RHO LT BOTTOM Arc'teryx - Pantalon Running | Distance BLACK / S/1

These base layers are a great product. The fit is amazing: close without being constrictive. The fabric is soft, without compromising durability or trustworthiness. I didn't think I needed the cargo pocket, but honestly it's been handy to have while scooting around in only base layers. You can feel the zipper buried under your pants, but its worth it for expanded usability. I've only worn these during low-output activities (sleep clothes for cold camping and post-sierra backpacking outings) and they serve well for this purpose. I run hot, so am unlikely to take them on cold weather trail runs, but I see no reason why they wouldn't be great for my cold brethren. So good job Arc'teryx. Another great product.

These are wonderfully lightweight and comfortable! I was able to wear these all day under a pair of jeans while out hunting some Grouse on the 4-wheeler and didn’t feel like I was anywhere close to over heating!Took them out for a jog and my legs weren’t cold at all. I do appreciate the small pocket being on the thigh. I was able to toss my ID and some cash in there without it flying away. The leg is a little long but I can appreciate that when wearing my cold weather socks that I pulled right up over the leg and they didn’t feel bunched up.I will definitely go buy another pair just to wear around the house.

Nice warm product but definitely fits larger than expected. I ordered a size small and and compared to other products I’ve used in the past it fits like a large.

Out of the box, these are top notch, soft to the feel, seams placed out of the way so no chafing, warm and they are in between the fit of joggers and actual tights - see pics attached. I used them first time out for hiking on the trail, where it was low 40's temperature. I know they are made to be used as a base layer, but there will not be any snow in Maryland until the winter. For sure then I am looking forward to placing them underneath as a base layer for snow sports. I will also plan on running in them when the temperatures dip below freezing. There is one pocket on the right outer thigh, was hoping this would be large enough for a cell phone, but its only good for a few credit cards/ID and cash, maybe a car key and chapstick or a granola bar and energy gel.
