Rukka Outlast Pants

The Rukka Outlast Pants work to keep the wearer’s temperature not too hot... not too cold... but just right, over a broad range of environments and activity levels. When your activity level or the outside temperature increase, the Outlast thermocules that contain the phase-change paraffin begin to change from a solid to a liquid which provides you with a comfortable sensation of thermal equilibrium. The energy required to activate this process comes from your warm body or rising ambient temperatures.

When you begin to cool down, Outlast thermocules begin to change back from a liquid to a solid. In this phase change, the energy that was absorbed by the thermocules while you were active is returned to you.

Not bad Even don't know where to start. First and foremost expectations were high. I think because of all high-tech background, the promice to get the same comfort as a nasa cosmonauts especially if you concider me living in Florida - that was more than enough to make me pay $70 for something what would replace granddaddy's longjonh's. Sadly but expectations were met only on cooler side: when i came to work i didn't feel being "heated" or "cooked", but i didn't purchased it for comfort off the motorcycle. Just to be fair - it is possible that my blood thinned after so many years living in Florida, but it was cold. And no, I didn't try riding at recent upper 30° weather, rather upper 50°. And I felt cold, not to the point of stopping and layering, but it was cold. My legs, when i came home were cold to the touch and i expected them to be at list cool. So for me that's just a cooler weather extra layer, not a protection from cold. Now the quality overall isn't all that good - waist is weak, so after few moves it feels sagging. And since i believe in using belts that's uncomfortable feeling for me. But to be fair the leg material reminds me under armour cool gear. So far it stretches but comes back to original size. Again, that might be just me and my luck, but based on my experience i would recommend to try other products, may be even of same brand. February 23, 2015
Not cheap, but you can't beat the results I'm on a mission to commute to work on my bike year round. The trip is about 100 miles round trip. So I bought both the Outlast shirt & pants to try and help this goal. The Outlast base layer shirt & pants kept me comfortable indoors and out on the bike riding 80mph in 27F degree weather. I was so impressed with the comfort fit & performance of this product that I bought a 2nd set. While, my wallet yelled uncle, I can't deny it works. December 24, 2014
Great Product Wore this undergarment everyday on a recent 3700 mile journey from Seattle to Rushmore at back, where the temperatures ranged from the low 40's to mid 80's. Worked really well on the hotter days and was substantial on the cold days but definitely needed to layer dress to keep really warm. All in all a comfortable effective garment. October 7, 2014
Does Exactly as Advertised! These pants are great! Does exactly as advertised. Keeps you warm when its cold and thin enough that it lets air circulates very well when its warm. When its too cold in the mornings and too hot in the afternoons for extra layers, you can fold it up into a little ball and put in your bag or whatever. Pants make it easier to pull on and pull off race leathers when you're hot and sweaty. April 24, 2014
Comparable pricing to other choices Willing to give the technology a chance. Went riding in 45F weather, no problem. Wore it to a football game at 28F, but was one of two layers. Runs slightly small compared to Rev It base layers. December 2, 2013
Outlast pants....go with the flow Great underlayer. I went through 6 states with various climates and not one problem. No issues with seams and great comfort. October 2, 2013
My legs don't know what temperature it is outside. I've used these pants under my Dainese Drake Air pants on three long distance rides now. First was DC to NYC which started out sweltering and ended in balmy evening weather. Second, back to DC starting in 50s and rain with rain suit over my riding gear and finishing in 60s. Third, 4 hours from low 70s to mid 80s and sunny. In each circumstance, no matter what the temp was outside, I was fine, not too hot or too cold. Also, on the DC - NY - DC trip, was wearing the Outlast shirt. Same deal. I think these work better than my other summer time base layer stuff from other manufacturers. I highly recommend due to Rukka's weird, Scandanavian magical temperature regulating properties. Obviously, they know what they're doing. June 23, 2013
OK quality but wirth $69? Bought it as Dainese WS pants were not available. Fit is loose, maybe I am too skinny, and it makes my legs chilly even I was wearing leather pants. My Under Armour winter inner pants works better... February 20, 2013

RevZilla Store asked: Why did you choose this?
Adam S: I chose the Outlast pants because of Rukka's reputation for quality, but more importantly because I like the idea of how the outlast material works and the fact that it should be versatile in varied climates which keeps me more comfortable (and consequently that little bit safer) as wells as carrying that much less stuff.

"" ": I would recommend purchasing your typical underwear size. The material is very forgiving but it should fit nice and snug against your body. I am not certain exactly why no sizing chart exist for this product, however, Rukka does have a sizing chart for most of their products. Feb 3, 2015

Steve R: These are pretty stretchy, but if you're wearing 42"-32" jeans, you'll probably want the largest ones they offer Feb 3, 2015

Roger M asked: What size do I order for a 30" inseam and a 35" waist? Jan 6, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
John S: Pick the size that you normally use. I have a 37-38" waist and a 31.5 inseam and I purchased the large. They fit tightly around the waist and they are short on the leg as would be long underwear.

Yvonne L: I purchased a pair for my boyfriend. CS@Revzilla suggested purchasing the same size as his underwear. He's a 33 inseam/32 waist and I got him a size M. The material is pretty stretchy. Jan 6, 2014
