The weather has turned pretty chilly, and I find myself reaching for fleece-lined everything (or, ya know, actual fleece).
It’s amazing how much warmer fleece-lined leggings are than jeans, and whether I’m headed outside for an actual run or just running Pax to school…fleece-lined leggings have become an easy win.

So when Under Armour reached out and asked to work together, I knew I was going to start with its base layers — we’ve been fans for years. But once I discovered that Under Armour also has fleece-lined leggings in some seriously gorgeous colors, I was thrilled.
Fleece-Lined Leggings + Sweatpants We Never Want To Take Off: Under Armour
I first discovered how cozy Under Armour clothing could be on our trip to Iceland. We went when the boys were much younger — roughly one billion years ago by my latest, post-COVID calculations — and had a blast hiking and exploring. I’d packed a couple of pairs of Under Armour sweats (and matching hoodies) for each kid, and I was pleasantly surprised by how well they performed.
I don’t often think of sweatpants as a technical performance piece, but those Under Armour sweats seemed to do a better job of blocking wind than typical, old-school sweatpants, and — caveat: This was a long time ago — they ended up being a little water-resistant as well.
My kids’ exact sweatpants are obviously long gone, but Under Armour’s Armour Fleece looks and feels a lot like those old sweatpants. And since we’re going to be spending a good part of our winter in the north (Upper Pennisula of Michigan and Northern Vermont, here we come), I figured the boys could use a similar pair.
And by “boys,” Mike figured I meant him as well.

And OK, fine: He is the guy heading out at 6 a.m. to shovel the driveway before driving the boys to school so…

Truth be told, Mike wasn’t totally convinced at first feel. These Armour Fleece Twist Pants look a heck of a lot like old-school sweatpants (arguably wayyyyy more flattering), but they do feel like a stretchier performance knit, which I think surprised him.
Once he had these fleece-lined sweatpants on, though, the man was sold. They’re also available in regular or tall sizes, too.

Under Armour’s Fleece-Lined Leggings + A Matching Jacket For Me
Now, let’s talk about those Under Armour Train Cold Weather Full-Length Leggings. The waist is nice and high, they’re supportive without being squeezy, and they’re available in three lengths: short, regular and long. I’m wearing the regular because I like them long once I start running outside in the cold (but I do have them turned them under in the photos). The fit is TTS.
AND….there’s a matching jacket (I mean, seriously — that color!!!) with thumbholes.

Lastly, if you haven’t yet tried Under Armour’s HOVR line, these Phantom 3 Metallic Running Shoes have some serious cushion, don’t require socks (at least not for me), and have more arch support than most running shoes I’ve tried. They’re also really pretty.

I’ve found that once I get the laces set properly, I can then just sneak my foot in and out without untying them.

In summary? Fleece-lined everything. My sanity-savers for these long winter months.
Cheers to staying active in the cold, gang.
