DYNAMIC SEAM PLACEMENT
LONG LASTING PERFORMANCE MEETS FREEDOM TO MOVE.
Get ready to bust a move — not a seam.
Our dynamic seam placements utilize biomechanical data from athletes to strengthen high-wear areas and improve your natural range of motion.

IT’S OUR PHILOSOPHY
We watch athletes in the field, we have them use our gear in extreme conditions, we get feedback, we repeat.
By optimizing where every seam goes, we’re maximizing movement and joint articulation while delivering a minimalist product that’s refined down to the seams that matter.
MOVE WITHOUT LIMITS.
Less is always more when it comes to moving through the mountains. Precise, strategic and athlete tested — every seam placement improves your performance by allowing you to move without resistance.

HEAD, SHOULDERS, KNEES AND TOES…
“From gussets to shoulders to hood, we’re driven by an obsession with how you move in the mountains,” says designer Greg Grenzke.
That’s why dynamic seam placement leads our design ethos. We make gear that’s a part of you — we dream of la piece de no resistance.





MOVING WITH YOU SINCE THE BEGINNING
We know where the pressure builds when you move. Our dynamic seam placements ease tension, helping your gear break in…not down.

CHANGING THE FUTURE OF MOUNTAIN APPAREL WITH A LOOK ALL OUR OWN.


Undeniably recognizable, our dynamic seam placements are informed by mountain athletes who need to move unhindered. No restraints — just a whole lot of wild abandon.
“Of course, it looks good, but it’s not frivolous,” says designer Greg Grenzke. Every seam is driven by function and designed to “optimize how you move,” he says.
THE REAL TEST IS OUT IN THE FIELD
Whether you’re mid-crux, leaping over a crevasse, or finishing a run, “any sense of resistance is a bad sign,” says Arc’teryx designer Tom Fayle.
That’s why we obsess dynamic seam placements — to keep you moving freely.



“When I’m ice climbing and mid crux, all my focus goes into the movements I’m making to keep me safe and in control,” says Arc’teryx athlete Sarah Hueniken. “The best gear is the gear I don’t notice,” she says. “And dynamic seam placement lets me stay present and move freely without concern.”
EVERY SEAM HAS A PURPOSE
