Arc'teryx Rho LTW Beanie Reviews:


As someone who has seen their hairline come and go, this is the perfect solution for daily wear. As a weekly Bic user, my noggin' tends to get a bit chilly. Add in a dash of cool, damp Northwest weather and you can see there's a need. A full wool or fleece beanie is too hot for 24/7 wear and can make one's head itchy.
This solves all my problems. The material is a little thicker than standard T-shirt material and the texture is about the same; a little softer, since it's merino.
Fits my 7 1/4 head perfectly with a cut similar to the military polar-tec beanies.
Breathable, quickdrying, and just enough insulating power to keep the chill away without overheating your dome. I pretty much wear this all day and overnight from September through April.
It also fits well under thicker beanies and helmets. Works well for bicycling and running or just laying around the house during the rainy season.
My favorite gear purchase this past year.

Neat little hat. I usually wear med/large hats (depending on brand and hat sizing) and many times am frustrated by not being able to find a hat that will cover my ears (I have a nice OR Peruvian Hat...) and this one does just that. I fits perfectly just bellow my ears, and still out of the way of my eyes. I was worried it wouldn't fit when I first saw it, but it is quite stretchy. It makes a great liner for under my other had when really cold or on its own for high output. The fabric is comparable to Icebreaker 200 or a regular cotton t-shirt in thickness. As it is wool it will be less durable than synthetic hats (I was wearing IB 200 wool baselayers over Pat Capilene 2 when I jumped out of my tent, slipped on ice and bashed my knee into the ground, the wool got a tiny tear, the synthetic didn't).

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.

Can't beat this hat for mild-to-cold all year weather. This beanie lives in my commuting pack for wear under a bike helmet and fits nicely into the little pouch in my sleeping bag for a little extra warmth at night. Not necessarily the most stylish - unless wearing a dead bird logo can be considered trendy - but warm and amazingly impervious to on-the-trail stink.
Not the hat I use when on the side of a mountain in sub 20F weather (that one's thicker) but it has its uses - I probably used it every other day from late October to March.
Covers the ears well and doesn't itch at all. The seam around the forehead is small and not noticeable at all (and doesn't leave a dorky seam imprint when I've been wearing it for a while).

i have these in both raisin and coffee bean, surprisingly warm for such a thin material. and it really doesn't itch! it's a tad tight for my head (but I have a big head...wear XL Bern Baker hard hat just to give you a comparison). I love the simplistic yet sophisticated design as it is the case with most Arc'teryx products. since it is a bit tight on my head and there's really no excess material (like the beanies Tanner Hall would wear), I feel a little awkward wearing it for skiing cause my head looks pretty small with my skiing goggles I use it when I'm going to and leaving ski resorts.

Yes this is a lightweight, thin beanie, that is in its name. This has been my exclusive beanie for backcountry skiing for 4 seasons. I use it alone or with an old Backcountry Windstopper softshell beanie as a 3 in 1. With it always stuffed in my touring pack, sometimes worn under a shell beanie, and generally abused. It is not coming apart and hardly shows sign of wear.
It seems to keep my head just perfectly warm while hiking. Like all Merino products, It breathes well and seems to be much warmer then synthetic materials. It will be in my touring pack for many more years.

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 love Arc'teryx, I love merino, and I love the color Deep Dusk, but I couldn't keep this. It's light, flexible, non-itchy, versatile, but the six-dart construction makes it look like a half-a$$ed jester's hat, or, if it's pulled snug , as if I had six nipples protuding from my head. I just couldn't get past that and returned the hat. I much prefer the Vestigio, which has a simple bowl shape and is about as soft, despite having a different texture.

This beanie is great for under a helmet or for light warmth, but don't ask it to do more, it is after all, a light-weight beanie! Works great for a layer piece under a heavier hat as well. Can't beat Merino either -- stuffs tiny and easily into any pants or jacket pocket or nook on a pack.Cons: looks like a goofy swim-cap when worn alone, imo, and others, based on what I've heard. :P This how I prefer to sport it.

Matt Mio at on 03/31/2010

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.
