Toasty legs!

  • Gender: Male
  • Familiarity: I've put it through the wringer

I purchased these in January when my Cap 3s went missing. I wasn't expecting the difference in warmth between the two to be as drastic as it is. I wouldn't even think to wear these on a ski day warmer than 20 degrees. However, they do fit extremely long. I am a solid 6', and can double up the thigh when pulled to my boot tops, and when they are at ankle length, the waist band is easily fits past my bellybutton. But the Pataguch quality and warmth cannot be beat.

Ok, someone riddle me this:

Ok, someone riddle me this:

Patagonia Capilene 3: 5.4-oz Polartec� Power Dry� fabric, total weight: 6.6 oz
Patagonia Capilene 4: 3.8-oz Polartec� Power Dry� High Efficiency? fabric, total weight: 5.4 oz

Can the "High efficiency" fabric really be that much warmer? Polartec's website says the high-efficiency Power Dry breathes better, but it doesn't say it's warmer.

It doesn't make any sense that the 3 is actually heavier than the 4. Anyone?

Jacon,
Great question, and good catch. Cap 4 is an anomaly since the fabric itself is lighter than Cap 3, but is definitely warmer. The interior of the fabric is a high/low grid that does a great job capturing warmth, kind of similar to Patagonia's R1 pieces if you're familiar with those. See the attached pic for some detail...

I agree with Ty. The gridded fabric of the Cap 4 makes them WAY warmer. I have both the Cap 3 and Cap 4 bottoms, and the difference is very noticeable.

Super warm base layer

  • Familiarity: I gave it as a gift, but have feedback to share

Put these under your ski pants, and you'll be warm, even if it's 0* outside.

New approach works

  • Familiarity: I've put it through the wringer

I have had the expedition weight longjohns for years, and it was time for a new pair. I was surprised when they arrived and they were not the old thick fleece, but they are great! Great fit, warm and cozy.

awesomeness.

Patagonia redesigned the new Capilene 4 fabric to be a true next to skin, super warm baselayer. It's not designed to be as warm as previous versions, which were more of a mid-weight fleece weight. That fabric is now available as the Patagonia Piton Pullover and Piton Bottom.

I'm totally digging the new fabric. It's super warm and incredibly comfortable. Almost wears like merino, and due to the new silver based anti-odor treatment it fights off the stink almost as well as merino too. This fabric is breathable when on it's own, and captures a lot of warmth when wearing layers on top of it. For me it's the perfect backcountry skiing piece, and the shirt that I pull on almost every morning right out of bed. The interior is a micro grid similar to what you'd find in an R1 fleece, but a lighter and more breathable version. The warmth it captures is pretty awesome for how light the fabric is, sometimes it's almost too warm for me, and I have to size up to a large since a slim fitting medium is too warm. It's a really unique new fabric, and definitely needs to be worn and tested to be appreciated.

A big step down from old Cap 4

This material pales in comparison to the old Cap 4 material. The old Cap 4 was thick, warm, and soft; a true "expedition weight" fabric, as the description states. This new fabric has no place in frigid winter conditions. Patagonia: Please bring back the old fabric!

have you worn it yet? It's super warm for how light it is and incredibly comfortable. If you're looking for something like the old Cap 4 check out the Patagonia Piton Bottom

Not as warm as the old Expedition Weight

  • Gender: Male
  • Familiarity: I've used it once or twice and have initial impressions

I have a pair of the old, very thick expedition weight underwear. Despite Patagonia's description, these really are mid-weight. My first time out in them I was definitely cooler, and not in a good way. While the open-grid construction adds breathability, I've gone back to my old pair for colder days, or times when you are standing around more (ice-climbing belay, e.g.). A bit of a disappointment, and I'm a big fan of Patagonia clothing.

Christopher, check out the Patagonia Piton Bottom if you're looking for more of a direct replacement to the old expedition weight.

Equal to Smartwool

  • Gender: Male
  • Familiarity: I've used it several times

I bought these on a whim to compare them with the Smartwool midweight bottoms, which have been my normal winter long underwear bottoms.

My use of these primarily has been, and will be , be walking during the winter and commuting via bike to work (10+ miles). So far I'm really impressed with how strong they feel, as opposed to my Smartwool bottoms, which I put a finger through pretty easily. These seem to be constructed with the insulating material in strips horizontally across the legs with spaces in between that act as breathing areas. The cuffs at the bottom are nice and strong, reducing any slip.

I like these so much I may just buy another pair or two over this winter.
