Stretchy sun protection and breathable performance in the Astroman Sun Hoodie
What Our Gearhead® Experts Are Saying:
"This is one of my favorite sun hoodies for long, sunny days on rock. It breathes well, stretches when I’m reaching high, and the hood actually stays put under a helmet. Whether I’m guiding or projecting, I wear it nonstop when UV’s in the forecast."
When we’re out climbing, hiking, or moving fast under direct sun, the Outdoor Research Astroman Sun Hoodie keeps us cool, covered, and comfortable. Designed with input from professional climbing guides, this piece balances stretch, airflow, and sun protection so we can stay focused when the day heats up.
The lightweight fabric blends nylon and spandex for a soft, stretchy feel that moves with us on technical terrain. Built-in UPF 30+ protection blocks harsh rays, while the low-profile hood fits easily under a helmet or pairs with a hat. Whether we’re linking pitches or crossing open alpine zones, this hoodie is one layer we don’t leave behind.

Super Rad
Love the colors and how comfortable this sun hoodie is. Have hiked & kayaked in it and the hood kept me nice and shaded while staying cool. Will definitely be buying more when new colors are available!

Nice "Summer Jacket" or Shoulder season jacket
I wear this when its a shoulder season piece or just something to keep me cooler in the sun. It works really well. Its nice and airy and light. In my opinion, this version is better than the newer one. This item is great for anyone who wants something to keep them nice and cool in the sun. Works well as a layering piece in my regular size.

The best sun shirt, period.
This thing is incredibly lightweight compared to other similar sun shirts. I can wear this as a base layer when hiking, a shirt on the beach or on the e water, and anything in between. I only wish it came in more colors.

Does the job
It works but seems a little baggy around the wrists and arms. I have a large and will try a med next time (510/180).

The best Sun Hoodie Money can buy
This sun hoody is one of my favorite pieces of gear- I have 3 that I rotate. They are lightweight, wick moisture, and block the wind (to an extent) that makes the sun hoody quite comfortable. It is a good size/thickness that does not feel warm or snug on the body- I've warn this in 105+ degree heat, and was glad I had it on. I wish it was a bit more durable, but it's durability is already better than other sun hoodies.

Nice hoodie for sunny/hot conditions
- Familiarity:
- I've used it several times
I like the fabric, keeps me cool and dry in hot summer days. Zipper is great for controlling body heat when active. Overall very glad I bought it. Odor control underperforms compared to some of my other gear.

Almost Great
I absolutely love OR's Astroman fabric. It is thin and light, and doesn't retain too much water when I sweat. The fabric is tightly woven (I think... didn't look like a knit to me) and provides solid bug protection as well. It doesn't breath as well as some other fabrics, but that's a known trade off (bug protection vs breathability). The half zip provides nice mechanical ventilation which makes up for a bit of the lack of breathability of the material. I only have two complaints about this product: 1- The material is prone to snags / pilling. The good news- is this flaw appears to be mostly cosmetic in nature and the material itself is pretty durable - but if you aren't planning on using this in the backcountry and you care about cosmetics- it could be a bummer and is worth mentioning. 2- I don't like the wrist cuffs. The elastic is a little tight which restricts air movement (would be less of an issue if the fabric was more breathable). Also- the thumb loop is just a piece of elastic sewn into the cuff - not particularly comfortable and doesn't really keep the fabric over much of your hands if you are looking for sun protection there. If it wasn't for the wrist cuffs I would have given this hoodie 5 stars - I personally don't care if the material snags / pills since I bought it with the intent of using it primarily on backpacking trips. Since I love the fabric so much I just ordered the Astroman long-sleeved button up. I think the button cuffs on it will do much better for ventilation. The only down side is no hood. I'd love to see OR put a hood on something full zip or button or fix the wrist cuffs on this.

New fav
New favorite sun hoodie. The material is light, unrestrictive, and durable. I ordered a size up to accommodate my build, which provided a more relaxed, less technical fit for coastal use. The zip neck is a welcome addition, allowing for increased ventilation. Couldn't be more pleased.
