Brion Pant is Nigh Unto Unicorn Skin
I was given my first pair of Prana Brion pants. At first grasp, I enjoyed the delicately durable material. It took me back to the early days of my past life, where I worked as a woodworker in a small viking village. We routinely caught and skinned a now endangered species of Unicorn strictly for their unbelievably comfortable hide which we would then fashion into the highest quality of viking apparel. It was warm and soft. It caressed the skin. It protected you. It loved you. As I pulled the Brion pant up my bare past life and my current life overlapped briefly as the warmth of this modern day Unicorn skin overcame me. I was once again engulfed in the protection of the material that I once held so dear. I wear a different color of this pant everyday. No lower extremity body wear can claim equality to the Brion. This is truly a piece of clothing fit for the King of the Vikings.

Nice pant
I like these pants they way the fit and are very comfortable. But, you need to offer more colors like khaki, light grey, medium grey, chino, etc.

If I didn't buy these...he'd be naked.
So I'm 3 miles deep in a hike through the mountains of the Cascade Mountian range and my better half if I can call him that lol sees a rock face. Of course he climbed in college I mean that's only forever ago and totally normal for the PNW. Anyhow he says it's fine cause I'm wearing my PrAna Brion pants they are for yoga (gets into his warrior 2 stance to make sure I know). He takes his launch hold and dyno's up to face of the rock. I stand there thinking no way did this day start with him dancing around naked saying I need to go to work then I want to hike and what am I going to wear.

He literally wore his PrAna Brion pants with a casual dress shirt through his day of corporate work into the woods to successfully dyno a rock face.

He gets down, and says...these pants are basically like being naked.

Ps. When I went to rei- the service rep said and I quote, " 9 out of 10 employees wear these everyday".

Brion pant is great
Best pants I've ever worn. Like a favorite pair of jeans on the first wear. I now have 5 different colors after they just added dark khaki again to their fall line. I'm typically stingy and don't want to spend high $ on casual pants but these are worth it. Better than anything similar which Patagonia or anyone else has put out and I'm a big Patagonia fan. Never need ironing, never seem to age or fade, and look good in anything from a dress shirt to a t-shirt and flip flops. I wear them in Alabama in the summer and they are still comfortable. Every friend I've told about these who has tried them has loved them. Can't find them on sale anymore, but still worth the price tag.

Great casual pants
These pants are pretty darn nice. I love the material and the fit. I do wish the legs had a bit more of a taper to them but this is just a personal preference and not something to ding the pants on. (Prana, if you are reading these, take the aesthetic of the Brion and the fit of the Wyatt and I will buy a pair in every color.) The looks and the performance fabric mean that these pants can transition from doing something active to going out to dinner without skipping a beat.

From work to the crag! Best Pants ever!
The Brion pant by prana has so many uses. I wear khaki, black, and the blue alnernating every day of the week. Having these pants, and being very active always me not to have 2 sets of clothes when I head from school to the climbing gym. The flexibility gives me comfort throughout the day while in class learning, or walking to and from the lab. I recommend these pants for anyone who has a really skinny body, who is tall, but is looking for a pant that fits their hips, and needs proportionate fit to even out the rest of the body. HAPPY TRAILS!!!

From Trail to Conference Room
Brions are pretty much my go-to pants on the daily. I commute to work via single speed and these guys have held up to some serious abuse.

They are extremely comfortable and slim fitting, however you can throw a thermal compression base layer underneath. Personally, I am comfortable down to about 8ºF on my rides. Keep in mind they are thin, so for me I wear them year round no problem.

They look good in trainers, urban SPDs, as well as dress shoes. I have had many compliments on their fit. Wash cold on a gentle cycle and hang dry and and these pants will last you for years. They have for me.

Pant is great, but can be even greater!
I love the Bryon pant but it can be even better.
1) The waist band area can use just a little more structure. the top of the zipper area gaps open and overall the pant material is too thin and light in this area.
2) The pant does not look young and hip enough due to the pant leg being too wide. Due to the fabric's lightweight stretchy structure, which I love, I would like the leg to be more narrow. The pant would look better and there would be less material flapping around.
In Black, I feel like I'm wearing dress pants, when if the leg were more narrow, I'd feel more casual and youthful.
3) I tried to roll up (cuff) the pant leg, but due to the light weight fabric the pant leg won't roll nicely. Also the leg opening is too wide to roll the bottom and make it look young. It's too wide.
4) More colors, more colors, more colors please! Please offer a Navy or denim, Green, and two Khaki colors (not just one).
5) I'd offer another version of this exact pant with a cargo pocket on the right pant leg.

This pant is special. I love the fabric and it's all I wear when traveling. But the pant needs to look more youthful with a narrower leg and more colors, please. Thanks for listening.

Favorite Pants.
I've had a pair for 2 years now, wearing them regularly, and they look good as new. I'm actually returning to the site to get more(other pants (I think american eagle?) have worn, torn and been tossed). I've worn these pants climbing, hiking, out to the bars, to church, even to a job interview. More colors would be nice.

By far my favorite pants
I have four pairs of these pants and I wear them nearly every day. There lightweight, very comfortable and with a more tailored look very easy to dress up or down. I recommend these pants to every guy I know.
