Where these two actually differ
- We flag Azo dyes in synthetic fibers, Elastic degradation and leaching, Antimony in polyester fiber and Microplastics shedding on the Boyshort and not on the Ruby Love.
- We flag Coating degradation and microparticle shedding and Bacterial or fungal growth if improperly stored on the Ruby Love and not on the Boyshort.
- The Boyshort is Cotton blend, elastic waistband where the Ruby Love is organic cotton, waterproof backing layer, which is most of the difference in these two grades.
- The gap is 30 points, wide enough that this is not a close call, and the Ruby Love is the one to buy.
