Fly Butane Pants 4.3 5 16 16
Saved my Knee when I had an accident! I am not sure why Revzilla folks tell you to buy Jacket Gloves and Riding boots first and then worry about Riding Pants. I say get everything , Riding pant is as important as a jacket / gloves / boots. I was wearing this product when I met with my first accident and my lower body was well protected. I dragged my knee on the road and to my surprise my knees were spotless! I could see the scratches on the knee cap portion of the pant but this protected me, it did the job! I am happy with the fit. I am a 36"X34" for jeans and I bought 38 size. I can wear this on top of a jeans without the thermal liner. there are lot of pockets for storage. June 27, 2016
Warm for the winter I'm riding in 44 degree weather without the liner. Can only guess that the liner will take me down to the mid thirties anyhow. Bought the 34's and with a 32 inch waist I easily wear these over my regular jeans. Product is exactly as described. November 4, 2013
They seems nice for the price. They seems nice for the price. Hope I never need to find out how they perform, but so far so good. They are a warm pants especially with the liner in. the knee protection is there. Which they has hip protection, but what are you gonna do? October 14, 2013
Skinny jeans anyone? After discovering that my Mercury 2.0 pants were way to short in the inseam to wear, I found the Fly Racing Butane pants as a comparable item, with a slightly longer inseam. I decided to give them a go and found a great deal online. When they arrived I had to measure the inseam on the 40T that I ordered and they read 37". The pants seem to be of ok quality. I'm honestly not super impressed, but have limited options at this price point. I typically wear a 38"x38" jean, and after reading the reviews decided to try a size larger as I will be wearing these as an overpant, or at least that was the idea. It's a good thing that I did, because I don't think I'd be able to even pull on the 38". I haven't ridden with them yet because I have been tossing around the idea of returning them. After trying on the Fieldsheer Mercury 2.0 pants, I was a little disappointed with the quality of the Fly Butanes. The fit is very snug. Typically, this wouldn't be an issue for me, however, in the riding position (just sitting on the bike) these are pretty uncomfortable behind the knees. I would think this would have been considered by the manufacturer. I need a winter pant for commuting about an hour in weather, and I am not sure how warm these pants are going to end up being. Wearing them around the house I figured they would be too warm, but i haven't noticed that being an issue. I hope that after I wear them on the bike I decide they are ok instead of hating them because then I wouldn't be able to return them. I might have to wear them as regular pants instead, and pack my work pants. December 16, 2012
Great value just a smidge short. I'm 6'3'' with a 36 inch inseam. Best fit of the "Tall" sizes. Could use another inch in inseam. Great value and 3 season ability to ride. It's greatly appreciated to find TALL sizing. November 5, 2012
Very satisfied I bought a Fly jacket a few months ago and was very happy with it. I had thought about getting the pants as I try to ride my Suzuki Burgman as much as possible, even in temps as low as 30 degrees. With Fathers day right around the corner it was easy to convince the wife. They came in a few days after ordering them and I was very pleased with the quality, fit and style. Only small complaint is above 80 degrees they get a little hot. But I expected this so I'll live with it as protection is more important then comfort. I'd buy them again in a heart beat! May 31, 2012
Good Value I bought these pants with the Trekker jacket. A little tough to get on because of the short fly and rain gutter cover of it, but good protection in the knees and the leg zips are great. Not much venting. For sizing, I wear them over kakis with or without the liner. April 3, 2012
All been said Can't really add anything , as said , not completly waterproof , but not much is . An old pair of ( gortex I think ) waterproof overpants on top of these kept me bone dry for more than an hour in cyclonic rain . Wish the visor seal had worked that well.......... March 29, 2012
