Hi, guys. There is a question about size. I'm 177cm(5.8ft) tall, 65KG, and my waist is 83cm (between 32-33in). I should be fine with M according to patagonia sizing chart. However, I'm slim guy and I feel good in S with Icebreaker and Arcteryx long bottom underwear.

Should I stay S or go for M as sizing chart suggeted? I'm new to Patagonia product.

If you like how bottoms from the other brands fit you, I think you could go with the size small here and be happy with it. I'm not sure on arcteryx, but icerbreaker bottoms do tend to fit fairly similar to Patagonia.

I'm trying to decide between these and the icebreaker bodyfit 200 (merino wool) bottoms...

I'd wear them under jeans to keep me warm on my way to work (5 mile bike ride)
and on weekends to go rock climbing.

The temperature ranges during the day from 35 to 60

Capilene 2 would be a great option - good warmth, fast dry time, and durable/long lasting. Would be perfect for the temperature range you mentioned.

Warm and Dry

These pants kept my man warm and dry while snowboarding. He really like them. Also, I love Backcountry! Their customer service exceeded all of my expectations.

Very comfortable

I bought these for my 70+ year old father and he loves them. He is very cold-natured and has only know the waffle style of thermal underwear. He loves these. He mainly uses them for umpiring softball games on cold days, but he admits that they are so soft and comfortable, that he wears them around the house too.

i am 5/10 about 170 with a 33 waist and the Large was much to long and would bunch up a lot. Going with a size Medium...

Smooth and Warm

The Patagonia Men's Capilene 2 long underwear bottoms are warm and smooth, perfect for putting under bike tights and ski bibs. Plus, there's a fly which earlier models lacked.

Perfect Base Layer for my ski trip. I got them last minute and they were perfect at a good price. Nice and toasty, yet great wicking layer. Awesome! I will probably make the investment for multiple Capilene layers for different temperatures to add to my kit bag.

WOW i didnt think these would be so warm! They are great! Warm, true to size, dont shrink in the wash, dont make me over heat, and dont smell to much either! Actually I think I am going to go ahead and get me another pair right now!

Simply Awsome

Performance and comfort, the mainstays of the Capilene 2 Bottoms. These base layer pants keep you warm and dry and feel great against you skin. I wear them on the slopes under my Patagonia Sidewall pants or even at work for really cold days out in the field. Simply put the Capilene 2 series is awesome.

great base layer!

These bottoms are awesome. Give a lot of warmth without a lot of bulk. Very comfortable!

great pants

I wore these as my only layer under some Oakley snowpants and went snowboarding in northern Japan for hours. Perfect amount of thermal control, not too warm when active, still not cold when walking out the lodge after lunch. Very soft and no stink!

I wear 32x30 in jeans and I got these in a medium, they give me a little bit of length to spare. I wear these in my sleeping bag and under my running and ski pants. Dry super fast, don't get smelly, and are just plane comfortable.

WOW!!! NICE!!!!!

I don't give things 5 stars unless they amaze me. These pants amaze me! I been making a transition from old school to lightweight backpacking/camping over the last 1 1/2 years. In the case of these pants it meant trading in the old faithful cotton fruit of the looms for a lightweight baselayer. I went back and forth trying to decide which brand and style to go with and the Capilene's seemed to be overall the most favored. I am glad I went with these for several reasons. First, let me get out of the way what I think may be important to some...

I am a 32/34 waist and am about 5'7". For those of you somewhat fitting my description and want the painted on pants look I suggest you get a small, not a medium. My mediums aren't 'baggy' but they arent exactly tight fit either. For me they are perfect as I don't like really tight fitting baselayers. My 'boyz' don't like the cramped quarters either, ya know!!! While they aren't overly bunched up around my ankles due to the longer length for my short legs there is a little. However, this is not a problem for me as I am pretty used to that with nearly all baselayer long johns Ive owned, fruit of the looms included.

Ok, here's what I love about these pants: the waist band is super soft and very comfortable. I have been wearing these all day and have not noticed the band rubbing around my waist like the old faithfuls are notorious for. The cuffs at the feet are a half inch hem as opposed to the 3 inch hem on old faithfuls. They helped keep my legs warm in the upper 30s this morning and didn't make me hot after it warmed up to the mid 60s. Even after it got warm and I was still rather active I honestly couldn't tell I was wearing a baselayer, especially since they wick away the sweat so great. That's deinitely a big change form old faithfull. These pants also weigh nothing at all and can almost be packed down like a pair of womens pantyhose; it's insane looking at the comparison between them and my old faithfull FOTL's. I can't believe it has taken me so long to get with the times and come goodness at the weight and sheer volume I have been packing all these years. I understand you can run down to WalMart and get some FOTL undies for cold weather for bout 10 bux, but do yourself a favor and spend the extra 25 bux for some Capilenes. You will definitely be glad you did!!!! I highly recommend The Patagonia Caps and will personally be getting entire sets of these from tops to bottoms to briefs. Oh yea, one more thing I found people complaining about in reviews but I luv the easy access P fly. Who wants to fight to free Willy when ya gotta pee and its quite chilly? LOL, freal tho...those days are quite over as the Caps offer easy access to the Chief!!!

Bought these in an XL as a gift for my boyfriend. Those were a bit too big, so I exchanged them for a large. He loves the new pair, and says that they are extremely comfortable. His office is pretty cold, so he wears them to work most days under jeans.

Meant for Warm Weather, Not Skiing

These pants are great, but the Capilene 2 is very thin and meant for warm weather, not cold weather. I didn't realize this until the pants arrived. The Patagonia tags clearly position the 2 as for keeping you cool in warm weather, not the other way around. For cold weather, like skiing, you really want at least the Capilene 3. I returned these and got the 3 instead, and I am very happy with them. The 3 is also fairly thin, so they won't make you too hot when skiing. I liked the 3 so much, I also bought a pair for my 10 year old son.

Deceptively warm

They don't look like much...hell you can even see through them if you hold them up to a light. But the temps this morning at Jackson Hole ranged from 5F all the way down to -2F (up at the summit) and I was able to stay warm with only these and my Arc'Teryx Stingray softshell pants. I did get a little cool/cold (not freezing) going up lifts and standing around, but when I was moving these kept me warm and dry.

Husband Likes Them

Bought for my husband who is a farmer. Very lite weight. He liked them. He said the heavier ones would have been to much for Illinois.
