Sun screen what?

Great hat for blocking the sun on kayak trips, Vegas pool parties, or just a casual hike. Brim not too big like some other hats.

Exactly what I wanted

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Height: 5' 9"
    Weight: 150 lbs

I was looking for a hat that was cheap and wouldn't make me look like a goofball. My head is 58cm in circumference and I bought the Large size. It is great with some extra room for my buff on hot days. The cinch cord is great to get a tight fit and the chin cord ensures i wont lose the hat in a gust of wind! But just in case you do, it does float on water!

Pretty cool and everyone likes it

  • Familiarity: I've used it several times
  • Fit: True to size

I like it. My adult sons who keep taking it from me like it. It's comfortable and shades everything that needs shade.

Goes with me everywhere

  • Familiarity: I've put it through the wringer
  • Fit: True to size

I've had this hat for years and it goes with me everywhere. I'm bald but the UPF 50 rating has never let me down and I've been in many sunny places for extended hikes and stays. It's been thoroughly used and abused. When I come home, I just untie the neck strap and throw it in the washer. It still looks pretty much new.

The brim does not have a wire in it so you can just squish it into a backpack and it'll recover fine.

I do feel the "OR" logo in the front is about too much. It's large and very visible on the sand color I have. I'd prefer something more subtle.

Amazing Hat for Sun or Rain

  • Familiarity: I've put it through the wringer

I take this hat on all my outdoor adventures from spring to fall. Light weight and great performance as expected from OR.

Works well in the rain too!

  • Familiarity: I've put it through the wringer

This type of hat isn't my usual style but I felt I needed something that would provide more sun protection than my normal ball cap. I ended up using this more in the rain than in the sun (ha!), but wow was it good! I wore it under my rain jacket hood but the front part of the brim protruded from the hood and did a great job of directing the water away from my face. The material beads up water and doesn't soak through over periods of torrential rain. It dries quickly and retains the brim shape well even after being folded up.

Not too keen on the style but I would recommend it for practical purposes if you are in the market for this type of hat - it works for both the sun and rain.

I love this hat. Dry fast, fits great, breaths well and is easy to pack without damaging the shape. It's my go to hat and I'm not going back.

Perfect Hat

  • Gender: Male
  • Familiarity: I've put it through the wringer
  • Fit: True to size

I first ordered the OR Sombriolet, but returned it. The brim was just too big and the style not quite right for me. I got the Helios instead and couldn't be happier. After spending a week in this hat camping, hiking and fishing, well, it's perfect for me. I ditched the chin strap, but could see using it if boating or in high wind conditions. The adjustable tension has been just right for fine-tuning the fit for different conditions. The brim has been good for sun and for shedding rain, like when breaking camp in a downpour. So glad I got this hat!

Can't get it away from my Husband.

  • Familiarity: I gave it as a gift but have feedback to share
  • Fit: True to size

Got this hat for my husband and now he does not want to take it off. Other guys keep stopping him and asking where he got it, which in turn makes him preen like a pretty blonde on prom night. Love the hat, but a little iffy on the diva attitude it has caused.

Superb Hat for all outdoor applications

  • Familiarity: I've put it through the wringer
  • Fit: True to size

This hat is wonderful. It fits and performs better than most every similar hat I have tried, even by the same company. The material is good for hot days even and does a good job of keeping the sun off your face and keeping you cool. I use it for hiking, biking, camping, fishing. Get it wet, get it dirty, get it windy, scorch it in the sun.... it can handle it all.

Nice sun hat

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

Got this hat recently and it really does the job when out in bright sunlight. Sure it's not waterproof and a little floppy but it has a nice wide brim and covers your shoulders and neck well. I would recommend it for nice sunny days, not for extreme weather though.

Summer Hat of Choice!

Every member of our survey crew and family owns this hat. Guys and girls. It's a great light weight hat. Drawstring in the back allows a perfect custom fit. Easy to fold and pack. We have had these hats for years. We have backups for when they are dirty or briefly misplaced. Easy to wash in washing machine, air dries over night. My husband says "you should be born with them on." They have a floppy brim that takes good shape and form after a few washes.

Great Hat

Bought this hat for glider club operations. Fits great, is very comfortable, and shields my face and neck adequately and the brim is not too wear when piloting the glider.

I need a large Kid size age 5,6,7 with this style of hat, color sand, do you have it?? Item: ODR0223

Hi nla5644521,

if you go here:

And you use the drop down button on the upper left side, you'll see that the color Sandstone is out of stock in the Large size--the typical size for a 5,6,7 kid...

If you'd like to know when it'll be back in stock, try using the "Chat" function on backcountry's website--they handle stock issues better than these question forums do (the people answering questions are typically not backcountry employee's).

No more red ears

I absolutely love the OR Helios Hat. It fits perfectly, sheds water well enough to use in the rain, and keeps me from having to lather my dome in sunscreen. I was right in between sizes and decided to go a size up. So glad I did. There is a drawstring closure which allows you to fit the hat perfectly and between this and the chinstrap, this thing will stay on in any kind of weather.

Good details about going up on size. The adjustable drawstring in this hat is great!
