Here's what others have to say...

Will this be too warm for use with Gore-tex shell pants at 25-30F with wind chill - feeling like 20-25F?

Responded on

Hey Patrick, Sounds like a good combination to me... might be a little warm, depending on your activity... but you can always vent!

Responded on

Oh funny. I just suggested these for use on your Beta AR question. Yes they're perfect, I think.

Responded on

Thanks. I'll be snow skiing. Sitting on lifts getting blasted by wind.

Responded on

The Rho AR Bottoms are *awesome* under shell pants in extreme cold: what I consider between 5 and 25 degrees plus wind. I started out skiing one morning in February in 10 degree temps plus wind. The high was 25. I was comfortable all day.

can't ski without 'em

The title really says it all for me on this one. I got these about 4 years ago and have skied roughly 75-110 days each year in them since. They show barely any signs of wear and are still as comfortable as the day I put them on. I am about 6'2" and about 170 lbs. I tend to wear larges in most pants but got these in a medium for that nice snug fit. It made the legs a tad high above the ankles which is just fine for skiing. Definitely recommend to anyone who needs a midweight long underwear.

Do they stink?? I will use these deer hunting up north, and will be sitting in 0-40 degree weather. BUT i hate long underwear that gets rank after every use!

Responded on

Don't know if they stink or not, but your best bet is wool. I only use wool now and they never stink. They're also comfy across a wide temperature range. Check Smartwool, Ibex, I/O. All great.

perfect base layer or stand alone

These polartec pants are really as warm as it gets before going into insulated pants. They are nice because they fit like a comfortable man tight. I usually wear a small but ordered a medium and they fit how I wanted them to, tight enough to fit under any pant but loose enough to wear stand alone. Also the polartec material is so soft and comfy.

These "tights" are NOT

These pants are described as "tights"

However these "tights" are loose, instead of fitting snuggly (tightly) on my legs.

Responded on

What size are you? are you sure you got the right size? :)

Use these as my warm bottoms baselayer. Used them on a recent winter attempt on Rainier. While I failed these (Plus my Gamma SKs) kept me warm in some serious wind. I also use them skiing in Washington with some Hardshell bibs. I'v used them from 25 to 50 degrees; waiting till next year to push them colder.

I love these!
Supersoft and comfortable. I've used them for randonée and freeriding, beneath my onepiece, down to -30 deg C. I haven't been cold once.

Soft and warm

These work great as a mid to heavy weight base layer under softshell pants for cold days and function good for trail running as well. good for extra warmth at night when in extreme cold camp conditions.

Good thermal protection

I have used AR under hard shell pants at about 10 deg. F. Skiing or riding a slow lift chair for about 12 min. was similar comfortable. I have used a generic cotton/wool multi-layered system before. AR is much better. I recommend AR.

Right cloth for the right weather and situation

I've been using this as a base layer alone, for really cold weather (down to 30ºC below cero) to climb and do approachs always in hard alpine style. As soon as I stop to belay, camp or just take a rest I wear my insulated pants. This way I keep my body warm enough, avoiding to be sweaty and loose heat for evaporation or convection.
