I have a bit of a love hate/relationship with Patagonia's fit, but this is one of their items that fits as billed, does more than I asked for and is now a midlayer mainstay out of my closet three months out of the year. I'm 6'2 and 170 and the cut is fitted but loose enough to pull on over a merino wool baselayer. Long with low-profile Polartec Powerstretch fleece below the beltline means it stays tucked in under a shell. Stretchy Polartec fleece throughout means the sleeve cuffs stay at my wrists but easily stretch to make the thumbholes usable. The long front zip vents core heat on command, and the offset at the chin eliminates zipper chafe, but does help to make it a bit goofy looking as casual wear. The scuba hood is superb, perfectly fitted and articulated, with a high collar that provides an instant balaclava when the weather gets nasty. And yes, you will look like a ninja if you get it in black. The Polartec gridded fleece that makes up the body wicks incredibly well, and is super-warm, belying its light weight. Under an uninsulated Gore-Tex shell, I've climbed, hiked, snowshoed, skiied, and boarded and I've never needed any more warmth than I get from this layer, unless I've stopped moving for lunch or get stuck on a lift. The only complaint I have is the price, but ultimately it is actually worth it. Pitch perfect design from Patagonia.

Perfect for a climbing or backcountry action suit. Slim fitting and cut for active activities in cold weather. Hood is designed to fit like a balaclava, thinner weight fleece at the bottom of the torso makes for a cleaner tuck into pants to keep the cold out.

Last of the good R1 pullovers. Patagonia switched up the cut and the cuffs of the R1 about a year ago, and this is the last of the raglan sleeve style R1s with the Capilene 4 at the cuffs and hem. The thumbholes make it so easy to put gloves on without having to hold your cuffs down.

I wear this when I'm skating, and even when it's cold in the rink, I work up a sweat rather quickly. The hood makes it so I don't have to wear a headband, and keeps my face from getting frozen from the rush of cold air. But if I've been racing, opening up the zip all the way cools me off nicely. Fairly durable too, especially when I go sliding across the hard ice at my local rink.

I sleep in mine too when the temp drops. It doesn't ride up, my hands and head stay warm, I don't need to resort to five million blankets.

First, the thumb holes are awesome. Second, the hood with full face coverage acting pretty much like a baclava is ingenious. Third, the long torso length ensures it'll be in nearly every layering system you put together. I'm 6'4 180 and wear a medium perfectly. Hood goes over a climbing helmet (a stretch) or under it. Doesn't block wind, but adds quite a bit of warmth. Chest zipper goes down quite a ways for easy on/off too. Holds up great like all Patagonia products. Also, the pocket is on the right side which is really nice if you're left handed or if you're jacket pocket is on the left side (most are)!

I have 2 R1's and now the R1 hoody, and I honestly rarely where anything else. Whether worn alone or with an ultra-light layer underneath, I can usually wear them for 3 or 4 days before they even start to smell like they need to be washed, and that includes morning runs in these babies. I've abused all these things rock-climbing and ice-climbing, and so far no signs of wear or pilling. My only complaint is that since they don't transfer large amounts of moisture as efficiently as wool, if you overload the wicking capabilities of the fabric, you get that clammy feeling. But since they dry about 100x faster than my icebreaker wool, it's not really a big deal.

I found that they fit true to size (if a bit more of a slim, performance-fit than the original R1 - the "alpine cut" effect). I'm 6 ft, 148 lbs and I fit perfectly into a medium. So yeah, buy 1 of these...or 5...and I can promise you'll end up disregarding the rest of your wardrobe.

This is the best layer availible. I wear this peice while climbing, either by itself or under a softshell/hardshell. It is super warm, and the half zip length allows you to vent any unwanted heat. During hanging belays in chilly weather there is nothing better then poping the hood on under your helmet to cut the cold wind. This peice has earned its way into my pack time and time again

This thing is designed for the top - so don't slow it down. Lightweight, moves freely, hood fits nicely UNDER the helmet, thumb loops keep your sleeves where you want them. A really cool feature is the thinner material around the waist - it means you can layer without compromising the fit of your harness. This is an all year all mountain layering piece that eliminates cumbersome bulk. Washes easily. Pair it up with the patagonia houdini shell for a super light all weather system. Either they fit a bit slim or I'm getting fat.

Wore the "ninja hoodie" while skiing at Alta in Utah. The thing didn't even smell after I wore it for three straight days of skiing. First two days, it snowed non-stop and the zip up hood was perfect for protecting my neck and cheeks and fit perfectly under my ski helmet. The third day was sunny with temps between 25 and 36 degrees all day, and this shirt (along with a t-shirt as a base layer) was all I needed.

It's also a great layer for cycling in chilly weather. I've thrown this thing on over a sweaty jersey after reaching the summit of a few mountains in Colorado in July (when it's windy and at most 40 degrees) and it's stopped me from shivering. The hood fits wonderfully under my bike helmet and protects my ears on the descent down from the summit.

It's warm, comfortable and breathes really well. Have barely taken it off since I got it.

I'm not sure why it is refered to as a jacket because this works best as a shirt. I find the hood provides a great insulation and comfort layer when wearing a hardshell hooded jacket. It also helps to reduce the noise created by your noggin moving around in a hardshell hood. This fits on the smaller side of Patgonia's sizes so you may want to go up a size. I normally wear a large, I have this in a large but it is really tight. I plan on purchasing another one and will get an XL.

Exceptional layering piece. Lightweight fabric isn't bulky but insulates well. The balaclava-style hood is perfect, and I can leave the hat/balaclava/neck gaitor combos out of my pack. The monkey thumbs allow for a lighter, more dextrous pair of gloves. With the hood deployed and zipped, the stretchy/slim fit of this feels like wearing a super hero costume. I wore this in combination with an REI Polarmax tee, Montbell thermawrap vest and rain shell while snowshoeing and xc skiing in the mid-30s with wet snow and 20-30 mph gusts and stayed warm even when not moving. I wore it running with the same combination in -4F and stayed warm. The deep zip allows for all the venting you could want when you heat up. The chest pocket is big enough to hold a map folded in half. I wear the medium (5'10", 170) and it fits spot on. I like the length, as it doesn't expose my waist when bending or stretching. As a previous review noted, paired with a wind shell I'll probably stay warm in anything down to 40 degrees

i own both the hooded and non hooded. they are my go to pullovers.great fit and just warm enough without being bulky. great as a mid layer too because of the off set zipper. TWO THUMBS UP

If I'd bought this 20 yrs ago, I wouldn't have all the other layers I've collected over that time that are now obsolete. For anytime other than summer, this is THE layer you want against your flesh. The comfort is unlike any material I've ever worn, and it does a great job of keeping you warm & dry. The hood is much appreciated for when you need it, and get's out of the way quickly when you don't, without the hastle of having to pack it away somewhere. I'd have no qualms of wearing this for several days straight if backpacking. At 5'-11"/145 lbs, I opted for a small, and it's perfect for me. The hood & neck is snug, but not to the point of being uncomfortable. The one zippered chest pocket is good for keeping a Cliff bar or two from freezing. I may never get used to the off-set zipper up top, but it wouldn't keep me from buying another. Quality is typical of Patagonia - none better.

Just used it to go xc skiing. Wore it as the only layer under a light shell in 20 degree weather. There was no wind and it was clear after the first 20 minutes that it would have been sufficient by itself. The garment is warm and breathes very well. Wonderfully comfortable.

Like another review said, If I had this 10 years ago I wouldn't have a bin full of antiquated and worthless baselayers. The R1 is simply the best. I use it for skiing, hiking, climbing, lounging - the list goes on. It works great as the next-to-skin layer and does not disappoint with superior wicking and insulation properties. The hood is clutch for cold conditions climbing and skiing. Not exaggerating when I say this is my favorite layer for cold weather activities. I'm lanky at 6'2 185 and wear a medium. No problemas aqui - worth every penny.

This is NOT a great townie hoody unless you like wearing purely technical gear for non-technical reasons. It is however the VERY BEST technical hoodie I have ever found other then the Lowe Alpine Ninja Hoodie of old that I suspect this was taken from. The fit is, shall I say, Fitted! the Hood is ninja like and the reason that people tend to break into a ninja pose when they zip this sucker up. the offset zipper at the top makes for a strange lay of the flaps when not fully zipped but like I said its a purely technical piece. Its function is superb. Its warmer then any other hoody I have tried. Cloudveil, and older styled OR.OR now makes one that looks very similar to the R1. I suspect that the local CO OR rep listened to my complaint when I said OR needed one too. I have a medium and I am 6,1. The fit is great but the sleaves could be an inch longer for me when using the thumb holes. I don't think I would like the balk of a Large. The bottom thin fabric is perfect for tucking into pants to stp drafts. A must have

WARM! This thing is super-warm for its weight and bulk (something to do with the weave, I think), the hood is dorky-looking but super functional (especially if you're going to be wearing it under a climbing helmet), the thumb holes are excellent and the change in the thickness in the lower torso makes it great for wearing under a harness.

Definitely my favorite midweight layer. I ice-climb in midweight Capilene, this and a shell, and then keep my down hoody on the harness for belays. So basically it's perfect for intermittent high-output activities in the winter.

The R1 Hoody is a great layer. I love the long fit. It is long enough to stay tucked in all day while skiing and the long sleeves with thumb loops prevents them from riding up. The hood is not bulky and feels good up or down. In fact, when down under a jacket it insulates the neck. It could not ask for a more versatile layer.

It's a great mid-layer for skiing, and it's equally good for climbing in cool weather because it's thin and flexible and doesn't hold you back. It does have its shortcomings though. The zipper goes up to about to your nose, the strange cuff at the bottom gets in the way, and it sticks to whatever you're wearing under it like crazy. It's a great layer, but room for improvement.

The R1 hoody and I met in San Diego in March 1975. We moved into together shortly thereafter
in October 2009. Things started out great, but
then I mentioned how small its pockets were and
it got upset and started drinking. Now, it verbally
abuses me and I have to zip it up completely just to shut it up.

This is my favorite piece to wear, everyday during winter. Everything from the thumb loops to the hoody is awesome. I especially enjoy the engineering that went into it so that it doesn't ride up the back at all. You can't go wrong with this from Patagonia and is well worth the money.

This is a must have for any skier/snowboarder. Complete with thumbloops, stretch panels and a ninja hood, the R1 hoody keeps you warm and toasty underneath layers like nobody's business. The hood works great as a balaclava, key on those cold Baldy Runs

Every winter when the weather goes crazy while skiing my face always freezes and last year turned into frost bite. One day while skiing with a buddy he zipped up his R1 and I became insanely jealous. He was warm and didn't get frost bite. As soon as I got home I bought my own. I know its a men's R1 hoody but unfortunately Patagonia does not make one of women yet.

So, if your wife, girlfriend, daughter, sister or friend always complains about freezing and her face always getting cold then buy her one of these. You will never regret it and you wont hear her complaining any more.

The insulating capabilities and moisture transfer of this are awesome, and the crafstmanship and quality are typical of patagonia (by that I mean, it is built well and holds up). The thumb loops are very nice, and help to keep the shirt from pulling up. I also have several regular R1 pullovers, which I like much more. Personally, the problem lies with the hood. I rarely find the need for the hood, and it is somewhat bulky when it is not being worn. The hood fits awkwardly under any layers on top, and when I am wearing a pack it rests between my shoulder blades and the pack...and is quite uncomfortable. The zip goes way up, so that in normal use the top of the shirt folds down and makes pack straps uncomfortable. That said, the few times I have needed the hood, it was nice to have and provided needed protection. But, this has become essentially a town shirt for me.
