Klim Adventure Rally Air Pants 3.6 5 7 7
KLIM sizing bias I am very interested in the KLIM Adventure Rally Air and associated GoreTex Oversuit system. I live in Australia, and I currently use a similar ad hoc system of mesh-based suit as my foundation 'armour' layer, throwing warmer and/or waterproof layers over it. I arrived at this solution independently, having conducted an expensive trial of buying many and varied articles of motorcycle clothing. It just makes sense to start with a cool protective layer and build up from there, as opposed to starting with a hefty (albeit 'breathable' and vented) suit. My current mesh suit is about as cool as you can get whilst still being protected, but it is still a bit light on protection, particularly in terms of abrasion resistance. Though the whole KLIM system of mesh suit and outer Gore-Tex shell is eye-wateringly expensive, I am very interested in making the investment, as the 'finale' of my clothing trial, because I am planning a world trip in the future, and I think this would serve me well. Now for the gloomy bit. If KLIM commissioned a TV ad, the theme tune would probably be a certain Randy Newman song. KLIM is obviously doing very well, because they don't see the need take millions of dollars off the legions of worldwide motorcyclists who are below 5'10". I am 5'8", hardly carnival sideshow in stature, with a 29" to 30" inseam. Forgive me, I've just turned 50, and my waist size is 36-38". At last year's Sydney Motorcycle Show, I tried on every style of KLIM trousers (pants, to you), and not one pair could I get to fit. So, despite Revzilla's excellent returns policy, I think a purchase would be futile, because I simply don't think that KLIM want my money; if they did, they would not just tease me with 'short' entries in their sizing chart, they would marry these up to products for sale.

Klimtastic My very first experience with these pants was from Austin to Houston in the middle of August, and these pants were fantastic in the 104 degree heat..... plus the humidity this part of the country is known for! Robust. I've never seen fabric as tough as this. The armor is well-placed and comfortable. Gives me great confidence! Heavy! I couldn't believe how heavy this "air flow" pant was, and it concerned me that it would inhibit air flow. It didn't. I was surprisingly comfortable for the 4 hour travel in the Texas sauna. Size. I'm 6'3 and wear about a 36-38" pant. I ordered the 38 Tall. The waist and room through the leg felt correct, and the length was right on for other "tall" pants I've purchased. I'm guessing that they measure the length in a riding position rather than just straight up and down. This is good because that is when you WANT the length. Minor complaints. The knee armor is very low, as others have stated, with no way to adjust. However, the pocket for it is quite roomy. I will just stitch the pocket up higher myself. Shouldn't be too difficult. Just wish it was a built-in adjustment. I wish there were loops for a belt. I hate suspenders. I don't have any use for a "spot antenna" but there is a removable pouch for it. It can be removed but then it leaves a couple of weird looped fabric strips. Surely, they could've done this a different way. Appearance: The grey/black combination would look good with any other color combination. August 8, 2015
Great Pant - But they run long and no kneepad adjustment I've been enamored with the Rally Air suit since it was first announced. I wanted something that could handle all weather conditions and still be comfortable on those really hot days where no amount of slit vents in a Goretex jacket is going to help. So, I slowly started buying the Jacket, Pants, and over-shells for both. The jacket has been amazing....but the pants? Not so much. Size Ordered: 34 Regular, same as my Badlands Pro. Personal Measurement: 5'8" tall, 32-33" waist, 30-31 inch inseam. First off, let me say that my beef with the pants is not from the build quality or materials used, it's with the horrible sizing - namely the length. The sizing chart says "Regular" pants have 32" inseams and "Tall" have 35" inseams. However, that is not true on the final product. The Regulars actually measure a whopping 35" inseam! I compared to my Badlands pants which measure a true 32" in length. The overshell measures a true 32" length as well. I contacted Klim and they said that they use a "special" way of measuring the Rally Air Pant inseam, a way they don't use to measure any of their other pants. Cough....BS...Cough. They don't start at the centerline of the crotch or include the gusset...they start 3 inches lower. Wait, what? That goes against every inseam measurement method in the industry, including their own. So just be aware they run longer than advertised. The waist and thighs fit fine though, similar to the Badlands Pro fit. The next big issue is that the KNEEPADS ARE NOT ADJUSTABLE. This model of pants is different than their other pants in that the kneepads sit in a FIXED POCKET with no up, down, left,or right adjustment. So, coupled with the already too long length, the TOP of the knee pad is below my kneecap, essentially turning them into shin guards. In short, for $800 Klim really screwed up on these. Yes, they offer maximum airflow and maximum abrasion protection. But for a "premium" rally pant to be so far off on stated size and offer ZERO kneepad adjustment is really disapointing.

Nice, but they run small... I'll start with what I'm always curious about when ordering wearable gear online;"Fit". They run small. Not a complete size small, maybe half a size small. Me; 5'10" around 220 with a typical older guy paunch. I tend to wear my jeans at my hips as I have a high waist line and if I actually wore pants at my waist, I'd be buttoning them just below my shirt pocket.. Yeah not pretty. I typically wear a 38 jean with some room to spare. In general I need a belt or they will be around my ankles. These are snug. Not a full-size small but the type of snug like when you put on your jeans and you ask your wife if she's been drying your jeans on "high". That type of snugness that tells you its time to maybe pass on the dessert for a little bit and get out and walk some. These replace Olympia Air Glide 3s. Those are also a 38 but fit me like my jeans. They fit comfortably and I really could have stood to wear a belt or suspenders. The only reason I'm replacing them is I want better protection. Back to the Adventure Rally Air Pant - These pants breathe or vent really well. Standing in front of a fan you can feel the air flow through the pants. I like the "cut" as it doesn't slide down from your waist to your hips. I just can't figure out how to adjust the knee pads so they are in the correct position with knees bent. The full zipper to connect the pants to the jacket is easy to use with just a few minutes of practice.Those also help keep the pants from sliding down… I hope to never find out just how protective this gear is but I know I've picked the most protective I can for the type of riding I do. And definitely use the method they Revzilla describes in their video and you'll get a pant that is "close". Pick your jean size and you're gonna be sending them back.. September 15, 2014
Need a larger size Klim needs to offer larger sizes. Yes I could stand to lose some weight but I still like gear that fits. The 3x Rally Air Jacket is a technical wonder. The Rally Air pants - well I am never going to know as 42 is not going to cut it. I will continue to shame their reps at rallies (they can pick on my girth). Come on guys a 3X implies a large human. I like good stuff between me and the earth when the occasion arises. And it does from time to time. Based on my great affection for my new Rally Air jacket I would really like the britches to match. So I am pleading (Klim, are you listening?) please offer some larger sizes (46 hint!). I eagerly await in hopes of an encouraging reply. I will even trade the last 2 stars for a good fit!

Total confidence for commuting Ordered these in a size 30, they were drop shipped directly from Klim in Idaho. First impressions: heavy duty, stiff, and I'm not going to fit in them. Now keep in mind I'd just had a Chipolte barbacoa bowl for lunch prior to receiving these so my waistline was not in the best of shape. Fortunately I could just close the two button snaps at the waist, which then let me close the fly. I left the tags on and wore them for the rest of the work day, around 4 hours or so, at which point they had loosened up just enough to know that I would be keeping them. Tags cut, and mounted my 95 VFR750 for the ride home. Knee armor sits perfectly once feet are on the pegs, you can feel them initially but after a couple of minutes they adjust to my knees and the hardness is gone. I'm confident the armor would stay in place in an off, which is why I didn't go for the size 32 version, I've had other pants that were more of an overpant but the armor would never stay where it was needed, and sat too low on the leg. Temp was about 60F and could feel a good breeze on the upper thighs and gentle ventilation in the crotch. Gave me great peace of mind on the highway knowing I was no longer taking a risk with just my dress pants on. Currently using a Trailguard jacket with orange NP protectors, the Xergo stuff in the adventure line is definitely softer and more conforming. Are these pants worth $800? Hard to say, but my legs are important to me and these seem like the heaviest duty mesh pants on the market today. Rather stiff out of the box, looking forward to more comfort as they break in. Will be ordering the Gore-tex overpants for these shortly, to give full 4 season coverage. I was tempted to "save" by ordering the non mesh goretex adventure pants but wanted the mesh option for the hotter days. May 5, 2014
Hot weather gear 2 Day ride in SW California, from 59'F to 92'F. This is a great pant. I also have the Air Jacket. Great protection, great product. I am a normal 34 Jean size, got this in 36 size for an easy fit and possible layering for cold weather. April 21, 2014
