Firstgear Kathmandu Overpants

Like the Nepalese capital, the Kathmandu from Firstgear calls out to the serious adventure-tourer. Chock-a-block full of features, these overpants have D3O armor in the hips and knees, while the bib and suspenders can be removed, depending on your riding style and mood. The leg opening is wide, making the Kathmandu easy to put on or take off over your boots. The insulated liner is easily detachable, allowing you to ride in comfort, no matter the weather.


  • Dynamic fit: Athletic, dynamic, out-of-the-saddle fit
  • Overpant is sized to fit over your clothes
  • Fully adjustable D3O T5 CE Armor in the hips and knees - delivers the same protection as standard CE foam armor, but is thinner and more flexible, resulting in a more comfortable, flexible fit
  • Back of waist yoke, crotch, inner thigh and knee back features waterproof & breathable stretch fabric that adds flexibility and reduces binding
  • Chamude suede knee patches minimize tank scratches
  • 10-1/2” diagonal thigh vents catch the air when open and keep out the elements using YKK #5 rubberized zippers - vents can be held open by folding the cover inward to hook and loop closure
  • Integrated short bib and suspenders that can be easily removed to your preference 
  • Insulated 2/3 length pant liner that is easily detachable
  • Includes 10” pant-to-jacket full conjunction zipper that attaches to your jacket
  • One time adjustable waist held in place by hook and loop closure
  • Above the knee YKK #5 two way zipper easily fits over boots – protected by an exterior storm flap with rain gutter to keep out moisture
  • Knee and leg opening now enlarged to fit over off road boots
  • Two front flap pass through pocket openings for gaining access to internal pockets – protected by YKK rubberized zippers to keep moisture out
  • One cargo pocket on right thigh for storage with seam sealed pocket bag to keep moisture out
  • Internal storm gator with silicone grip and elasticized for a snug fit to keep moisture from traveling up pant leg
  • Zippered fly-wide- gusset for easy on/off-waterproof and breathable
  • 2 Year Limited Warranty

Note: Jacket sold separately. If you are between sizes, we recommend ordering one size smaller.

Great price! Good gear These pants are great! First I've owned. Not totally waterproof and not very breathable. Pretty hot in the summer. Took this gear through canada for 7,000 miles and my crotch and but got wet. They hold water so they get heavy. But I would rather have this on than the trash bag like cheap rain gear. Knee pads are great and adjustable. I wear forma adv boots and I can not put the pants on while boots are on. I often found myself thinking I put something in my pocket but just put it in the pants and it falls to the ground. These pants are great protection from falling and water. My rain experience with these is 3 hours of rain dry on the inside 2 days in a row of rain... your but and crotch get wet. From the pooling of water in those regions. August 8, 2016
Great Overpants! First things first - I'm a brand new rider and am also a card carrying member of the Cold Weather Wuss Club. I hate being cold. These pants are great! I got them with the Kathmandu Jacket and went for a two hour ride with temps in the low 50's. 10 minutes into the ride I pulled out the liners. A bit later I opened up some of the vents. I was VERY comfortable. Haven't done any riding in rain or warm weather, but I am extremely confident these will serve me well here in Colorado. April 5, 2016
Great Pants and Service I love these pants. After reading the reviews, I ordered 1 size larger and they are the perfect fit. They are easy to get in and out of, not baggy and bulking, and the shoulder straps are a nice add-on. I wear these commuting 30 miles to/from work and wear my slacks underneath. I also have to give Revzilla's customer service a "10". I ordered another pair (different brand) that were way too long, so I called customer service. They made a few recommendations, sent me a free shipping label, and made returning really easy. Great advice with a friendly attitude. February 28, 2016
great overpant for the money I appreciate reading other reviews before I make a purchase but I don't like to write them myself - I figure it is time for me to "pay it forward." I bought these pants to be worn as an over pant for a 5 day camping / hoteling in the Mohave and Death Valley deserts in CA with the wonderful folks at Rawhyde Adventures where I rented a brand new BMW 1200 GSA. I'm 6'-3" 240 pounds and I purchased the size 40 tall. the fit was perfect with enough room for regular jeans underneath or just Under Armor. temps ranged from mid 30s to mid 60s with an occasional 70 degree snapshot. I also purchased a KLIM Badlands jacket but couldn't swing the cost to get the KLIM pants. I could not have been happier with these pants regardless of the price. they will be my go-to pants for off roading. nit picks #some have mentioned these in other reviews#: the Velcro at the boot gets a little tangled - didn't bother me but I could see it bugging others. could of had another cargo style pocket - one wasn't enough for my needs. I didn't use the pass through pockets #to get access to my jean under layer pockets# as they weren't large enough and didn't align with my jeans thus being a pain to use. overall very good piece of riding gear.

Great pants, a bit long I'm not sure why cycle gear apparel makers think they need to increase inseam length whenever waist size increases. I bought these in a 48" (comes only in 33" inseam) but I only have a 30" inseam. Therefore they are very long on me and drag the ground when I walk. The velcro strap on the bottom doesn't cinch up very tight which doesn't help. This is my only complaint. Otherwise, they are comfortable and warm. Didn't get to use them in very warm weather so not sure how well the vents work. I wore them in some torrential rain on my Super Tenere and they didn't leak one bit which was the primary reason I bought them. I like the suspender straps as well...overpants seem to have a habit of sliding down over time. October 13, 2015
Solid pants, but they're warm. I've been running these pants for the better part of a year now. I've worn them in a wide range of riding conditions, including a couple different bikes, and a few long-ish (1,500mi, give or take) multiple day trips. General opinion of the pants; well made, comfortable, easy to get on and off, plenty adjustable, etc. In short, I think they're great. I can get them on and off over size 13 steel toe work boots without much issue, which is quite nice. There's really only one pocket, plus pass-through zippers to reach your front pockets on your normal pants underneath. I don't mind this, but some people probably prefer more storage. The pocket that does exist has done a good job of keeping the contents perfectly dry through 10+ hours of driving rain, which kind of blew my mind honestly. I keep my wallet, bike key fob, and an ink pen for writing down mileage on gas receipts in the pocket. I bought a size over my normal size. I originally bought my normal pants size, and they fit just right. I decided to exchange for one size up, because there is velcro to adjust down, but no real room to size up if I wear bulkier undergarments (or become a competitive eater). Gripes/moans: They're hot. There's one vent on the upper thigh of each leg. This is alright if you're riding in ~60-70* weather, but it's just not good enough for mid-70's and up. Last week, I rode them all day through high-70's to low 90's weather, and ranged from 'consciously uncomfortable' to 'downright miserable.' I had to pull over at one point and strip my gear off at a gas station to sit in the shade and eat some ice cream. I literally don't remember the last time I ate ice cream. This does work well for colder weather, and I've run these down to high 30's comfortably. They're not brilliantly waterproof. I've ridden them in POURING rain for commutes and come out bone dry on both ends. Consistent rain for 60 miles, same story. Last week I rode around 600 miles in almost nonstop rain, and was decently damp between my legs at the end of all of it. Not soaked, but my pants were very clearly wet, and it was easy to feel during the ride. Things I'd like to change: The zipper that holds the suspenders onto the pants in the rear likes to unzip an inch or so. Minor annoyance, but it'd be nice to have a snap retainer, or a locking zipper of some sort to keep it in place. I realize many (most?) riding boots don't have laces, but I kind of wish the inside cuffs had a hook or something to hold on to your boots to keep them from blowing up in the wind. If I stretch out on my engine dresser bars/highway pegs, it tends to blow the interior cuff above my boot, which has then led to wet feet when rain picks up later in the same ride. The pads do seem a bit out of place, depending on your bike. I got the knee pads to a good placement for my Triumph Speedmaster, but on my R1200GSW, they seem to be too far inside my legs, and not over my knees as much as I'd like. Overall, I love the pants. They fit the bill of colder weather/waterproof pants nearly perfectly. Aside from a few minor functional complaints, they're awesome. I'll definitely be buying another pair of pants for warmer weather though, because these are pretty unbearable for any type of summer riding. July 17, 2015
Works well Have not had many opportunities to wear this yet. Purchased for long west trip. They do seem somewhat too baggy however I really don't care as I'm not wearing them for a fashion statement. I did have them on in a small rain storm and I was totally dry. I wear them mainly in Upstate NY but not in Florida where we have a winter home. Bottom line is I think this will work just fine for my west trip. July 14, 2015
Right On! Without paying for something with the GoreTex label, this pair of pants is top notch. Definitely true to size and if you are between sizes, go one size bigger. I've had these only a few weeks and they are already worth every cent. Adventure rides and commuting to work, these pants have already done it all in a short time. Will recommend these to anyone looking for great bibs under $300! June 2, 2015
