- CSCory S.Verified Buyer11 seconds agoRated 5 out of 5 starsGreat shirt
Fits well not flashy and made well.
- DBDustin B.Verified Buyer1 month agoRated 5 out of 5 starsTough stuff
Awesome shirts, no shrinking, no wrinkling, they hold pretty well and I get compliments and people asking where they can get them all the time. It's the only shirt I wear now, top quality stuff these folks are putting out!
- WWillVerified Buyer1 month agoRated 5 out of 5 starsGood quality shirt with a few improvements needed
Im 5 ft 11 and medium fits perfect. The fabric is made in usa but the shirt is stitched overseas. Collar is nice and buttons look quality Would hope in future for a 100 percent usa made shirt and also possibly triple stitch high wear areas?
UUpInSmokeWelding1 month agoHi Will, appreciate the feedback. We do offer many products that are fully made in the USA. Our Zestos platform is switching to triple stitch currently and will be on our website by the end of March 2026 in limited colours and more will be coming by the end of April 2026.
- JCJowan C.Verified Buyer9 months agoRated 5 out of 5 starsBoiler and pipe welder
These offer brilliant protection and flexibility in comparison to wearing boilersuits. In the UK we don't really have much in the way of work shirts, it's always been overalls however with the heat and humidity I was looking for something different and these have ticked every box. We've been using them inside boilers for inserts and tubes as well as outside for pipeline welding all with stick and they're brilliant. Will be buying more in the future.
