Overall, this is a really nice poncho and I can recommend buying it as long as you are aware of the small issues.
Pros:
1. It is extremely lightweight, to the tune of half the weight of a Columbia rain jacket I also own.
2. It packs down very small (About the size of a can of soda. Maybe a bit taller but the same diameter.)
3. It is absolutely waterproof. (Was out in the rain for 5 hours straight and remained bone dry underneath.)
4. The Velcro closures are very strong down the sides
5. The belt was surprisingly useful in keeping it from flapping around in the rain.
6. The tie offs that make it a tarp seem very well anchored and solid (I did not get the chance to use it as a tarp but very much like the fact that it is a possibility)

Cons:
1. The space for your head to pass through is a bit on the small size. (If you have a larger head like me then it will be tight and you will have to take off any glasses you may be wearing)
2. The hood is a bit small as well. (Same issue as the pass through for your head. I had to take off my hat, put on the poncho, then put my hat back on, and squeeze myself into the hood. This is confusing as there is an adjustment system for the hood which will make it smaller, but that feels like it is completely un-needed)

Summary:
I really like it and would recommend it for the many in-built features, but I would also warn that you may find the neck and hood quite tight. If you don't then this is an excellent product.

I just wanted something: lightweight, compactable, light duty for Summer Time hikes ( may stretch it into the Winter). This fits the bill nicely. Don't expect it to be built like a tank, but for what it's intended for, it works.
Summer shade, keep dew off me, occasional shower- it's fine.
Fits easily over a backpack, surprising how many people don't get that?
Great on bicycles, tuck excess between your fanny and the seat, and keep your arms inside the Poncho and grasp the handlebars- keep things out of the spokes etc.
Smells normal to me? I don't know what the problem below is?
For the Summertime I like it.

I was sceptical of the quality as it's so lightweight. I set it up in a few different shelter types, just for fun In the yard. Plow point, lean to, and A frame. It's a tough little poncho. And for the price, a great budget ultralight tarp shelter.

I haven't used it yet. It smells like fish and rubber. And it transferred the odor a little onto something it was laying on. I'm going to wash it and dry it in the sun. It seems to be as advertised otherwise, but I haven't measured or weighed it yet either. I'll update after I wash it. I got the blue one. UPDATE I rinsed and soaked it in hot tap water over night, then dried it in the shade, then aired it out in the sun. Almost all of the smell is gone. I may wash it later with a tech fabric soap.

The hood is *just* big enough for me and I don't have a large head. I had to re-tie the hood adjuster to allow max size. The fabric feels nice and construction seems ok. The dimensions seem about an inch or two short on the long side. Summary; ok poncho if you don't have a large head, a little lacking size for a tarp. And washing is required unless they fix the odor issue.

There is a reason that ex-military survivalists say that a poncho always goes with them. Of course, the ones they are generally speaking of are the heavy military variety, and whether you need that or something lightweight that packs small is a personal choice, depending upon your use. As for me, this sil-nylon poncho is exactly what I needed.

I was going to upload photos showing the versatility of this poncho, but I had forgotten how well-done the sales page is. There is really nothing I can add to the photos and video there except my own observations and experience. What you see in the photos and video is exactly what you will get. The poncho is well-made and very lightweight for its size, and for something made from sil-nylon, the price is very good.

I would like to remark about the guy who claimed you have to be small to use this. Either he got something different from what I received, or he must be the size of Andre the Giant. I am over 200 lbs and wear a large hat size, and I have plenty of room. One very important thing is that there is an excess of material at the neck area so that you can easily turn your head to both sides with the poncho tightened around your face, or with a hat on.

The only thing I would prefer to be different is that the "stuff sack" is not really a stuff sack but a "fold it and roll it up as tight as you can before putting it in" sack. Once you get the poncho out, it is never going back into that sack, in my opinion. Camping companies like to do that to show how small the item can pack, and I understand that, but nobody is going to do what you have to do to get it back into that sack, IMHO. So I would prefer a larger (real) stuff sack that I could actually stuff the poncho back into without a lot of effort.

The weight of the item without the "stuff sack" is 258g or 9.1 oz. Add to that the weight of whatever you decide to use to keep it in. I am using a gallon zipper bag. There is plenty of room to stuff it in there, and I can then squeeze the air out to make a small, flat package.

There is one other use that I can see possible for hammock campers. I haven't tried it yet, but I believe that you could use the poncho as a wind-breaker for your hammock or as an underquilt protector. Just a thought.

This poncho is going with me on every camping trip. Certainly for car camping, but it is also small enough and light enough for backpacking, as well.

So, all in all, great job, OneWind! Well worth the price and 5 stars.
