Fly Butane Women's Pants 4.1 5 16 16
Well-fitting, feature-full, budget pants I'm a women's 12 in regular clothes (29" waist, 41" hip). I bought the 9/10 size and it fits really well. Snug but comfortable. With the liner in, I can only comfortably wear a base layer. With the liner out, I can wear these over my regular jeans. The velcro adjustable waist is really nice as it allows me to cinch up the waistband so there is no gap when I'm in the riding position. It also feels very secure on my body, so I don't think they will be sliding off in a slide. They are a touch poofy and do make some noise when you walk. To me, that's not really a big deal. I'm 5'8", lots of leg. The knee armor actually rests over my knees! The armor is also pretty flexible so it's not uncomfortable to wear. I like being able to cinch up the cuffs with velcro so they won't get caught on my foot pegs and to prevent wind from creeping in. The legs on the zippers are two-way (on the outer shell only), so you can unzip them from the top for a bit of airflow. The insulated liner does not have this two-way zipper. Things I don't like: Soooo much velcro. They are so noisy to take off and a bit of a nuisance to get on and off if I want to keep my boots on during the process. I've had these for 2 years now and some of the velcro pieces along the leg have come unsewed/unglued. Also, some of the stitching on the leg zipper flap has come undone. I've had to sew/glue some velcro patches back in place. Annoying. But the pants have stayed together in all the critical areas. They do keep me nice and toasty in the fall/winter months here in Chicago. I haven't had them out in a serious downpour, but for the brief cloudburst here and there, I've had no problem staying dry underneath. If I could do it again, I would get these in the all black color. Oil, grease, and grime doesn't wipe off very easily, and it's very visible on the silver color. This is my first experience with Fly Racing brand. I come away with the impression that they make a good-fitting, protective, and feature-full product, but that they cheap out on the finishing touches just to save themselves a few bucks. I would consider Fly products in the future, but only at sale or closeout prices. My 4-star rating is based on the sale price. These would be 3 stars at the full asking price. November 2, 2015
Inexpensive but not "cheap" We bought these overpants for my wife - who often complains of being cold on bike rides at temperatures between 15~25ºC, so these pants were supposed to handle that issue. On the first ride, at nearly 32ºC for a full day, we discovered that there is ABSOLUTELY NO AIR FLOW in these pants, even if the side zippers are open down half-way! Needless to say, the reviews saying that these are not hot-weather or summer-wearing pants are correct: if you expect to ride in +25ºC, prepare to overheat and sweat inside what can only be described as double-layer black garbage bags. However, the stitching is great and the knee armour is adjustable - as is the waist via velcro straps - so the pants are very well made; they just lack ventilation. Were rather looking forward to a few autumn rides, and given that the inside doesn't breathe at all, we suspect they also won't let any precipitation in either! September 7, 2015
Snow Pants!! They fit nice and have a very thick liner that would probably keep you warm in a blizzard but it's hot where i live so this was NOT for me. May 8, 2015
never got cold I took a long ride to Fields Or. through rain. snow ,and some sunshine. With a temp. of 42 degrees I never got cold, these pants worked great, they run a little large, I am glad that I ordered a size smaller than I wear, good pants April 30, 2015
Excellent Product Butane pants are comfortable and perfect for riding long distance. I wore them on a trip from Ohio to Maine in October in all types of weather (sun, rain, snow) with no problems. I do wish the liner would have the ability to close the gap at the bottom as small amounts of the wind was able to flow up the pants. December 29, 2014
Poor quality & durability I bought these for my wife. After 3-4 rides, they began to break down at the seams. I'm looking into a warranty exchange now. They're warm and comfortable, according to my wife. But, don't expect them to be durable. December 4, 2014
Great Bang for the Buck Just recently bought these pants from the closeout section and they are perfect for under 100$. These pants run a little larger then I expected. They are easy to get get over my pants and the fasteners on the hips made it easier to keep them up. Also I liked that there are straps by your feet to tighten around the ankles and plenty of pocket space. November 3, 2014
Too little rise. I ordered appropriate size for all other measurements, but there was far too little rise. The pants seemed to be acceptable in all other respects, though I obviously did not wear them beyond trying them on. I was disappointed they did not work out. October 23, 2014
