Not for me

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs large
  • Size Bought: 34

I felt like I was swimming in these pants. I like my pants more fitted. Not too thin, but definitely not this baggy.

Huge fan of ARC but these were a no for me

Durable pants

A great durable pant for any activity.

Great pants

  • Fit: True to size

I listened to "Fits Slightly Small" and bought a size up. I wear 33 waist, so I bought 34.
This thing runs little large on me (I can't wear without a belt). Later bought 32 and it fits great.

Wish side pocket was 1/2" wider

Great pants for hiking or climbing or casual stuff.

Good quality pants

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: 38x32

The legs are a bit wider than I expected. That's not a knock on the pants, but more of a warning for those who don't need it and don't like the look. The pants are light and pack small. I did worry about the belt loop. I tugged on one to pull up my pants and I heard a sound of fabric ripping...The rest of the pant is great.

My all-time favorite pants!

These are lightweight but durable and dry very quickly when they get wet. The relaxed fit is perfect for most activities and the rise is perfect without the crotch being too low or too snug. Highly recommend these pants!

I'm on my third pair. Mostly for casual hikes and knocking around, but they wear well, comfortable in most temps.

Great Product, Horrible Warranty service

    I love this pant, but..... The warranty through Arcteryx is expensive and timely. If you want a company that stands behind their product, and will help you out with repairs that don't cost as much as the initial product, I would recommend going with OR or Black Diamond.

    Or Patagonia

    Actually, I had a Theta AR jacket that didn't hold up. After about 5 years, some of the seams started coming part, and parts of the jacket started getting worn through. I sent it back asking for a quote, and they just sent me a brand new Theta AR that would have retailed for $575, without another word.

    Arcteryx replaced 2 torn pairs of pants for me with brand new pants without blinking an eye. Only requirement as I recall was that you need to return them within a year of buying them - so they might not replace them after 2 or 3 years..... but if you tear them within a year they replace them once you ship back the torn/broken ones.

    how do these fit compared to rampart pants?

    Best Answer

    Hey There,

    Both the Bastion and Rampart are going to be a relaxed fit and fit very similarly. Here is Arc'Teryx's size chart for reference

    If you have any more questions about pants or gear, please give me a call at 1-800-409-4502 ext 4446 or email at

    Geoff is write, both of these pants feature a Relaxed fit block. One of the biggest differences will be the type of material each pant is constructed with. The Ramparts are constructed with Terraxtex, a Nylon/Spandex blend while the Bastions are constructed with Cotton/Nylon blend. While both fabrics are durable the Ramparts will have slightly more abrasion resistance and some stretch. The Bastions are durable and will have a softer hand.

    Stephen, don't you mean Geoff is Right?

    Grant, don't you mean that Stephen means that Geoff is right?

    Paul, did you mean for your post to be a question to Grant about Stephen and Geoff, or was that supposed to be a statement?

    this is pure garbage. the button fell off after the first day. great for emasculated males because there is no room in the crotch or rear

    what a joke

    might be good for skeletons

    amb - fortunately you're covered by both and Arc'teryx on this one. will accept a return or exchange it for the proper size. Arc'teryx would be more than happy to warranty these.

    Please note the sizing chart, some very helpful information there.

    I would say they fit true to size if you're in shape. I wear a 30 waist jeans and the 30 Bastions fit perfectly. It's not so much that these are for skeletons, they're just not designed for Wrangler wearing landwhales.

    Great travel pant.

    • Fit: True to size

    I take these with me when we travel and for just knocking around while at home. They are very comfortable and they are also very durable.

    I thought I would write an update on this pant.

    The material has changed. The past ones I have had were much thicker and I would say they seemed much more of a cotton canvas material.

    These new ones are much thinner and you can tell they scrimped on the quality just a bit.

    Imagine a great product that the Chinese tried to make a knockoff of. Oh yeah, that is what happened. For a Chinese made pant they are pretty cool. Thanks for selling your soul to the Chinese Devil Arc'teryx

    love these pants

    These pants are super comfortable and fit great. Very versatile temperature-wise. Like all Arc Teryx stuff they probably won't fit well if you don't have a trim/athletic build. Great for travel, lounging, hiking, camping, low impact stuff. I don't recommend them for heavy activity that requires full range of motion -- the fit is snug (but comfortable) in the groin area.

    great pants

      Great fit and length. Light enough for warm weather. Super comfy for traveling. Definitely buying a second pair.

      Here we go again

        So I have to say these are one of the best fitting pants I have ever bought. They are not too tight (and also not to baggy), the length is a solid 32 inches in the 30 inch waist, and the waist fits me perfect. When moving in them I can make dynamic movements with the legs, the gusseted crotch gives you a lot more freedom of movement. This pant is a lot thinner than many outdoor manufacturer pants and they are super cush for hanging out or a day on the boulder. I have a 32.5 inch waist. I usually have to buy size 32 inch pants, but these run very big so I had to size down to the 30 which laying flat measures 16.5 inches in the pair I have. To the review below, if the size you got was too tight, size up. I usually have to try a couple different sizes before I find the right one. That was definitely not my experience, I find these run big so I suggest size down 1 size. The color is right on for the peat, but I think the graphite is a little darker than the picture on here. I have both colors and love them, these pants are bomb, highly recommended.

        Talk about tight.

          I put them on and I felt like someone grabbed a hold of my *use your imagination* and held on tight. Sitting down was a tough process and doing anything involved movement was difficult. I did not buy a size too small, I actually bought a size larger because I have a few friends who own Arc'teryx pants and told me to get one size bigger. If I had purchased the exact size I wear in jeans I probably would not have even been able to put them on.

          Unless you are a bike messenger or someone who enjoys extremely tight fitting pants around the crotch area, and by extremely tight fitting I mean cutting off blood flow, then stay away.

          Maybe they should say in the specifications or description that they wear extremely tight and someone who bought them, like me, would not have to comment on their PERSONAL EXPERIENCE on ownership. I own many high-end pants and these were absolutely nothing to write home about, stay away.

          Why wouldn't you size up if the size you were trying to wear was too tight? I have these and they are one of the best fitting pants i have ever bought in my life.

          I have to say, the cut of these pants are very specific to body types. If you have pronounced hips and tree trunk thighs, then these aren't ideal.

          The other option is to size up and use a belt. I usually wear 34, these are tight around the hips at 34, 36 will probably fit fine but out of stock when I try them.
