super warm and well fitting, I love them

I first bought the light-weight leggings and t-shirt through REI and didn't take them off for a week! Bought this thicker pair to wear daily for a 12 day trip in Northern Norway- (no washing during the trip) and they were perfect. Warm, comfortable, although definitely stiffer than the lightweight version. The only constriction was around my knees if I squatted down, but it was not uncomfortable and I didn't notice the fabric stretching out afterwards. The weave is tight enough that they are wind resistant. I am 5'4" and ~128 and I got the size small, no complaints. I don't tolerate pants that are too snug around my waist and so I really appreciate the wide waist band that wasn't too tight. Almost too warm to wear inside if the heat is on- I traded out for the light-weight leggings when I got too hot. Super pleased with this company and their products.

I will say that these were a bit scratchy/itchy when I first got them- but that diminished a lot after hand washing. I did notice that some of the dye came out into the wash water but less with each wash.

Hi Jessica! Thank you so much for sharing your experience! We’re thrilled to hear that you love the leggings and t-shirt, and it sounds like they served you well on your trip to Northern Norway!

It’s great to know that the wide waistband was comfortable and that the fit was just right for you. We appreciate your feedback about the initial scratchiness; hand washing often helps with that, and we’re glad to hear it improved with each wash.

Thank you for being a valued customer, and we’re here if you have any more thoughts or questions! Enjoy your day!

Love, love, love these!

I love, love, love these! And plan to buy more. They're more snug than what I'm used to but they loosened up, just a little (but I wouldn't call it saggy), around my knees and hips where I bend, which I need in order to feel comfortable. The rest of them have stayed snug and it turns out I like that because it keeps me warmer. I've worn them for 5 days without washing and they are still snug and warm. I'm about 5' 6", 125 pounds and bought a small. They're just right. I'm definitely buying more as my budget allows. Thank you Arms of Andes for a great product!

Great quality

I'm very impressed with the quality of the garment construction and I really like these heavier weight warm leggings. They do stretch when I bend down and the fabric does not spring back resulting with 'rings' of bunched fabric around the knees - but not a deal breaker.
