The Best Arc’teryx Deals to Shop in September 2025

As much as we wish it weren’t true, summer is over. In an attempt to be proper adults, we’re being proactive and buying seasonal gear before we need it. Only a few weeks before, but we’re still trying to prep in advance. When this time of year comes around, we always turn to Arc’teryx. If it’s good enough for Frank Ocean and David Letterman—and actual mountain climbers—it’s good enough for us. Good thing REI’s sale section is stacked with dozens of the brand’s best-selling, high-performance jackets right now.

Our editors won’t stop singing their praises for the lineup at Arc’teryx, most of which is on sale at REI. The brand’s high-quality apparel is suited for all sorts of conditions and terrain, even if it’s just your daily slog to the office. Stay dry in the big city with the classic Beta rain shell, or invest in a heavier down style to stay warm in the mountains. Many of the brand’s lighter weight layering options are heavily discounted and we’re even seeing markdowns on shoes, like Kopek hiking boots and the editor-favorite Mantis backpack.

It’s easy to consider what you want to wear during the fall and winter months, but we’re talking about what you actually need when temperatures drop. Arc’teryx’s shells are essential for combatting the rain and wind that you’ll be battling all fall. There are two cons we’ll admit about Arc’teryx apparel and accessories: Products sell out fast and they’re expensive from the get go. Get yours soon.
