In 1989, in North Vancouver, a climber named Dave Lane started a company called Rock Solid. He was sewing climbing gear in his basement and selling it to other climbers, and in 1991 the company was renamed Arc'teryx, after the Archaeopteryx, the fossil that sits between early dinosaurs and birds. That fossil is still the logo on every chest and pack. Not bad for a basement.

I like the brand best when it is not the jacket. Jeremy Guard, who chose the name, wanted it to stand for accelerating evolution, and you can see that in how the brand keeps taking one clever idea, like the heat-laminated Vapor harness of 1993, and stretching it across a pack, then a shell, then a fleece. Amer Sports has owned it since 2005. This edit is the quieter end of the catalog: layers, packs, hats and shoes, with the shell jackets left to their own edit.

Fleece is where I would begin in October. The Kyanite Hoody in Moondrop is a plum hooded fleece with a nylon face and a brushed interior, and the brand says it works as a midlayer or on its own. The Covert Cardigan in Arc Silk Heather/Salt is the cream, open-front one I would throw over a plain tee, and the Covert Half-Zip in Black Heather is the charcoal one for walking the dog. The Emblem Fleece Crew in black keeps the bird down to a small chest logo.

For the cold mornings, the Atom Insulated Vest in Bracken adds stretch fleece side panels and an olive-gold color that works with denim. The black Atom Vest has Coreloft insulation and a stand collar. Tip: zip any of these to the chin and lift your arms overhead. If the hem rides up past your waistband, size up.

The brand describes the Mantis as a pack with organization, durability and balanced carry in a clean, minimalist design, and that is why it turns up on commutes and in carry-on queues as much as on trails. The Mantis 26 in Dark Jade/Mongoose is the green 26-liter daypack with a padded back panel, the one I would load for a weekend away. The two Mantis 16 packs, in Black and in Kasumi/Blirple, are the same idea in a smaller 16-liter size, and the lavender one is the easiest way to add color to a gray coat.

For hands-free days, the Mantis 2 Waist Pack in Renegade is a raspberry sling you can wear across the body or at the waist. The Mantis 1 in 24K Black is the compact version with a gold bird logo and zip pockets, which is plenty for a phone, keys and a lip balm. The Heliad Crossbody in Mallow is a lilac, ultralight rectangle, and I would carry it with a black fleece. The Granville 25 in Dk Stratus is slate blue and shaped for commuting, while the Konseal 15 in Nucleus is a bright yellow minimalist pack.

Before you buy, load your real things in it: laptop, water bottle, a book. Then check that the straps sit flat on a coat and that the zip pulls are easy to grab with a glove on.

What I would skip: the two waist packs if you carry a bottle and a book every day. Take the Mantis 26 instead.

The brand added technical apparel in 1996, once it had licenses to use Gore-Tex, and the base layers are the quiet descendants of that move. They are the pieces you wear under everything and rarely photograph. The Sunna Speed Bird Crew in black is a light, quick-drying tee with a small bird graphic. The Rho Zip Neck in Mongoose is a brown, fitted, fleece-lined quarter-zip, and the Rho Crew in black is the microfleece version with thumb loops that I would pull on under a puffer vest.

For merino, the Satoro Crew in Tatsu is an olive green long-sleeve with a fitted cut, and the Hallam Merino Hoody in Bliss is a pink trim-fit hoody with a low-profile hood that fits under a helmet. The Rula Long-Sleeve in Light Renegade/Renegade is a pink, soft mock-neck climbing shirt, and the Olera Zip Neck in Kasumi is a periwinkle mid layer with a smooth face and hollow-core fleece. These are fitted on purpose, so they layer without bunching.

The test I use: lift your arms and check that the neck sits flat and the sleeves still reach your wrists. Then stand in front of a window. If you can see too much through the fabric, wear it as an under layer, not on its own.

What I would skip: the white Kragg Cotton Bird Crew for anything sweaty. It is a heavyweight cotton tee, so keep it for the city.

The brand's move toward city clothes has a date: Veilance, the line aimed at urban dressing, was founded in 2009. You can feel that thinking in the pants here, which look like trousers and still carry the technical fabric. The Gamma Pants in Moondrop are plum soft shell with wind protection and stretch. The Gamma MX Straight Leg in Canvas is the tan, straight-leg, winter-hike version with a PFAS-free water repellent finish.

The Leutia in Sea Salt is a cream, relaxed wide-leg pant in lightweight soft shell, and the Nia in Canvas is the tan wide-leg that shrugs off wind and brambles. For something that reads as a regular trouser, the Clarkia Cotton Wide-Leg in Mongoose is a brown heavyweight cotton-nylon blend. I would pair it with the Rho Crew and a chunky boot.

Closer to the body, the Essent High-Rise Utility Legging in Black has stretch nylon and utility pockets, the Rho Base Layer Bottoms in Black are fleece-lined, and the Emblem Fleece Joggers in Black are tapered with cuffed ankles.

At the fitting stage, sit all the way down and check the rise, then bend and check the hem over your boots. Wide legs need a shoe with some weight.

What I would skip: the Rho bottoms as stand-alone leggings. They are made to sit under pants.

Walk through Midtown or SoHo in October and you will see the proof: Vogue noted dinosaur fossil-logoed beanies on New Yorkers' heads. The Bird Word Toque in Orca is the white knit with the big black wordmark and bird, and the Satoro Merino Toque in Black/Arctic Silk is the reversible one that stays low under a helmet. Both are an easy way to wear the logo without a jacket.

The caps and bucket cover the rest of the year. The Sinsolo Bucket Hat in Moon Drop is a purple, stretchy hat with a built-in chin cord, the Bird Word Cap in Cosmic Bloom is a cream six-panel with a pink brim, and the Gamma 5-Panel Cap in Mallow is a lilac soft shell cap. The Venta Gloves in Black are stretch soft shell with a high-loft fleece lining, using GORE-TEX INFINIUM fabric to block wind.

On shoes, Vogue reported that the brand is doubling down on footwear, and that its shoes are built for trail, not road running. The Kragg Shoes in Moondrop Ct/Black are a lilac pull-on camp shoe with a woven mesh upper, and the Kragg Aura in Black/Black is the ventilated slip-on.

Try the gloves with your phone in hand, and flex the hat over your ears before you commit.

What I would skip: the Kragg Aura on cold, wet days. Its open-system upper is made for airflow.

I would pick in this order. First the Kyanite Hoody or a Covert piece, because fleece does the most work from now until March. Then the Mantis 26 if you carry a laptop, or the Mantis 1 if you do not.

Last, add a toque. It is the quickest way into the brand's look, and the bird logo does the talking.

It is funny that a company that began with a climber sewing harnesses in a basement now has its fossil on the fronts of fleeces and the sides of commuter packs. The bird made it down from the mountain.
