Arc'teryx Rho LTW Beanie

All around great piece of gear for active pursuits. I initially thought I was going to hate it because it's very light and thin. I was wrong. By itself or under a helmet it was a wonderful piece of gear whether AT, snowshoeing, or in the mummy bag. Go heavier for more extreme conditions. It worked excellent in the changing weather conditions of the Sierra Nevada a couple weeks ago.

these are great and can be used in so many different ways--as a wear around cap when not exercising; they are also great under the helmet while skiing or cycling in cold weather. They keep your head warm!

The Rho is a light, breathable standalone cap, and makes an excellent liner for bike, ski, or climbing helmets. You won't get an itchy forehead when you work up a sweat thanks to the merino wool, and the odor-resistance is unparalleled. This was a Christmas gift for my father-in-law, who loves using it for hiking or nordic skiing.

this beanie is great, gave it to my dad for christmas and he wears it for everything. Skiing under his helmet because of the thin profile, and also out to shovel the walks and in the cold evenings. very low key on the design and logo, making it ideal for any occasion.

I bought this thing back in 2015 and have been using it ever since. I usually throw it on whenever it dips below 65 degrees. Even if its a little warm I'll wear it up in the mountains just to keep the sun off my head. Amazing and comfortable material. Fits great under helmets too. Its held up exceptionally well and prob won't ever have to replace it. It's always an essential piece of gear and I take it everywhere i go.

This beanie rocks. Its super thin but really packs the heat and keeps your noggin toasty warm in any kind of weather. It breaths so well I wear it running, hiking and other high output activities and never return home with a soggy hat. Its seriously soft and cozy and I would for sure bring it on a backpacking trip to wear to sleep or under a hat on a cold day. The fit is nice and form fitting and covers my ears without any bulk. I got just the "one size fits all" and it fits my medium-ish size head and it also fits my boyfriends head which is much bigger than mine with a lot of hair so this beanie is pretty versatile as far as sizing. Definitely would recommend to anyone looking to do some high output activity this winter! here's a pic of my bf rocking the skully under his hat before a backcountry skiing mission. We both love this hat!

I use this as a helmet liner or lightweight hat for around town or hiking. Quality made, love it.

I bought this strictly to wear under my snowboarding helmet. It's thin, keeps my head warm, and isn't too itchy. Perfect! Only reason I gave it 4/5 stars is because I don't really like the look--it's sort of like you're wearing a swim cap. That said, it's pretty much what I expected from the photos and description, so if that's the look you're going for, no problem. But for me give it 5 stars I would have to have been pleasantly surprised that I didn't mind wearing it around after I take my helmet off.

Light enough to fit under a helmet. Stretchy enough that it fits comfortably over my over-sized noggin. Warm enough for days when you just need something to keep the cold air off your head

If you have a small-to-medium-sized head and need a technical/active/under-the-helmet beanie, read no further, because this thing is perfect. It's a bit thin and tight, though (my head is 56cm), so it creates an aesthetic I'm not a fan of. I'll be returning it, because I wanted more of an all-around/casual beanie with the Arc logo, but don't let my tale dissuade you; merino makes the ideal beanie material (warm, breathable, non-itchy, antimicrobial, etc.), so grab this thing if you're active and not too large-skulled.

Best hat I own. Serious comfort, covers ears and looks great. Don't over think it, get one.

Good fit, light, mid-warm, merino benefits. I use it under my helmet for skiing/ around town / Trekking. Very versatile and breathable. Can store in a pocket. Easy to forget on your head, it's the best do all beanie. Good for aerobic activities and dry fast. Satisfied guy here!

I just tried this out for the first time. I used it in a strenuous, rainy and windy hike. Under the hood of the rain jacket, it was perfect in keeping me warm but not hot. I never felt the need to take it off unlike what I often experience with a thicker Icebreaker beanie.



Unless you're working out really hard I don't see this beanie being warm enough for cold weather though, but that's very subjective.



Like all Arc'teryx product, it is expensive. I'm not sure I would pay full price for this.

This beanie is perfect for ski / splitboard touring. It's lightweight so your fat (well mine's fat!) head won't sweat buckets breaking trail in bottomless powder.



For colder tours (e.g. this photo!) you'll definitely need a warmer beanie on the way down (if you're not wearing a helmet).



Being super light and thin,it can be stuffed in the smallest pocket. I keep it in my pocket on inbounds days so I can put it on under my helmet when needed.



It's 'merino' style wool, so it doesn't clunk and dries quickly.

I own a bunch of beanies for variety. But since i have purchased this one I don't wear the others nearly as often. I love this beanie because it is light and comfy. I like have a beanie that doesn't cook you if you pop inside for a bit. It is now my favorite.

Good soft hat nice to have under my hood or helmet.

My all time favorite beanie. Wore one 24/7 through months of chemo and rad. Funky use but greta beanie to have. Comfortable and warm with almost zero weight.

Just got one of these little wonders the other day. In love with it already. I'm wearing it at home right now! Can't take it off. Weighs nothing and is far warmer than you'd expect. You barely feel it on your head other than the warmth that it creates. Now you are not going to rely on this in freezing temps but for cool days its the go to piece. If its super cold you can always throw on a thicker beanie over top. What I love most about it is that it folds up so small that you can carry it in your pocket and not look like a dork. I've got a lot of Arc. pieces and I am crazy about them all. You get what you pay for with Arcteryx each and every time.

The best technical beanie I have. Although i would not wear this around town casually, it is a must have for cold weather running, snowshoeing, hiking and backpacking. This tough little bugger absorbs more liquid than a sponge while still keeping that head toasty, and it is lighter than a feather. Don't question it, just get it.
