You'll take the versatile Patagonia R1 Pants everywhere you go in the backcountry.

The Patagonia Men's R1 Pants work great as a heavy base layer or as a less-bulky alternative to fleece bottoms. Patagonia's stretchy R1 fabric moves with you and wicks perspiration away from your body as you skin up a ridge. A brushed elastic waistband provides a comfy fit, and the smooth fabric slides easily against outer layers. These trim-fitting pants also work as wear-alone loose tights for trail running and other highly aerobic activities in cold weather.

Here's what others have to say...

There are cheaper and roughly equivalent alternatives...

You may care to look up TRU-SPEC Gen III Level 2 ECWCS Drawers instead (I did). These can be found almost anywhere for much-less-than-half-the-price-of-these. The only differences I can see are that the TRU-SPECs have:
1 - a much lower and more roomy crotch area (which some may say is not such a bad thing); and
2 - a very simple elastic waistband i.e. not covered with R1-like material.

...and of course they don't say "Patagonia."

These pants are slim fit, and are used a base layer, but they're perfect for just chillin' and hanging out. You can wear em' like pajamas or as their intended purpose as a base layer. they're super warm, and have a back pocket to hold your wallet or iphone. whatevs. if you get the R1 top it can also double as a ninja costume. This is some of the base layer pants I've ever owned. i'm 6'2 w/ 32 waist and weigh 170lbs and i got the medium.

perfect baselayer for snowboarding

I bought these pants, and i bought a small thinking they would be tight, they wernt like tights like everyones been saying, but they are snug. They kept me warm throughout the day. im sayin good buy

So I own the R1 pant, looking for something...

So I own the R1 pant, looking for something heavier to wear when it's a little colder out. Looking for a long underwear bottom that is going to be super warm! Maybe double what the R1 provides. I love Smartwool products, midweight Smartwool bottom going to be what I am looking for? Open to any suggestions though. Thanks!

Eric, Check out the Patagonia Merino 4 Bottom. Easily twice as warm as the R1 pant, and possibly the warmest base layer available on the market. Patagonia wool is the softest out there, and most environmentally friendly

Awesome Baselayer

I just tried out my R1 pants (more like a thick long underwear) in sub-zero temperatures for the last 4 days while on the job for 12 hours (Outside 80% of the time) and my verdict, BEST base layer ever. I am moving around ALOT and carrying heavy hoses/guns and I never got too hot down there. Definately great for cold weather (-10f with winds gusting to 60mph felt like a breeze). seriously, buy these pants.

Not a pant, but still amazing

So, its true, these aren't a pair of pants/sweats I would wear outside of the house. And they don't fit tight like Cap. or wool base layers. That being said, they're great to climb in (think Smith Rock and 23 degrees), ski, sit by the campfire, etc. Due to the not so form fitting, these work great as a mid layer for really cold days as well. The quality is great - I've had mine a year and they still look new. Do an alright job of blocking the wind, but better with any sort of outer pant/shell of course. I'm 6'4 180 tall and lanky and a large fits well, but a medium would be better for a tighter fit.

What is the texture of the R-1 patagonia's??...

What is the texture of the R-1 patagonia's?? Does the surface of the fabric look like little squares.

Responded on

The inside of the fleece is little squares, but the outside is smooth

Responded on

The surface face is smooth but you can make out the internal fleece grid on the surface of the fabric. It isn't screaming at you but you will notice that there is a slight grid pattern. The side of the fabric that faces your body has a chunky grid of raised squares. Acts just like the old cotton thermal underwear, trapping air in the grid pattern, but it is way more efficient/warmer, wicks like crazy, is lots lighter and dries super-fast.

Great Thermals, but Not "Pants"

While unable to test in the extreme conditions I had hoped (summiting Mt. Washington mid-January and due to absolutely Everest-like conditions), I have spent some quality time with these Rs throughout the coldest December/January Ohio has undoubtedly seen in the last few years

Being a thin, six-foot bean-pole these thermals in size medium did not fit overly tight for a base layer. The elastic waistband is just barely tight enough for a 30 waist. They are intended to be snug, but not tight not as tight as thermal underwear. The mostly spandex material is light, compressible, and quite comfortable, while the raised and checkered texture gives you something to think about the first few wears. It is a bit odd, but provides for superior loft of the fabric above your skin to provide very good insulation. The mens version comes with a rear zipper pocket that might be useful if using for cold-weather running, but could probably be done without. More importantly is what the pants should have - a zippered fly with an insulating flap. You dont want that area to freeze for sure, but it would be nice to be able to keep these very warm thermals all the way on when going about business, youre already stripping off outer layer(s) as is

And boy are they warm. While climbing in Arkansas this past December these never came off. Standing around the crag in low/mid 40s and wind my legs were never once cold with these under a light hiking pant. The pants are also extremely flexible and stretch really well, no pulling whatsoever. Back in Ohio hiking with 30 or so pounds to train in single digits (but no wind) I actually had to zip off the bottom portion of my pants I was so warm. Running in low 20s and wind with just running shorts over (I still cant wear totally form-fitting I suppose Im a self conscious bean-pole) resulted in a similarly sweaty outcome. They are, however, surprisingly breathable and dry very quickly due to the R1 fabric technology.

All in all these are great thermals, but just maybe not great pants. From my experience would be best for very cold weather in active use or medium cold weather if planning to be static. Patagonia made this superior piece of clothing to keep you warm, dry, comfortable, and alive - and the R1 technology does just that. No frills, no extras.

Does snow stick?

Does snow stick?

Responded on

Well, smooth but I think dry fluffy snow would be all over you. It is not a hard, slick face surface and it isn't treated, so if this is it between you and the snow, the snow will stick to you and start to soak through as you warm it up. It wicks really well and dries quick, if you do have to stand around in the snow in your R1 skivvies for a while. Maybe this + some Patagonia Traverse pants over it?

Great Pants

I wore these as my base layer under my Burton un-insulated snowboard pants and was perfectly comfortable! Highly recommended and great quality!

Responded on

These pants are the best for toasty warm layering. I wore them under my outerpants pants on several multipitch routes in 40 degree weather in city of rocks ID. Hanging belays were warm and comfortable with these on!

5 5

Perfect weight and warmth

Perfect for a base layer under heavy gortex shell for skiing or as a running tight in moderately cold weather. They are tights rather than pants in the sense they are form fitting but are not so overly tight that they would make a person feel self conscious when worn alone for running.

5 5

The Best!

I skied with these and stayed warm. They are the Best! I was warm without question.

Can you wear this as an outer layer apres...

Can you wear this as an outer layer apres ski or lounging around the house?

Responded on

Sure, they aren't nearly as baggy as sweatpants but they're super for hanging out in. If you're comfortable with a tighter fit then by all means.

Great Middle Layer but Pricey

I use these as a middle layer (between capilene base layer and hardshell outer layer) for winter activities. They are form fitting for effective moisture wicking and much less bukly than traditional fleece. Great pants, but a bit pricey.

man i love these pants. i use these for just about every day skiing. sometimes they are too warm, though not often, they are quite versatile. some of the BEST base layer.

I bought some patagonia bottoms three years...

I bought some patagonia bottoms three years ago at a clearance sale and really liked them. However, I cannot find a similar product anywhere. The fabric appears to be wool, but it is not flat - the fabric looks like very tiny bubble wrap. it is extremely warm and very light. If you know where I can get this patagonia product, please let me know.

Responded on

I think you've either got this R1 pant, or possibly a capilene 4That would probably be Cap. 4. The checkered pattern on the R1 pants is quite a bit heavier.

I wear these underneath my waders when fishing and use them for insulation when skiing in the winter. They keep me warm without too much heat/excess fabric. Need to get another pair!

These are warm tights with a fancy design to better wick moisture from skin. Very light weight. I prefer capeline pants.

2 5

They are tights.

Not pants, these are cut and fit like tights. Useless for skiing because pulling them up will cut off all circulation.

The R1 pant used to be a loose cut pair of pants that would fit smoothly beneath a pair of ski pants, be loose and flexible. Please bring it back :(

Responded on

If the r1 pants you bought are cutting off circulation, get a bigger size moron...

I have both the old loose cut and new tight cut R1 pants and I prefer the tighter fit. For me it makes it easier to slide my snowboarding boots over them, with the old loose fit, I couldn't do that. In no way do they cut off circulation, they are great for skiing/snowboarding.

Responded on

Sounds like someone put on some weight and tried to fit their big butt in a small pair of pants. Discard this reviewer, he's obviously in denial.

Responded on

lame review. these are perfect for sliding pants over because they're slim fit and hug your leg more like a real layer is supposed to do. pay not attention to this review.

Responded on

C Johnson is right; if you have an athletic build (a skier or cyclist with a slim waist and muscular legs), these pants fit horribly. And I actually prefer a super-tight fit for base and mid layers. I love the R1 top and really wanted to like these, but they don't work.

The waist is loose, but my thighs are practically ripping the seams. I can't bend my knees freely, and, as C Johnson said, I can't pull them above my ski boots because the bottom of the pant leg won't fit over my calf. I can't size up because the waist would be way too big.

I'm disappointed because I love the material, but the shape is all wrong.

Also, I don't know anything about snowboard boots, but if you can fit pants this thick into the upper part of your ski boots, your boots don't fit you.
