Prime Day who? REI's Patagonia sale is all I care about right now — 21 hand-picked deals from $15

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.

Hip packs are so underrated, and perfect for both day hikes and running errands in the city. The Patagonia Terravia hip pack is large enough to fit a phone, snacks, and more, which makes it an ideal versatile choice. Right now you can grab it for just $23 in this gorgeous pink color.

The Patagonia Powder Town range is perfect for skiing and winter sports, and the Powder Town Beanie is no different. This uber-warm bobble beanie hat will keep you warm in the snow thanks to its insulating fabric (that even works when wet!).

This green shade might be on clearance, but trucker hats never go out of style, so I'm sure this will look fresh even next summer. Thanks to the mesh panel, this hat will keep you cool and shady in the summertime, and the brim is made of recycled fishing nets. There's only one colorway discounted right now.

The Patagonia Powder Town Headband is designed to keep your ears warm on the slopes, without overheating the rest of you. It's also so bright that your friends will always be able to find you. This headband has a moisture-wicking recycled fleece lining to keep you dry and cozy.

One of my favorite things about Patagonia apparel is that it's so versatile. These corduroy pants are no different. Thanks to the organic cotton fabric and elastic waistband, these pants are super comfortable. They can also be worn dressed up or down, which makes them ideal for day trips, running errands, or even date night. Wearers claim that they run a little small, so recommend sizing up. These pants are only available in a size 6 and 8 right now, so I'd be quick if that's your size.

While this t-shirt is on sale in both mauve and blue, it's only available in XL and XXL sizes — and at this awesome 25% discount, I'm not sure how long either size will last. Patagonia's "Responsibili-Tee" shirts are made from recycled cotton and polyester, so it's definitely a shirt for the eco-conscious out there. Personally, I love the pictured mauve shade, but the stormy blue shade is beautiful too.

Made with recycled wool and recycled nylon, the Patagonia Coastal Cable beanie is super-warm and super-fuzzy, perfect for winter and fall. There's even a recycled fleece headband to keep the cold out and the warm in. The green color is eye-catching enough to ensure your friends will never lose you on the slopes or in the city.

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.

This T-shirt is cooling, quick-dying, and stretchy, so it's the ultimate comfy shirt for outdoor activities. It has moisture-wicking and odor-controlling fabric, which makes it ideal for watersports and sweaty hikes. Right now you can get it in pink or blue on discount — there are more sizes available in blue.

This hat is the perfect combination of function and style. The sale is live in all three colors: black/multi (pictured), white/green, green/teal, and I think all styles are gorgeous. I have a soft spot for this black one, but all three are lovely. Style aside, the hat itself has a moisture-wicking fleece lining and is made from recycled wool and polyester.

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. But the best part? Thumb. Holes.

This super-soft jersey long-sleeved shirt has a throwback Patagonia logo — gone is the usual mountainscape. Here you'll find the original logo Patagonia wearers used to sew onto their backpacks in 1973. How cool is that?

On top of being a throwback, this shirt is made from recycled plastic water bottles, so you know your money is going to a good place. It's available in blue and red, although more sizes are available in blue.

This capilene layering top is thick enough to be worn alone on a mild day, or under a fleece and jacket on a cold day. It's available in blue and orange and most sizes are in stock. This shirt has 48 5-star ratings, and reviewers love how fast it dries.

This bag can be worn two ways: either as a backpack or a tote bag. It's ideal for those days when you've got the office at 5 but the trails at 6. Reviewers say it's ultralight and roomy inside, but it's a little pricey for what it is. Good thing it's on sale for just $68, then!

This is the perfect everday lounging jumpsuit. It's completely wrinkle-free, so you can toss it in a backpack for post-hike hangouts. It's also comfy and stretchy, quick-drying, and has pockets! Reviewers note that the fit has changed from the previous version, so maybe check measurements if you're used to the original fit.

Although they look like sweatpants, the Patagonia Outdoor Everyday Pants are ideal for hikes and outdoor activities. As they're wide-legged, they're super comfortable, and are even water-repellant. They're on sale in both lilac (pictured) and black.

I assume Synchilla fleeces are named as such because they're so soft. If you've never touched one, it's like how I imagine touching a chinchilla is. The fabric is cloud-soft and keeps you warm in the fall and winter. This fleece is on sale in five colorways and most sizes are still available, so hopefully you'll be able to find one that suits your tastes.

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.

I have a Torrentshell jacket, and I love it with all my heart. A small part of me actually looks forward to rainy warm days so I can wear it — don't tell anyone. The water literally slides right off the waterproof shell and there are underarm zips for ultimate breathability. Right now it's on sale for less than $100 in yellow in two sizes.

This is the exact same fleece as the men's Synchilla above, so rest assured the women's version has the same silky soft fabric. This is such a versatile fleece, ideal for both outdoor adventures and everyday activities, especially when it's $30 off. The Synchilla is available in the pictured blue-and-brown pattern and a beautiful terracotta pink shade. There are still sizes M-XL available, but hurry!
