Rash guards not always best when expensive; drying speed and elasticity vary greatly

A recent evaluation by the Korea Consumer Agency has revealed notable differences in the performance of women's rash guards, despite all nine tested brands meeting the UPF 50+ standard for sun protection. The agency assessed functionality and safety aspects, including drying speed, elasticity, and durability, across brands like Discovery Expedition, Renoma, Lazybee, Roxy, and others.

Drying speed, crucial for preventing hypothermia and maintaining comfort during water activities, varied among products. Lazybee's "Essential Loose Fit Women's Zip-up" excelled in drying speed for tops, while Renoma's "Women's Solid Wrap Water Leggings" and Roxy's "Together Surfing 3" performed best for bottoms. In terms of elasticity, measured by recovery rate after stretching, Lazybee tops and Roxy and Barrel bottoms received high marks.

Durability tests for tear strength and seam strength also showed distinctions, with Roxy, Musinsa Standard Sports, and Anda'r products performing well in both categories. While most products met quality standards for zippers, pilling resistance, and snagging, one product, a pair of shorts from Xexymix, showed lower colorfastness when wet, potentially leading to color changes during wear. Several brands, including Lazybee, Roxy, and Arena, were noted for issues with labeling accuracy, such as incorrect KC mark placement or inconsistent washing instructions.

Price points for rash guards showed a significant disparity, with tops varying by up to 2.5 times and bottoms by 1.8 times. Musinsa products were the most affordable at 49,900 won for both tops and bottoms, while Roxy and Barrel offered the most expensive options, with tops reaching 125,000 won and bottoms 89,000 won. The agency advises consumers to check essential features like sun protection and drying speed, alongside design and durability, before making a purchase.
