I’ve put this thing through the wringer. Recently, i I wore this hoody everyday for 15 days, half of which was spent paddling in Quetico Provincial park and the other half hiking in Olympic national park. It performed gallantly in both settings. Ultimately the shirt met its end after being eaten and regurgitated by a deer in the Olympics, bummed I have to shell out for another now. Qualm 1: kind of a spendy shirt (though worth it in my book). OR is often tough to size for me, I went with a medium on this one, which after breaking it in was the right call. Their Mediums tend to be too tight in the shoulders but just right everywhere else for my 6’2” 195 frame. Regardless, the shirt is awesome, breathes well, resists the stink of repetitive daily use, and has a super functional chest pocket and a deep hood. The ability to unzip the 1/4 zip chest is really great too. My only frustration was occasionally the size of the hood. It’s honestly a big enough hood to get around a climbing helmet, I’m sure by design, but that size hood doesn’t like to stay on a normal head or hat in windy conditions. The addition of a minimalistic draw cord to cinch it down a bit would be nice.
I'll start by saying the material of this hoodie is very different than any other sun hoodie on the market. I'd best describe this as a stretchy thin soft shell jacket. It's not nearly as breathable as their echo hoodies but it's still very comfortable. Another thing that I appreciate is that this hoodie is definitely less dorky than most sun hoodies on the market. The hood itself is also shaped perfect for my noggin, Its very adjustable. With that being said, I'm 5'8 185lbs muscular and a size medium was definitely too small, it's tight around my upper body and when I raise my arms the fabric lifts up to my belly button. I'll be returning it, but I'm not too sure if I'll order a replacement.
Love this piece so far. I'm 6'4", 250lbs and the XL fits me great. I typically need to order XLT shirts but this is sized well for me. Sleeves are good length but wouldn't have minded another inch. Thumb holes would have been nice. I have to maneuver a little to get it over my chest (46 inch) but it's not a problem, just noticeable. The material has a nice stretch to it. Might have a shirt on underneath or nothing under depending on temperature and wind. Love the hood fit with or without a hat. Zipped up the hood stays on well. Zippers work well. I've washed it several times now and the material and color still look new. Washing on delicate and hang dry. I like it so much I might get another.
Wouldn't have any outdoor shirt or base layer without a zippered front to dump heat. The Astroman is about the only sun hoody on the market with this feature. For this reason I already have two and this is my third. Not only is this a great standalone sun hoody but makes a decent wind shirt over a light base layer during the shoulder seasons due to the tight weave of the material. This newer "Air" version has no thumb loops like my old versions so I'm taking one star away. I dont use thumb loops all the time, but it is a nice feature to keep the sun off the back of your hands, and I find myself using them more often especially when the sun is blazing down and I'm not actively using my hands. However, I'm adding that star back due to the updated construction and material in the armpits and down the sides which is a mesh like material to provide greater ventilation for those sweaty regions. Great product!
The sun shirt is super light and breathable. I wore it Canyoneering in Zion at 100 degrees. It helped in the blistering heat while hiking up to shield me from the sun and keep me cool. Then deep in the canyons it felt warm in the cool air. We went through several potholes and it dried out really quick. So impressed I will order for the rest of the family
This sun hoody made it an entire thru hike of the JMT and has no signs of wear even after being worn under a backpack the whole trip. There is minor pilling at the cuffs, but nothing to worry about. The ventilated sides are HUGE in letting a breeze through the jacket - a game changer when the sun gets oppressive at high elevation. The half-zip helps as well. Like most jackets made of this fabric, it does get a little smelly after a few days, and that smell tends to cling pretty hard - par for the course in the world of sun hoodies! I find it dries pretty quickly after a creek rinse.
I really wanted to this sun hoody to work. I tried a medium and a large size. Neither fit correctly. The medium was too short in the arms and torso. The large was correct length in the arms and torso, but it was an absolute balloon around my body. I'm 5'10" and weigh around 170 pounds. The materials feel great and it seems like it would be the absolute bees knees in hot weather, but it just didn't fit.
I picked up the Outdoor Research Men's Astroman Air Sun Hoodie through ExpertVoice a few months ago and it's quickly become one of my go-to pieces for warm-weather outdoor activities. At 5'10" and 160 lbs with a slim build, I ordered a Medium and the fit is spot-on — not too tight, not baggy, with good mobility for everything I do in it.I've worn it hiking, walking the dogs, doing yard work, and even out at the shooting range. The fabric is impressively light and airy, super breathable, and genuinely comfortable even when the temperature climbs. It wicks sweat really well and dries incredibly fast — I've sweat through it multiple times and it doesn't stay wet or heavy for long. So far, no noticeable sweat stains either, which is a nice bonus.The hood is useful for extra sun coverage on my neck and head, and the overall construction feels durable without being stiff. One small thing I've noticed is that the fabric has a slight "swooshy" sound when moving, but it's not loud enough to be annoying. Other than that, it's performed great across all my uses.Highly recommend this hoodie if you're looking for solid UPF sun protection in a lightweight, packable package that actually breathes well in hot conditions. It's held up nicely so far and I expect it to see a lot more miles this summer.
Impressively durable. Pretty much live in this thing. Have climbed in it, taken it into high alpine, daily wear, it’s all around solid. And it looks especially good too. I love the 1/2 chest zip for dumping heat alongside the perforated side panels. And I really like the helmet compatible hood. I think the hoody is good for pretty much anybody in the outdoors. Although it can be a tiny bit scratchy if you aren’t used to having nylon on your skin, but this stiffness goes away after a few washes anyways.
This is not the Astroman fabric of yore...and that's not a good thing. I have multiple Astroman shirts; both long and short sleeved. I love how soft they are and they're comfortable against the skin. This sun hoodie, however, was scratchy and rough-feeling right out of the packaging. Immediate thoughts of sweating under a plastic bag came to my mind. After washing, it's somewhat more supple, but not anywhere near the old fabrics even when new. Does it work? Yes it's highly effective at keeping the sun off. Is it comfortable against the skin? Not to me. I wanted to try this to ward off the sun in warm weather for active hikes or easy runs, but find myself needing a base layer underneath which kinda belabors the point of any breathability. In short...sticking with bamboo sun hoodies.
