My son lives in these pants! He plays soccer, basketball, and runs track, and these Under Armour Unstoppable Tapered Pants are his go- to for everything. Pros: Durable: They 've held up incredibly well to all the wear and tear. No rips or tears even after months of intense use. Comfortable: The material is soft and stretchy, allowing for full range of motion. They do n't feel restrictive at all, which is crucial for active kids. Moisture- Wicking: He stays dry and comfortable even during the most intense workouts. Stylish: They look great too! He loves the sleek, tapered fit and the variety of colors available. Cons: Price: A bit pricier than some other athletic pants, but definitely worth the investment in my opinion.

Great overall sports bra that does a great job of supporting, but not constructing or being too crazy supportive.

5 I fall off rocks
So I 'm one of those weirdos that only wears sports bras, and have for my entire life. I hate traditional bras and I love compression-- like, the flatter the better. I do n't want to feel any movement in my chest area. I 've also been `` blessed '' with boobs that just want to flop and have a tendency to stretch out all of my sports bras. For reference, I 'm 5' 5 '', ~138 lbs and I 'm around a 32 D. Medium is perfect for me. The only caveat is that most of my activity leans toward medium impact-- I 'm a climber, so I take lots of hard bouldering falls and spend long days in the mountains, but I do n't do much sustained high impact activity like running or crossfit, so if either of those are your jam, take my recommendation with a grain of salt.:) Anyway, I 'm 6 months into wearing this bra daily, and I love it so much. I was a little leery of the adjustment buckles on the front before trying it on, but they 're actually very slim and low profile. I do n't notice them and I have n't had to adjust them yet, and they do n't stand out under my shirts. The amount of compression is just right-- snug but comfortable, like a hug. The mesh is breathable, wicks well, and so far has been impressively odor- resistant. Best of all, no flopping! It's the first sports bra I 've owned that I can wear all day, transitioning from activity to activity, and have n't felt like I 'm either being suffocated or drowning in my own sweat. I can spend a strenuous day hiking or climbing, sweat a bunch, and come back into civilisation without feeling like I need to change right away because it dries super quickly and amazingly(!), does n't stink or give me rashes. And I have n't even managed to stretch it out yet-- it still feels almost as snug and comfortable as when it was new. I 'm honestly impressed with the combination of performance, durability, and comfort. Most of my sports bras start out great but become borderline unusable after a few months and a couple of washes. Not this one. For me, personally, this is a winner-- I 'm a convert and it might be the only bra I buy from here on out.

5 Kat S
I have three of these sports bras and they are great for running as someone with a larger chest. Adjustable straps are a huge plus. For reference I am a 32D and wear a size small.

5 Amm76
This top fit great and performed well. No chaffing from a longer run.

5 Tammy A
This bra fits well as the size. I appreciate that there are 4 clasps that can be adjusted to fit around my chest. The straps can also be moved a lot to provide comfort. The bra sits comfortably on my shoulders. There is proper ventilation where needed. I highly recommend this bra.
