REI's anti-Prime Day sale is heating up — I'm obsessed with these Columbia deals from just $16

The Columbia Bundle Up Beanie has luxurious sherpa fleece lining, which makes it the perfect choice for winter. The beanie is available in both purple and green (pictured), so you'll be sure to find a style that suits you.

This windbreaker is rated UPF 50, which makes it an essential addition to your spring, summer, or transitional closet. This is the perfect lightweight jacket to throw over a fleece during mild weather or wear with just a T-shirt in hot weather when you want to keep the sun off you. It's only available in XL and XXL, so hurry!

This super lightweight hoodie is less of a keep-warm product and more of a keep-the-sun-off-me product. It's ideal for outdoor adventures during the summer when you want to protect your skin with something breathable. It's even got UPF 40. And the best part? It's got thumb holes.

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

No, that's not a typo. Yes, this jacket is nearly $100 off right now. There are only a few sizes left in the gorgeous plum color (pictured) and the black colorway, so I'd grab this before it's out of stock forever. The Pike Lake II jacket has thermal-reflective technology designed to keep you warm and is made from 100% recycled polyester.

This utilitarian jacket is perfect for fall thanks to the thick-yet-lightweight material. There's a D-ring for ultimate functionality — you could attach your phone or keys to the front of the jacket should you so desire. As it's a casual shirt, this isn't the right piece to wear hiking, but it'd look great at the post-hike hangout. It's discounted in all three colors; black (pictured), cream, and green.

How gorgeous is that color? And the price is, of course, even more gorgeous. The Boulder Falls waterproof jacket is still available in most sizes, so I'd definitely grab this awesome rain jacket before it sells out. It has underarm zips so is ultra-breathable, and has Columbia's trademarked OmniTech waterproofing.

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.
