Men's Force Relaxed Fit Short-Sleeve Pocket T-Shirt vs Men's Tech Training Short Sleeve T-Shirt: which is safer?

Where these two actually differ

• We flag Azo dyes and Microfiber shedding on the Carhartt and not on the Reebok.
• We flag Azo dyes and residual dye chemicals, Formaldehyde resins in finish treatments, Microplastic shedding during washing and Heavy metals in pigments (if dark dyes used) on the Reebok and not on the Carhartt.
• The Carhartt is 100% cotton jersey knit, untreated where the Reebok is polyester/cotton blend, standard knit, which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
