional shelter.
