REI . Midweight Basic Layer Shirt
See, sometimes in the winter you just want to get dressed and keep going. If I have a whole day outside planned, go skiing, or, say, dread walking to work when it snows, I’ll pick up this base layer. This top fits great and provides warmth, stretch and good coverage from my neck to my roots.
For both women and men, the fit is very similar: crew-style around the neck, flat seams to prevent bunching or chafing, good sleeve length, and stitching around the shoulders (with the seams moving forward) so that the layer underneath runs a bundle. For women, it is designed more at the waist, while for men the top is cut straight.
It’s also worth noting that I’ve never really felt too hot in this top – I’ve tested it from minus 30 degrees Fahrenheit. If you feel warm or sweaty, the fabric is easily damaged.

REI . Medium Weight Base Layer Base
Base classes are for layering – but not just when skiing, snowboarding, or spending time outdoors. We found these base layer bottoms to be a great option for layering under lighter clamshell pants around town, too. If you’re in need of warmth and want a simple, budget-friendly, and durable option, these bottoms are just what you need.
Like any full-length pants, if you’re below average, you may find that the pants run too long. Bonus: For women, bottoms come in small sizes for this very reason! But other than that, many of our employees (of different heights and sizes) liked the fit of these bottoms. The waist has a fair amount of elastic, so you can wear it on your hips or higher depending on your preference.

Final notes: durability and style
All of the medium-weight base layers in the REI Co-op feature a striped or mottled pattern – which I love. Both men’s and women’s come in a few color options, and the lighter style gives the base layers a nicer look (unlike some solid color combinations I own, which are a much more straightforward long style). Basically, if you need to dress up for changing layers or something, I’m proud to rock these layers.
In the few years I’ve owned it, I’ve probably washed it more than 50 times. (I don’t wash after every wear, but I do wear them often, so it’s safe to say I lost count.) I never noticed any thinning spots, snags, or loose strands. Anyway, after several years, these base layers are still going strong, probably thanks to their synthetic fabric.
And we can’t leave without talking about the price. REI’s Medium Weight Base Layer Kit will get you up to $100—a pretty good deal for two large base layers.
