The Arc'teryx Men's Bastion Pant is a canvas pant for serious work. The mid-weight canvas is comprised of a cotton/nylon blend, providing the durability and comfort you'll need to work on the car, chop wood, and just finish up those general outdoor chores without wrecking your good jeans. Articulated patterning throughout with special attention paid to articulation in the knees and seat allow you to stand, walk, crouch down and move with general ease. The standard 5-pocket configuration keeps wallet, keys and random tools close by. Belt loops are belt-ready so the pants stay right where you want them throughout the day.

FEATURES of the Arcteryx Men's Bastion Pant

  • Articulated knees, gusseted crotch for mobility and comfort
  • Classic 5-pockets as well as accessory pocket on leg
  • Embroidered bird logo
  • Riveted stress points for added durability
  • Front fly with button closure

Rated 4 out of 5 by from Awesome in the Heat I bought these in the USA and very shortly after moved to South India. In the Summer. Temperatures here reach in excess of 40 degrees Celsius. I have to say these pants are probably the most comfortable pants I have ever owned! I'm really particular on the kind of trousers I wear, and these justify the cost. They are comfortable in muggy hot environments. The fabric is thin and probably best suited to warmer climates. They are lightweight which is ideal for a day in the office or out and about in the field. They are spacious and fit comfortably. The length is generous and as with most American bought trousers I have to have them taken up and hemmed. I would recommend them for comfort in the field on a hot day.

Rated 2 out of 5 by from Bummer I've been wearing these pants for years. Just order three new pair. The new version of this pant fits very large in every way and now uses a lighter almost dress slack type fabric and the very nice detail of a felt lined inner waste band has been omitted as well. If you are coming to these pants with no expectations, they might be OK. Having owned and loved dozens of the past generation of this pant this new version disappoints on almost every level. I will be reordering a size down to see if the fit is more inline with the original sizing. If it is and I keep them I will follow up with another review. Maybe I'll grow to love the new version, or maybe the first Bastion will be like my first love - the high mark that all others have since been compared to. - Sad in Cascadia

Rated 5 out of 5 by from My Favorite Pants Extremely comfortable pair pants with a very nice straight-leg relaxed cut. They are very comfortable for a number of activities and even if not a technical piece of clothing, they can be used for climbing or easy hikes in warm weather conditions. Even if the gusseted crotch and articulated knees allow moving freely, I'd still like to see a small amount of elasten added to the excellent cotton-nylon blend for extra stretch and so that the pants keep their shape even if wet or after a couple of days of use. Hoping to see them in Admiral 2016. Overall I can highly recommend these pants.

Rated 5 out of 5 by from The best pants for any outdoor activity. These are my favorite pants because they are comfortable, very durable, and temperature regulated. I have used them while hiking, mountain biking, climbing, and around town. The fabric is really great because it is soft, durable, cool in the summer, but also warm in the southwest winters. I like them so much that I bought a second pair. You get what you pay for with these pants.

Rated 4 out of 5 by from Improper Pantsing - but still delivers Love the material, love the feel, love the features of these pants. Relatively thin and breathable in the heat. Comfy hand. Unfortunately, there's seems to be 2 types of Arcteryx pants, those that fit great, and those that have a mysteriously constricted pelvic envelopment. These unfortunately fall in the latter category, so I had to size up to a 32 waist, which is slightly loose and I definitely need a belt. Other Arc' models like the Rampart and Gamma LT fit great in 30 (also their ski pants in small like the Stingray). But the Bastion, Palisades, Perimeters, and Stowe are all either too lose or too tight, not just right. Both of those groups contain both Relaxed and Athletic fit, so that doesn't explain it. (Rampart and Bastion are both Relaxed.) They are also slightly longer than the other pants, but this seems true to size. Pants like the Rampart fit me well in 32 inseam (Arc's regular pant length), even though my inseam is 30. These seem longer in 32, they drag in bare feet, which works in this casual pant. So in length they appear more accurate. Perhaps I have unusual proportions. Otherwise, they feel great.

Rated 5 out of 5 by from Great All-Rounder Ordered 28-30, the waist is a little large even at 28, but it's very comfortable. The articulated knees and gusseted crotch work really work for even climbing when making some high steps. I liked these enough to purchase them both in Graphite and Peat and both are simple and stylish.

Rated 5 out of 5 by from My favourite pants These pants wear well, and fit me great. I have relatively large legs and there is sufficient room in the legs of the pants to provide good mobility for outdoor activities. I will continue to buy these pants as long as arcteryx makes them.

Chest / Bust - Measure around your chest / bust, holding the measuring tape under your armpit.

Waist - Measure around the natural waist, which is often the narrowest part of your waist.

Hip - Measure around your hips at the widest part.

Sleeve Length - With your arms in a slightly bent position, measure from the center of the back of your neck, along the length of your arm, to the wrist.

Inseam / Pant Length - From a standing position, measure from your crotch to your ankle.

Head Circumference - Measure the full circumference around the widest part of your head.

Hand Length - Measure from the tip of your middle finger to the base of the palm.

Hand Width - Measure the circumference of your hand around the knuckles, excluding the thumb.

• Please note that all the info provided above refers to body measurements, and NOT the dimensions of the garment.


Next to Skin Fit - These snugly-fitting garments are made with stretch fabrics to fit next to the skin to enhance moisture management and thermal efficiency. Garments in this fit category when constructed using Arc'teryx's heavier-weight AR and SV fabrics also perform very well as mid layer pieces, and users should consider selecting a larger size to accommodate a base layer underneath if the intention is to use this layering system as a mid layer option.

Trim Fit - Trim-fitted garments share the motion-friendly traits with Arc'teryx "Athletic" fit garments, but are patterned with lower volume for reduced bulk. These close-fitting pieces layer well under other garments.

Athletic Fit - This is the "Arc'teryx Standard" fit. These complete patterns utilize anatomical shaping and gussets to enhance motion by minimizing excess bulk. Easy layering under or over each item extends seasonal versatility and comfort.

Relaxed Fit - Relaxed fit garments rely on higher volume patterns and a reduced amount of articulation to offer roomy mobility.

Expedition Fit - Cut roomier than the Arc'teryx Athletic fit and suitable for winter/extreme conditions, Expedition (XPD) fit garments are cut larger to accommodate multiple layers without binding or restricting movement.

• You can find the fit type and additional fit info for Arc'teryx styles in the product description FEATURES and SPECIFICATIONS.
