Here's what others have to say...


Warmer than expected

  • Familiarity:I've used it once or twice and have initial impressions
  • Fit:True to size

So I bought these to keep me warm. As a ski racing coach I do a lot of standing around in 20 degree temps. I decided to search for the warmest pair of bottoms I could fine. After purchasing the UA base 4.0 and 3.0, I just wasnt happy. Those two were thick and promising. But the bottoms just didnt feel good under ski pants. They had very little stretch and limited the movement. Not to mention the weird sizing.

So I decided on these and glad I did. I am 6 feet and 185 and both the M and L fit me fine. I tend to like things not too tight so I decided to go with the L. If I was racing and needed something to go under a speed suit the M would have been fine. They were just a little tighter on the legs.

The fit on these are great. Nice and snug at the waist and plenty of stretch and give in the material. No problems at all under ski pants.


The Real Deal

  • Familiarity:I've used it several times
  • Fit:True to size

I couldn't be happier with this product. As usual, patagonia goes above and beyond with function and style. I've used this on multiple fall backpacking trips this fall and it's perfect. Keeps you dry from sweat, and warm without feeling "stuffy." I've also used it the last couple of weeks for hunting to replace my old Under Armor cold gear and it did wonderful as well. Kept me warm yet unconfined. If you need a great baselayer, I can't recommend this enough.


Adequate but not great

  • Familiarity:I've used it several times

I got these as a gift so I was not worried about the cost but at $115 I was expecting more. They seem to perform the same as my $30 polyester Columbia base layer I have been using for years. They also fit baggier than I would expect for a baselayer. If it was my own money I would not buy these.


Who does number three work for?

  • Familiarity:I've used it several times
  • Fit:True to size

I have been using the three for awhile, great fit everywhere, as a base layer I may have been better off with the two's. I do notice the crotch area is a little saggy, if you are running in them, climbing is fine.
