Core Nutritionals HydrateHydration is one of the most important factors in athletic performance. Yet, many of the mass marketed sports drinks widely available today fail to properly address the issues posed by sustained periods of intense exercise. A broad base of research demonstrates that proper hydration and electrolyte levels can delay fatigue, increase endurance, reduce delayed onset muscle soreness, and increase a wide range of athletic performance metrics.

Extremely thin material.
Size: 34W x 32L, Color: Midnight Selvedge
Really thin material. For the price I was expecting something closer to a buck mason quality fabric but these jeans are extremely light weight and I don’t expect them to last.

Denim feels thin but soft
Size: 32W x 32L, Color: All My Days Selvedge
The denim seems thinner than from years ago. 100% cotton feels soft. Fit me same as other stretchy 505 that are made with elastine. Waist size is fine. Haven't washed them yet. Yes, the price is high, but I like the 100% cotton and will likely buy more selvedge jeans.

100 cotton
Size: 33W x 32L, Color: Midnight Selvedge
These are great, just keep in mind that 100% cotton is not the same as 99 cotton 1 elastane, so size up if you tend to be in between mesures at waist.
