The Nomaflex REJ-050-4000-5 1/2 in. x 4 in. x 5 ft. Expansion Joint Filler (50 ft. Bundle) is a semi-rigid, closed-cell polypropylene foam that simply performs better and installs faster. Nomaflex is a closed-cell polypropylene foam that can be used in residential, commercial, civil, municipal and industrial applications. It will not absorb water, swell and disintegrate and it extends the service life of concrete by reducing the amount of imcompressible materials entering the joint. Nomaflex does not impede sealant cure time and can be used without a bond breaker with no impact on the long term performance of the sealant. Nomaflex resists oils, gas, salts, acetone and other chemicals. It does not leach like other products and is not sticky. Nomaflex is waterproof and can be stored outside. It will not break or flake due to weather elements. Nomaflex lasts longer and is 100% recyclable. Nomaflex fully complies with ASTM standard specification D 8139, and ASTM standard specification D 1751 for extrusion, compression recovery and water absorption as tested per ASTM test method D 545.

No flaws, not high end
Color: Pink, Size: Medium
I nabbed this for my in shape 14 year old son who had an upcoming wrestling banquet. It fit very true to size for him however as a low-mid grade dress shirt it had little flex or mobility across the chest and that’s ok, this is an entry level dress shirt and perfect for this and similar events. The color was vibrant and well saturated, and the fabric itself was thin enough for some transparency but thick enough to be considered medium weight. It would not be a cooling dress shirt. It did not have a soft hand, rather a sturdy rougher feel akin to a dress shirt a restaurant server would wear and laundry frequently which is also ok because it is exactly what a polo in this range should be. If you are looking for a flexible chest and soft touch you will need a better fabric blend and you pay a lot more for that. The buttons were nice and collar looked good. I would recommend this for any average event or occasion or even for work. If you are looking to impress on an interview or a date or during high heat you might need to look elsewhere. For what it is it’s perfect. Buyer and shirt need to remember this and keep it in its shirt lane.

Good shirt, not great, but it was never trying to be
Color: Navy Blue, Size: Medium
Let’s start with the fabric. The 50/50 cotton-polyester blend sounds like a compromise, and I suppose it is — but it’s a good one. You get enough cotton to feel like an actual shirt and enough polyester to keep things from turning into a sweat tent in the heat. It holds its shape after washing. No complaints. The collar is a genuine highlight. The pin tips keep the points flat and symmetrical, which is a small thing until you’ve owned a shirt where the collar curls after two washes. You’ll notice it. There’s also a hidden plaid print under the collar — a subtle detail that’s only visible when unbuttoned. Unnecessary, but charming. Fit is true to size. Order what you normally order. It’s versatile enough to tuck in for the office or wear loose on the weekend. Not going to replace your best Oxford. But at this price, it was never trying to.
