No more boot issues

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: Large

I've got super tight ski boots, so any excess material ends up getting pulled up to my calves. Not so with these bottoms. Besides being soft and comfortable, they fit perfectly with where my boot ends near my calf. Besides skiing I've worn these to sleep while camping in cold temps, and they're amazing comfortable. Two thumbs up!

Fantastic base layer

These are awesome! They are on the warmer side for me and I tend to burn hot. I have two pair and have loved them. They are made very well and I'm sure they will last years

Very nice mid-weight base layer

  • Familiarity: I returned this product before using it
  • Fit: True to size
  • Size Bought: Large

These are very nice mid-weight base layer bottoms. The extra insulation on the knees feels very nice and would go a long way if you find yourself getting cold knees. I am used to more of a compression fit and sometime like to wear another layer, such as snug insulating shorts. The combination of these bottoms with the other mid-layer I wear on colder days just did not work quite right. The are very nice pants and would be excellent as a standalone base layer under a shell or insulated pant.


    These are comfortable and warm. They have a thicker area around the knee for added insulation and padding. I got the large and I'm 190 6ft. They aren't skin tight so you can wear a pair of compression leggings over them on really cold days. The top has a wide elastic band which is comfortable. I have way to many base layers and these are in the top 2. I also have a Houdini hoodie which is amazing.

    Great feel

    The fabric and weight of these boot-top length bottoms was great. I bought them for cooler days but it was unexpectedly warm when I skied in them for the first time. They still felt great, though and I stayed comfortable. Slight ding for being a little longer than I'd like for skiing, leaving them a touch baggy in the knees, but they didn't bind or feel bunched up. Great brand.

    I literally tried every pair of boot bottoms that Backcountry sells... yes, I ordered them all! The only ones I did not try were the Patagonia... they were out of my size in both Cap and wool.

    Of all of them the Houdini's were by far the best. Significantly better fit - dramatically better. They are a 'mid-weight'(Cap3) equivalent. I ended up keeping two pairs of the Houdinis and two pairs of the North Face. TNF's are a light-weight (Cap2) equivalent. The Burtons are just terrible - you get what you pay for. The Marmots are good (own a pair from last season) but are about 1 inch shorter than you'd want to over lap your sock just a bit. I Telemark so I wear knee-pads (Black Diamonds are the best) and the Marmots are just a tad short, they work buuuutt the bottom straps from knee pads sometimes work themselves up under the bottom cuff?exposing skin. The Houdini's are more expensive but wow are they worth it. I'm 5'9" 155 and wear a Med in most, Med in TNF but a small in the Houdini.

    Oh, If I was buying some and not going with the Houdini's I'd get the Icebreakers - they are VERY nice and I'd say the warmest - I'd put them at a Cap3.5 ... and were longer and great fit... but were WARM... I just did a week in BrianHead, 10� - 20� and the mid-weight Marmots kept me perfectly toasty...hence the Icebreakers would be too warm for me for an average lift-service ski day? god forbid I was skinning? I'd roast. I got the TNF's for Spring and or skinning.

    Get the Houdinis? they rock.

    If you like these so much and wanted it in a lighter weight, why did you go with TNF and not the 3.8oz base made by Houdini? They are literally almost half the weight.

    How thick are these? Something like a running tight, or are they thicker and more insulated than that?

    They are about same weight as Patagonia capilene 3, I'd say. What makes these unique is the knee patch - notice they are different color on these? That's b/c they put up an extra layer of thin fleece at the knee area, which makes the knees toasty. I use them to run in cold weather.

    They are similar to a Cap3 (Mid-Weight Patagonia)...and they are fantastic. better made and fit than any others... yes I tried them all. If your looking for a Cap2 equivalent go with TNF.

    James, these are a lot like the Cap 3 by patagonia, similar weight...
