Here's what others have to say...



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

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.

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.
