Venechukwrote a review of Prana Brion Pant - Men's on September 19, 2017
Familiarity: I've used it several times
Fit: True to size
I love these pants, they're super comfortable and look great. I have two pair: charcoal and dark ginger. They're a nice alternative to chinos and a cooler choice on a hot day when you don't want to wear jeans. The stretch Zion fabric breathes well and stretches so you can wear these straight from work to a hike to dinner, no joke. Great for travel too, as they don't wrinkle easily and they don't look like your typical 'travel pants.' Prana knocked it out of the park with these, I really don't have anything I'd change. I have a couple pair of the shorts as well and they're just as great.
On sizing, these are 'slim,' which does not mean skinny or tapered. Straight from the knee to the ankle, but a nice trim fit. If you're a quadzilla these will be snug but I'm pretty athletic and no issues. I found these to run about one number size smaller than the Stretch Zions in the waist, and one size longer in the inseam. I typically get a 32x24 in the Zions and got a 33x32 in these and they fit perfectly.
