Jeff B.wrote a review of Fjallraven Keb Pant - Long - Men's on December 29, 2017
Familiarity: I've used it once or twice and have initial impressions
Fit: True to size
I'm 5'10", 184 lbs, have a 34.5" waist measurement and 40.5" hips/seat measurement (while wearing a pair of lightly insulated spandex-type tight). My inseam measures about 30.5" I selected "True to Size," but feel the need to qualify that statement.
Backcountry's size chart tells me that I should wear a EU50/US33-34". Using the sizing tool on the US Fjallraven website, it told me I should wear a 48/32". I typically wear a 32-33" waist (and 32" length with some stack or a 1.5" cuff at the bottom) in most jeans, but frequently have an issue with jeans being gappy at the waist and/or too tight in the butt/hips.
The EU48 / US32" version of the Keb pant fit me best with a note that they are a tad bit tight right at the entry of the hand pockets. The 33-34" was way too loose at the waist though. The length on the 32" is about the same as most 32" length jeans...so about right for my preference.
I also purchased the size 48 and 50 Vidda Pro trousers to try, as well. I noted that sizing is inconsistent between the Keb and Vidda Pro. The 48/32" in the Vidda Pro was too tight in the waist AND hips. The 50/33-34" size was too loose. I didn't keep either of the Vidda Pro, though they are a nice pant.
The last review point I'd like to make is regarding two design features on the Keb: the vents and the cuffs. Vents: I like this feature, but kind of wish that Fjallraven would include a mesh type fabric inside the vent like in the Lundhags pants I tried. Seems that it would be good to keep debris and bugs out...but having not used this feature yet, maybe it's irrelevant. Cuffs: Out of three different brands of pants and four different cuff systems, I think Fjallraven has the best, most durable system in the Keb and Vidda Pro trousers.
