Aggregate customer ratings lean positive, with most ratings in the five-star category, but a notable share are one-star and the rating breakdown does not explain the reasons. This offers limited reassurance rather than a clear picture of fit, durability or FR performance. Those details matter for a non-stretch work shirt whose protection claims and pocket description should be checked against the garment and job requirements.
