Arcteryx Rho LT Bottom Men's Black L Men

using as base layer under hiking trousers for work, perfect. great fit and comfort. Have been using base layer from patagonia which has been good but after constant use this year has holes in it, it hasnt really held up. One from icebreaker is a bit too thin and not enough warm in cold conditions if not moving a lot. This is just the perfect weight and warmth for my use, and its too early to tell, but just the feel and construction i think it will have MUCH more wear life vs patagonia thermal base layer pants

Comfortable and warm

So, I received these guys and at first I was not really sure what the idea or intended use is, they have the little outside pocket and they fit and feel almost like a tight for climbing or biking. I went to the manufactures website then I was like oh yeah, base layer. The first time I wore them, I did wear them just as tights, went for a walk with my dogs it was in the 30's (F) and id say my legs were cool, not warm not cold but comfortable.As fate would happen, temperatures dipped, and we started to receive snow here in Southcentral Alaska. So I started wearing them as their intended use, a base layer under what I wear as shell pants. In 20's with moderate activity like walking at a decent pace they are pretty darn warm, almost too warm for me and my comfort, ... MoreSo, I received these guys and at first I was not really sure what the idea or intended use is, they have the little outside pocket and they fit and feel almost like a tight for climbing or biking.

In 20's with moderate activity like walking at a decent pace they are pretty darn warm, almost too warm for me and my comfort, teens are a bit more comfortable although thats me and I run warm. Below that I would add a layer, mind you these are a little bulkier than any base layer i've ever worn but I typically wear wool.These would be great for moderate temps riding the lifts, in colder temps teens and below if you are doing more active pace like saying skinning up to get some turns or fat tire biking they would be great as a single layer.They do have a soft feel next to your skin and are pretty breathable, I like the cut, fit and feel. Im 5'8 and got a large but they are a tad long i'm sure I could do a medium.The longer I own them the more I think situations or uses, these would be great for a climbing trip where your hanging in the tent, stow a lighter in the pocket. Or Hut trips, you've skied all day shed the shells and boots and now just want something to brew up some hot water in. All and all a versatile and solid product.

Extra warmth for low exertion activities

The Arc'teryx Rho LT base layer bottoms are advertised as "lightweight" but I would call them more "medium" weight. This is an ideal thermal base layer for (a) low exertion activities in cold temps or (b) folks who get cold easily like me! The Rho LT bottoms use Arc'teryx's super soft Torrent™ fabric, which is lightly brushed on the inside (for increased warmth and moisture transfer) and smooth on the outside (for no friction or chafing when worn under other clothing - even jeans!) The fit is perfect for those of us with biker legs (i.e. trunks!) and the length of these size Large bottoms was perfect on my 6' frame. The pants are (mostly) form fitting and stretch easily with movement, but never feel too constrictive or like they might fall off – I suspect the ... MoreThe Arc'teryx Rho LT base layer bottoms are advertised as "lightweight" but I would call them more "medium" weight.

The pants are (mostly) form fitting and stretch easily with movement, but never feel too constrictive or like they might fall off – I suspect the articulated patterning and gusseted crotch are responsible for this freedom of movement. The waistband is flat and comfortable, so there's no bulkiness at the waist when layering. THere's also a SMALL thigh pocket where you could stash keys or a small phone, but honestly I can't see myself ever using it (it's awkward to reach under your outer layers to dig something out of a thigh pocket.) The color I got is "Pytheas" and it's a subtle mixture of dark green and turquoise. I would HIGHLY RECOMMEND these to anyone.

My wife says I look like Peter-Pan

The material is great, supple and so cozy! Not five stars due to some of the seams being "pokey" and of course, the thigh pocket that can fit almost nothing. I love wearing these around the house on cold mornings and this is a perfect layer under my Gamma pants when it's cold in Joshua Tree. Excellent range of movement on routes as well. These will not limit you in any way. I just wish the seams were sealed properly and didn't randomly poke my legs.

Soft and comfortable

Upon initial unboxing of these base layer bottoms, I immediately noticed how soft the fabric was. They’re exceptionally soft and I was so excited for them. They seem to be very well made. Really top notch quality. I’m 5’11” and usually wear an XL in base layers and pants so that’s what I ordered. They were a perfect length but seemed to be a little loose fitting. They seem warm but not sure I would wear these through the winter as a base layer. They’re great for a warmer lounging about pant. The small zip pocket doesn’t fit much in it though. Enough for my AirPods or chapstick but that’s about it. If you’re planning on wearing them under outer pants, I’d get a size smaller than you normally would wear.

Solid Long Underwear Pants

These are quite comfortable, rather warm, and feel durable. It's a nice polyester-based fabric that strikes a good balance of stretchy-yet-solid, warm-yet-breathable.For better or worse: these are minimal long underwear/cold weather joggers. No drawcord - time will tell if the elastic holds up, but Arc'teryx is reputable so I like my chances. NO STANDARD WAIST POCKETS. The ONLY pocket is the tiny zippered leg pocket.Speaking of the leg pocket: it does NOT hold a standard smartphone. That's a lie. No idea why Arc'teryx/REI would lose credibility by putting that claim in the description. Only folding phones might fit. It's clearly designed for just a credit card or two, a key, and maybe a folded sheet of paper or chapstick. Even if you do wedge your smartphone in ... MoreThese are quite comfortable, rather warm, and feel durable.

And these are thermals so you're going to be layering with them... so even if you *do* get your smartphone or something important in there, what are you going to do? Reach *down your outer pants* and fumble around with a zipper in the cold for what you've squirreled way down there? Gimme a break!

State of the art - I'm Impressed!

Comfort. Fit. Function. I can't believe how soft these are. Normally I must wash anything next to my skin, but I've worn these several times and haven't needed to wash them yet. This base layer allows freedom of movement while just snug enough to easily fit under a variety of bottoms. I'm 5ft 11in, 185 and wear 32x32 pants. The medium was perfect for me and would be great for taller guys - there's probably another 3 or 4 inches of length. The waistband made layering easy - I don't know how they did that. No fly leads to less complication and less weight = thank you! The slash pocket is great for a garage remote, keys, or a couple of ID cards but would NOT fit my smaller smartphone. I've been gravitating toward black bottoms, but the green color looks great. The ... MoreComfort. Fit. Function. I can't believe how soft these are.

I've been gravitating toward black bottoms, but the green color looks great. The contrasting pocket color stands out but it stays out of the way if you don't need it. I wore this with gym shorts out for a jog in brisk weather and the pocket access was perfect. I went on a short hike with lightweight tech hiking pants that fit snug on my thighs; not great in 30deg weather. Combine this with more loose fitting long pants and you get surprising warmth. I wore under a pair of straight-cut denim jeans (slightly loose through the leg) while clearing autumn leaves and again while shoveling snow in 20deg weather; this kept me much warmer than usual and I didn't have that redness on my skin afterward. Nice work, Arc'teryx Team!

Supple base layer but good for cool activity too

Great cool to cold weather product for outside activities. The muted color of the bottoms I got are fine. but as a color-blind guy, this is not my strong suit. The fabric is extremely soft and stretchy – making for a very comfortable fit for all positions. They compare well in comfort and fell with merino wool base layers of similar weights.I got the medium size as I have a 32-33” waist and was concerned that the length would be too short for my 34” inseam. However, the fit is perfect. I think that has something to do with the stretch of the fabric. Though they fit comfortably from my waist to my ankles they would likely accommodate various inseam lengths.I have only used them for long walks and single-track bike rides so far and find them perfect for cool, not ... MoreGreat cool to cold weather product for outside activities.

I look forward to using them as underlayers beneath shells or insulated pants for biking and skiing once snow arrives here. I will consider getting an upper base layer to replace some of my older items.

Very poor fit and design for newly updated model

Newly updated model has very poor fit and design comparing to prior models that had such a great feet. New model has very high waist line that has a thicker band that is very uncomfortable positioned so high above the waistline. The overall length in size M, is 2.5" longer comparing to prior model that creates multiple wrinkles and would result in hot spots in the ski boots. I am 6'1" and I only see this product fit properly for someone who is way taller that I am, to compensate for 2.5" in wrinkles. Very disappointed. Arcteryx stop changing sizes. I used your products for 20 year and this one is the biggest disappointment.

Warm base layer

I purchased the Rho LT bottoms and was overall satisfied with them with some limitations. The range of movement in these base layers is amazing. I never feel restricted at all. I would say they are a little on the warm side but with a breathable shell with vents it’s never an issue. The base layer pocket is pretty small so I probably wouldnt ever use it unless I need to store a credit card. The base layer fit perfectly but it was a little bit too long and it bunched up a little bit on the bottom. Overall pretty satisfied but I wish they were shorter.
