They run true to size. Fit was very comfortable. But snag easily and no pockets. But stayed warm

Base layer only - no pockets

Not as warm as I would like - and truly just a base layer only - no pockets - so cannot double duty as an outer layer - tights only

dont be deceived by their appearance

I was worried when I got these that they would be a) to small b) not thick enough. However, I've been on 3 runs with these in about 36-degree F weather and they are super! light weight, compression, and wicking. my legs never got cold.

AMAZING ColdGear® Women's Leggings
Originally posted on Under Armour

I live in the Northeast and Fall and Winter can be brutal. This year I wanted to be prepared so I purchased the ColdGear® Women's Leggings! Buttery soft and warn but not too warm or too think. So comfy! The only suggestion is to add a side pocket. Not too big of a deal for me because this time of year I usually wear some type of jacket or coat with pockets. Still it would be nice to have a pocket. Don’t hesitate! These pants don’t disappoint

These pants are great, they don’t slip when I’m working out. Usually I have the issue of having to pull up my pants after certain movement but not with these

The “tall” leggings aren’t very tall
Originally posted on Under Armour
Yes, I recommend this
I am just under 5’10” and ordered the tall leggings. I was pretty disappointed to see that they are not actually very tall at all. I have a pair of regular size length leggings, too, and there is hardly a noticeable difference. Also, they really need to start making these with pockets. It’s 2025; pockets are essential.

Awful Quality of Manufacturing
Originally posted on UnderArmour.co.uk
No, I don't recommend this
I have only just gone to wear these for the first time as I am trying to get back into running. The entire seam around the inside of the waistband has completely unraveled. I have owned Under Armour leggings over the years and they have been brilliant. This pair seems very poorly made, making me second guess the quality of Under Armour leggings.

Hi, Ibanez! Oh, no! Looks like our leggings weren't as durable or long-lasting as you, and we, expect! We sincerely apologize and appreciate you for calling this out. We'd love a chance to make this right and I'll email you soon to get more details. Talk to you soon!
comfy, warm, quality made.

I'm a tennis player & wear these leggings under a tennis skirt. In winter my outdoor tennis playing requires long leggings & long sleeves. The ColdGear Leggings material has a nice thickness, feels durable, has compression & is soft to the touch inside & out. The waistband is well designed. I like my athletic waistbands around my hip bones; therefore, I adjust all my legging waistbands to personal comfort. I'm 5'6"_112lbs. I wear UA x-small to be as fitted as possible. I ordered Tall because I like to cover my ankles. This length is about 3/4" too long on me, but not a bother since they're leggings. I like these leggings very much for: Tennis - the compression feels great around my knees & hamstrings. Light Activity - softness, warmth & durability. Lounging - softness & the compression is helpful for circulation.

Not the most flattering colour or material
Originally posted on UnderArmour.co.uk
The fabric felt soft and the fit was great (not too tight, not loose either), but this grey/or the material was not the most flattering as I could see my cellulite around my glutes.

2025// Still pocketless.

How is it that in 2025, these don't have pockets? The majority of users have a phone, wallet, and keys. Ridiculous
