Tetra UV ClarifiersThe reflective insert increases UV exposure and prevents internal UV degradation of the plastic housing. How does UV work? Pond water containing single cell algae is pumped into the clarifier. Ultra violet light destroys single cell algae's ability to reproduce. Single cell algae dies, clumps together and is removed by filtration. 15' Cord Length Removes heavy algae blooms usually within 10 days and keeps water green free. Product Info Item PDF Max

They are soft and well-made, but they are definitely NOT SEAMLESS, which was my whole point in buying them. There are two cross-seams, as well as a fairly thick hem seam on the legs. If you have a problem with inner thigh or genital chafing, you may want to look at a different brand. Otherwise, these are comfortable and well made. FYI, the ones I received had a matching inner liner, not a white one as some reviewers have noted.

Buying another package

Size: Large, Color: Multicoloured D (5-pack)

Oh my gosh, I love these!!! They are very comfortable and not overly tight. The material is so thin and breathable, very comfortable. Love the colors. Am buying another package! I'm in perimenopause and these definitely keep me cooler than my tradition cotton underwear.
