Patagonia, Arc’teryx and Columbia apparel is up to 50% off at REI — here’s 21 styles I’d shop for fall

These breathable, stretchy and comfortable leggings are perfect for just about any activity. They also have pockets that can fit everything from iPhones to snacks, and I know if I had these leggings, I'd be lounging in them more than I'd care to admit. Or, you know, working out in them. As you're supposed to.

There are nine colors sporting this discount, but I'm a personal fan of this stylish grey (called Asphalt Heather on the site) for its timeless look. With microventilated fabric, this tee is perfect for running, workouts and hitting the trails.

This is a classic basic fleece available in white, navy and black. Most sizes are still available in the navy and black. The Benton Springs fleece is ideal for everyday wear or less intense outdoor excursions. I would probably go for the navy color — it's an essential closet basic.

Not sure if you want to wear pants or shorts on your next hike? No problem! These versatile pants offer style, comfort — and removable legs. You can take them from hiking pants to shorts in just second thanks removable zip off legs. They're also quick drying and stretchy.

The Patagonia Better Sweater style is the ultimate comfort. These fleeces have the cozy vibe of an autumnal sweater but with the outdoor ruggedness of a Patagonia fleece. This is ideal for both wintry hikes and everyday errands. And the best part? It's still available in every single size other than XXS.

The North Face Alta Vista Rain Jacket is the kind of shell you’ll thank yourself for when the rain hits mid-hike or dog walk. It’s breathable, practical, and full of easy-access pockets. It looks great outdoors and just as good around town. I never travel without a waterproof jacket, and this one fits the bill perfectly.

This long-sleeve running tee is a popular pick from REI and while 9 colors are still full price, this teal fit is sporting a 31% discount. Using SwiftTex fabric to keep you cool, dry and unencumbered, it's an excellent pick for long runs especially on those cooler nights.

This is such a great closet staple. Ideal for layering during fall or winter hikes, the super-soft super-light base layer can be worn under fleeces and coats for more warmth. Or you could even wear it alone on those mild days. This shirt also has odor control and is quick drying. The 60+ 5-star ratings on REI speak for themselves, really.

The name of these shorts says it all! The Action Shorts are up for any adventure and allow you to stay cool, comfortable and dry while on the move thanks to their sweat-wicking and water-repellent properties. They also have an adjustable waistband and a split hem at the side seams for increased mobility.

This hoodie will be a closet staple for fall! Made with premium, soft fleece, the pullover offers a comfortable fit and is perfect for wearing any day of the week.

Whether you're on or off the trails, you'll want to be wearing these versatile pants. They'll keep you dry and comfortable thanks to their Flashdry material and durable water repellent finish.

A more streamlined take on the beloved Houdini jacket, the pullover variant skips the hood — making it a better option for joggers and cyclists — and features a half zipper rather. Like its sibling, the Houdini Stash 1/2-Zip Pullover is treated with a Durable Water Repellant (DWR) coating to keep you dry.

Designed with mountain climbers in mind, this handsome fitted hoody is ultra-breathable and stretchy. Made from Polartec Powder Dry Fleece, it also provides plenty of insulating power, despite weighing just under 8 ounces.

REI's own brand beanie wicks moisture and is breathable while also keeping you warm. It's 30% wool, but completely itch-free, making it the perfect versatile fall or winter hat!

This is the perfect headband for cold weather. The soft fabric will keep your ears warm and also make you look stylish! This headband actually has extra-long fibers, which help you stay warmer than ever.

If you want to wear the Patagonia logo proudly, this is the hat for you. This close-fitting, low-crown trucker hat has an organic cotton front, a recycled polyester mesh back and an adjustable snap closure.

Need some new gloves for the colder months ahead? These North Face gloves will keep you warm and toasty. They are super soft against the skin and feature a unique zigzag stitching pattern that helps create a better fit.

This is the ideal versatile beanie for fall and winter. As with the Coastal Cable hat above, the Brodeo Beanie is made from a recycled wool and recycled nylon blend, making it ultra-insulating and ultra-cozy. It's available in both brown (pictured) and green for just $34.

Featuring a timeless diamond shaped accent, this functional Herschel bag can hold your laptop among many other things. It also has a zippered exterior pocket and an internal media pocket with headphone port for added storage options.

This Columbia running shoe has a roomier fit, which is great for those with wide feet or feet that tend to expand during runs. The foam midsole and grippy outer sole makes the shoes ideal for road running in both wet and dry conditions.

This is the exact same shoe as the Konos running shoe above, but in women's sizes. This style is available in all sizes in three colors right now, including white (pictured), black, and gray.
