Well, I have a kind of a sun allergy, so I have now bought two of these from different sellers. This one has a hood, and it's just a weird hood-construction. Like, the hood is on the outside of the collar part, but it doesn't tuck into the collar, so it's just awkward feeling, and it's a bit of a small hood- which is GREAT for people who are biking or hiking- it would be a perfect fit, for you- but I was hoping the hood would be a little bigger/ spacious for my purposes. I just need it to cover more of my face, in the front at the top. But that's not too terribly bad. Overall, it is a great little backup jacket, for extra bright days, and I haven't had any rashes while wearing it, yet, AND I haven't had swelling from feeling hot while wearing it- it's really VERY lightweight, and is somewhat see through. It's not something you can expect to wear for any fashion purposes. It's not fashion forward, but it's good enough for people like me, who have chronic spontaneous urticaria, and people who may have mast cell activation disorders. It zips up, and has a pocket, again- just a weird construction, but whatever. It serves its purpose. I also like that it fits into this tiny little bag, so easily. The bag has a drawstring, which is also nice. I can tie it to my purse, and it doesn't feel bulkier or heavier. It's comforting to have a little spare (even if it's somewhat ugly and awkward) jacket for extra bright sunny days that actually has that high UPF factor. Thanks for giving me a product I can count on at such a good price.I purchased this ultra light jacket for mild cycling weather for arm protection from the sun. I have a UV meter and on a clear day in the afternoon the sun was radiating a 7-HIGH-170 micromols of UV. I put the meter inside the jacket sleeve-one layer between the sun- and it then read 1-LOW-25 micromols. This is around 90% effective UV reduction on my skin so I am pleased as this exceeds my expectations. As a cyclist, the hood will be very welcome under my helmet for additional top of head and neck protection.However, I only gave 4 stars because I've already had the main zipper malfunction and get jammed, the zipper is very light and thin so care must be taken not to break it with more force than needed. The zipper is still working normally after unjamming it using bar soap as a lubricant. Overall the material and construction are very good. As a windbreaker it is about 50% effective as is still allows some air through the material and on a cooler day I can feel it on my arms. A long sleeve T shirt under this jacket would make it a much better windjacket. Overall I'm happy knowing this jacket will protect me from further sun damage.Cooler on than off in the direct sun. Glad there is something out there for people who have skin reaction to sun.Bought for my boyfriend, but kept for myself. I burn easily, so always looking for lightweight UV protection. This keeps me burn-free on sunny hikes, so don’t have to lather up in greasy smelly sunscreen. Also, very lightweight. Though it would be hot, cause synthetic fabric, but not the case at all. Also great as light windbreaker. Can’t recommend as rain protection. It is rain resistant, but no rain proof. Ok I’m light drizzle, but not for downpour.To be fair, I tried this in several intense rain storms, it is not made for a downpour. It may be fine for a light rain, and it is really sold as a sun protection jacket. In a light rain, water will literally roll off the surface. The zipper is very light weight and comes off the track easily, also pretty easy to correct. After reading the size comments from others, I went with standard large, I wear a 'large' t shirt. Order one size up, XL would have been a better fit for me.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. :)The jacket is lightweight and comfortable. I don't like the hoodie as it doesn't cover you face. It's practical but not very attractive. More of dudes style.I orderd the 2XL was too small.. I gived it to my Son. He is a med size. the quality is a great product but there size discription is 3 sizes off.
