Product Description


Perfect for dual-sport, adventure, touring and daily riding. Fully seam taped, unlined, HT200D Nylon GORE-TEX® jeans-cut pant with full length separating side zips inner and outer weather flaps to help the pants go on and off fast yet keep rain and wind out.

Other details include: A diamond gusset in the crotch for greater sitting comfort; An inner gusset behind the front fly improves water resistance. The knees have a greater bend around a larger radius (than the Darien pant knees), allowing more freedom of movement; Radial Scotchlight® reflective ankle tab loop strips, for a natural and secure adjustment around the calf and lower leg. Front pockets have hook and loop secured cover flaps so items inside are secure. (You won't lose your keys when the pants are laid over the back of a chair…). A double layer of fabric at the seat for added abrasion protection. A vertical zippered pouched cargo pocket is on top of the right thigh and a horizontal opening pocket to the top of the left thigh. Integrated side hook and loop for easy attachment of optional hip pads. Available in even waist sizes, 30–44 regular and long. An Aerostich Money Belt (#1854) is included with these pants. Black, Grey or Tan. Imported and Made in USA

Lighter Weight, Still Plenty ToughReview by Bruce
I wanted riding pants that were a little lighter than my Dariens for hot weather riding, and the AD1 Lights looked like just the ticket. Aerostich was offering them with the hip armour included free of charge and a 10% discount for Canadian customers, due to the battered and devalued Canadian dollar. I couldn't resist the offer, and have had them now for a couple of weeks. I am very pleased with the way they fit and feel. Although they are appreciably lighter in weight than my Dariens, I do not feel that safety has been compromised at all. They are still heavy enough to offer excellent protection, especially with armour installed. These pants seem like a winner to me. (Posted on 8/10/15)
Simple, functional, perfect.Review by Errol Smith
Made in America, Goretex, under $500...what more do you want? How about excellent customer service? I bought these right before the free hip pads deal and called Aerostich up to see if they'd extend the deal to me. Without a moment's hesitation, they had them in a box and out the door to me. I was floored! What an amazing product from an equally amazing company! (Posted on 6/20/15)
NOT made in USAReview by Dennis M
I got an email telling me these pants were in stock, ready for immediate shipment including the hip armor. I come to find out that my size is NOT in stock and the entire shipment is made in Vietnam, A lot is made of Aerostitch's items being made in the USA, not Vietnam, the price does not go down for the Made in Vietnam items. These are expensive pants and now they are expensive Vietnamese pants. Come on, full disclosure always. (Posted on 6/17/15)
Tough pantsReview by Michael
My knuckles are scraped raw making simple adjustments. Ride a BMW 1200 RT. Wear BMW gear and looked at Klim. All made in China or Indonesia. Live in California, may move due to combined state and fed tax rate of 60%, but it is warm here. Read many reviews. Ordered AD1 light pants after ordering Darien jacket. Could not imagine pants this good! Can't wait to put them on in the morning. God likes these pants. It rained 2 straight days after the day they arrived. They handled brilliantly. Changed my jacket to a Darian light even though there is an additional 5 week wait. Very tough pants with the $45.00 hip pad. Give this USA manufacture your support.

Lightweight Gear: General Protection Considerations

Naturally, you want any crash outcome with as little injury as possible. If your garment is destroyed in the process, fine. Like a spent car airbag or crumplable auto-body sacrifices itself. Many experienced riders feel it's better to have something lighter and more comfortably everyday-wearable, even if it means replacing or repairing the garment after experiencing a significant incident.

Aerostich lightweight gear is intended to provide ‘just enough’ for whatever kind of accident scenario can be reasonably foreseen. So there’s a double-layer seat on all suits and pants, and two layers everywhere else one might apply higher abrasion pressure during a spill. Beneath the elbow/shoulder/knee areas there’s also a curved plastic shell over the energy-absorbing impact material. All ‘light’ Aerostich gear also contain a hidden layer of tougher 500D Cordura, located just behind each armor section.

Still, ‘Lights’ are best for moderate speeds. Personally I am ok with them to about 65 mph, rationalizing I’d probably hit the pavement at less because of braking prior to crashing. For riders who spend a fair amount of time at 70 mph and above, which means a lot of freeway time, we still like 500D Cordura garments better. But also note we’ve received many reports about good outcomes after higher-speed crashes in 'Lights'…and zero reports they performed worse than expected. –Mr. Subjective, 2014
