A Sleek, Resilient Shield for Modern Rooflines

This streamlined underlayment creates a refined, uniform foundation that elevates the roofing silhouette before the first shingle is set. I adore the high-traction surface—its quiet confidence underfoot speaks to thoughtful engineering. Pair it with charcoal architectural shingles and matte black accents to craft a cohesive, contemporary profile. It’s the discreet luxury layer every polished exterior deserves.

Too damn small
Color: Black
Way too small for an adult. It doesn't even fit my 11 year old. Unfortunately I didn't open it immediately or I would have returned it. Now I'm stuck with something nobody in my house can use.

One size definitely doesn’t fit. Otherwise Ok.
Color: Black
OSFM - one size fits most. It should be OSFS - one size fits small/some. Measured my head size and according to their chart I’m l/XL. This cap is tight fitting and gives you a headache after an hour. Otherwise it’s fine. Keeps your head cool, is absorbent and works well under a helmet.

Feels refreshing on the head…
Color: Black
I purchased a few of these on UA application. However, when I decided to put some more the UA app was out of stock. I love the skull caps!! I use them for the gym and for work. They’re very comfortable and outstanding if you’re in a hot environment, sweat a lot or just want to be cooler. They haven’t slipped at all and it’s great value for what I spent! So far I have seven in total. I may purchase three more shortly before summer hits that way I can use one at the gym and one at work per day and don’t have to worry about doing my laundry just to have clean skull caps.

The perfect sock!
Size: 6-10, Color: Halo Gray/Assorted
The only socks that I can wear with my hey dudes. They stay on my ankles and never slid down into the shoe. I will forever order these as long as they are available. They are comfy too!

Good option, especially in warmer weather
Size: 6-10, Color: Black
High quality socks and very durable. Nice touch adding the grip on the back of the ankle so the sock stays up. Size is a true fit to the size of your foot as well.
