Refund
Use the warranty for a pair of sunglasses that I bought and the lens broke on me and Asurion refunded me the total cost of the glasses.

Versatile and athletic top
Size: Medium, Color: Black Gray Blocks, Size: Medium, Color: Black Gray Blocks
This sleeveless shirt is so cute! I like the collared look and the cheetah print. The material is super lightweight and breathable, with solid moisture-wicking It dries fast too – huge plus.
The collared design gives it a polished look that works on the golf course or grabbing lunch after, and the stretch feels comfortable without being clingy. Sizing ran pretty true for me, and the UPF protection is a nice bonus for sunny days.
I think it’s versatile enough that the top can look nice with some slacks for an office vibe too. Great value if you’re looking for performance without spending a fortune.

Cute striped athletic tank
Size: Large, Color: Pink Purple Stripes
such a cute and comfortable athletic tank to wear for many activities!
The material is lightweight and breathable but is also so soft and makes wearing it super comfortable for any athletic activity or just for wearing casually on a hot summer’s day.
The fabric seems very high-quality and has some stretch to it. The tank top does fit true to size. The collar is a very cute detail and makes this tank top feel fun and flirty and feminine.
I love the pink stripes pattern. It looks cute tucked into a skirt or shorts. This is a cute tank top for Pickleball, tennis, golf, or simply just running errands.
This has washed well and I usually hang up to dry all of my athletic wardrobe. It does dry quickly and does not dry wrinkly even when just clipped up to dry.
I think it is a good value for the tank top that you get and definitely looks like it came from a sporty sports outlet and definitely doesn’t look or feel cheaply made. Very happy with this tank top and would definitely recommend!
