Product Description


Built for hard everyday wear, long trips and extreme adventure and endurance riding. Whether you are heading across town or across Siberia, this is the toughest most reliable single-layer textile jacket and pants available.

The Darien actually was the first armored textile jacket and pants made specifically for long-distance travelers and adventure riders, and today after more than 25 years of continuous improvements and careful refinements it still remains the benchmark for technical motorcycle trip gear.

With its unique single-layer construction there can be no shortcuts. Nothing is hidden under a lining. Hook and loop is used for positioning its comprehensive TF3 impact armor systems.

Darien's ride drier and more comfortably across a wider temperature and climatic range. The armor is easier to custom-position for fit or remove and replace as required. Emergency field repairs are easier, too. (Important if you're somewhere remote.)

Cut like khakis (and some jeans), these unlined overpants are the perfect match for a Darien jacket. Two front pockets, one back pocket, a flapped front fly, and a waistband with belt loops containing a removable Aerostich belt are some practical details.

Full length side zips with inner and outer flaps insure easy on-and-off convenience and severe weather protection. Bent knees, large 3M Scotchlite™ reflective ankle adjustment tabs and shaped, removable TF3 knee armor complete the specifications. 500 Denier Mil-spec Cordura® GORE-TEX® fabric is fully seam taped for comfort and strength. Black, grey or tan. 30–46 waist, regular and long. Made in USA

If you are interested in suspenders (?) we recommend these #1815-1349. Several models and styles are available.

Another PairReview by wviands
My first pair of these pants lasted four years with no issues. There really isn't anything wrong with them but I got fatter so I needed to get a bigger pair. I'm a daily year round commuter in Maryland so I hit the road in temps from 30F to 100F, rain or shine. Yes, they're warm in the summer but the protection is more important than some perspiration. I went down once in the rain at about 20 mph and slid on my side for about a hundred feet (oily road) and the only damage was a small hole in one pocket due to keys. No complaints about these pants.

Hot in the Ozark MountainsReview by Kinghawg
I wore them for the first time last weekend. Temps in the high 90's. I had golf shorts on underneath but may have been more comfortable with blue jeans. And, I would guess a color other than black might help. I'm sure that they will work great when it cools off a bit but it's going to be a challenge to wear all the gear all the time when it's summer in the Ozarks. (Posted on 8/29/11)
Not for meReview by TB
I've had a Darien Jacket for years. I thought I'd try the pants and just could not make myself like them. They're black, absorb heat, but the zipper lets air in. They're slippery on my seat and I slide around too much. I sold them to someone else who loves them. Now I'm in BMW leather when it's cold and Rukka when it's not. I've found that I don't like the zipper up the leg thing. (Posted on 6/23/11)
Sturdy, Durable, and Rad pantsReview by lobojon
You could see my Darien jacket review for some other information.

The pants are a little breezy compared to my Belstaff. It is a shell after all. The side zippers are great for me since I wear 8” lace up boots. They are very roomy for additional layers and are very comfortable. The belt and zipper are great for wearing around like pants. The ankle adjustment strips improved insulation. I also like that I can chose where to attach the hip pads. It took me a few attempts to locate a suitable location while riding.

Wash it to loosen it up a little if it is too stiff.

Get these pants. You will not be disappointed. (Posted on 11/12/10)
Great GearReview by Matt
I have had them for about 200 miles now. Just got to work, 20 mile commute in 36 degree temps. I like these pants, warm and the fit is excellent. Leg adjustement is good. I wish they folded up better with the knee pads, but other than that I look forward to many miles with them. (Posted on 10/20/10)
Impressed so farReview by Pat Kaz
I just got these pants in last week and got to test them during a thunderstorm this morning, made it to work with a soaked jacket and gloves but my jeans were bone dry, other than a little dampness at the cuffs (probably because I wasn't wearing gaiters) I look forward to many miles in these pants.

Great pantsReview by Marius E.
I ordered the Darien pants with optional curved hip pads (#1053). The quality and protection is top notch. I wear blue jeans underneath. The crotch area is tight with the optional curved hip pads, so you may want to go up a size for added comfort if you order the curved hip pads. The knee pads were too high on my knee caps when sitting on the bike, so i adjusted them to fit my knee caps properly. With the side zippers up, I can maneuver the Darien pants over my Aerostitch Combat Touring Boots (#480). The lower leg segment fits perfectly over the boots and there is a snap button on the bottom. I ride in 90+ degree weather in Florida and have no problems with overheating. Actually, the pants protect my inner lower legs from engine heat at stops. There is no flapping of the pants at highway speeds (70-80 mph). I was completely dry in a constant downpour. I had no distractions in the rain and was comfortable in the Darien Jacket and pants. The comfort gets better each time you ride. When storing, I hang the pants by the belt on a hanger with 2" shoulder notches and allow them to hang dry. I definitely recommend the Darien pants to anyone. The price justifies itself with the quality, durability and protection. Thank you Aerostitch! (Posted on 12/14/09)
Crash TestedReview by Silviu Stanescu
I´ve had my Darien Pants for aprox 50.000 Miles. I live in the tropics. These pants have seen every kind of weather, from 110F in the hot plains and coastal regions to 30 F in the Andes. Tropical rainstorms are no match for the Goretex. They fit great and are very confortable even in very hot weather. A couple of months ago, I even had the chance to crash test them: due to an unseen hazzard on the road, I went down at aprox 50 MPH and slid on the pavement for about 30 yards on my butt and left hip. Thanks to my Darien Pants I was TOTALLY unharmed, not even a single tiny scratch or bruise. The pants held up perfectly, showing only a couple dime-sized holes on the hip area and a smaller one on the back pocket where my wallet was (also unharmed), they held so well infact that there is no need to replace them, but when the time comes, I know I´ll get a second pair without even looking around at other brands.

Great pantsReview by Sambone
A friend gave it to me, almost five years now. I was skeptic of pants' claims. It is comfortable to wear, easy on and off with boots and it is waterproof (no wet spot around the crotch area). I wore this pants on very ride. I wish that I got this pants long ago. (Posted on 11/21/09)
Great Pants!Review by Paul
I received my Darien pants 2 days before leaving on a 5,000 mile cross country journey. Aerostich customer service spent almost an hour on the phone with me trying to track down my size in stock (thanks Christine!!!). The pants fit pretty good (a little long when standing/walking which I expected with my size 38x30, but just right when on my bike). I rode through all sorts of weather...high of 102 degrees, low of 33 degrees....sunny days, rainy days, and even a couple hours of snow flurries in the Rockies. The pants were great. I was a little warm above 90 and a little cool below 40, but that is to be expected. I have no regrets at all, as a matter of fact, I wish I had bought these pants a long time ago. I'll be ordering the Darien Jacket as soon as I recover from the expense of my trip! (Posted on 10/3/09)

Gear: Fashion and Style vs. Equipment

There’s a lot of ‘noise’ in the rider-gear market space the Aerostich Darien jacket occupies, about how ‘new and improved’ similar jackets are. Other companies making these kinds of jackets restyle them and revise them every year or two, telling riders that if three zippers is good, six or seven zippers is better.

What all the ‘noise’ amounts to is fashion and style being presented in the guise of technology which supposedly is rapidly ever-advancing in this area. Except armored waterproof textile jackets are not the same kind of technology as computers, or even motorcycles. Seven zippers are not better than three, if only three are functionally needed. What counts is ease of use, durability, fit and function. The pioneering of this type of gear was done by us twenty and thirty years ago. (Combining lightweight breathable-waterproof highly abrasion-resistant synthetic fabrics, seam-sealing, ergonomically more useful vents and pockets, reflective materials and energy-absorbing foams and plastics.)

Since then, just like added decorative stitching on branded ‘designer’ jeans turns a pair of useful, comfortable and durable work pants like Levi’s 501’s into a fashion, all the noise about new tech in jackets like the Darien is mostly fashion BS masquerading as technological improvements. It’s not real.

Classic black leather ‘zipper’ biker jackets have been popular world-wide for many decades. There are versions at many price points and in some circles this jacket has become a fashion cliché having little to do with actually riding a motorcycle. But for many riders it remains a great equipment choice that has changed only very slightly over the years — because it works so well. You’ll find the original versions of these jackets at Langlitz, Shott and several other pioneering leather companies. Similarly, you’ll find the original British waxed cotton Belstaff and Barbour rider’s jackets and pants still being produced in their original patterns because they remain excellent functional rider’s gear.

The ‘latest-greatest’ is usually more style and fashion based, and original equipment is nearly always more utility-tool based. It does not change from year to year any more than Levi’s 501’s. Many riders are unlikely to admit they are buying ever-changing fashion and style when they believe they are getting some kind of improved technology, but that is a truth. None of the regularly restyled ‘teched-out’ sportswear for riders comes in as many closely-spaced sizes as the Darien does, and none is as functional and equipment-y as a Darien.

The Aerostich Darien is the original advanced technology breathable-waterproof impact-armored synthetic (nylon) textile rider’s gear, and just like the above-mentioned other examples of specialized rider’s clothing, it is similarly more equipment than fashion. For historical reasons.

Dariens are available ‘off-the-rack’ in eleven closely-spaced graded sizes and six colors. Complete repair service and several optional fit alterations insure years of superior service.

"The Darien and AD1 pants fit a little different…The Darien's fit like khaki 'Docker'-type chinos and dress pants. They have a straight waistband and a higher rise than jeans. The AD1's have a lower rise and a slightly conical waistband that is angled a bit lower in front. So these fit more like old-school denim jeans. I slightly prefer the AD1's fit."
