I usually don't write reviews for products that I bought on Amazon but I felt like this jacket deserves it :)I was on the hunt for an ultra light rain jacket for backpacking and came across this particular jacket. The description said it was around 200 grams but I thought it should be a little bit lighter for the size that I wear. When I took it out of the box I immediately knew that it's a lot lighter than the specified weight bc I weighed one one my shirts and it's 110 grams and this jacket felt lighter. I instantly took out my kitchen scale and threw in on and "Holly cow" I was shocked when it registered at 69 grams for a size medium, almost too good to be true. I ran the jacket under the facet and all of the water rolled off leaving my hands completely dry. I'll sum up some of the points I like and dislike about the jacket.Pros:-ultralight 69 grams for size medium.-3 grams for the stuff sack.-water proof (to a certain degree)-Has a hidden hood that rolled into the collars and provides insulation for your neck.-slim fit elastic cuffs and helm.-good sewing throughout the jacket.- has a chest pocket to store small items.Cons:-runs a bit small (I am 5'10 and 147lbs pretty athletic shaped, I usually wear size small jackets but this medium fits me perfectly if I wear a one sweatshirts underneath) so size up one size if you're going to wear it over one base layer, and 2 sizes if you'll wear it over a down jacket.-not seam sealed ( though it's pretty easy to do so)-some extra material on the inside of the jacket and stitching on the velcro for the hood could be better.- doesn't provide much warm but this is not what it's intended for.Overall, I highly recommend this jacket if you're un ultralight backpacker and looking to get the absolute lightest rain jacket at the cheapest price point. It left a little bit to be desired but if you take the extra step to seam seal it yourself you'll have an amazing rain jacket that's super light and cheap.Thanks for reading my reviews, I'll update it more if I decide to seam seal my jacket. :)
