Cotton is usually a little harder on the hands to work with due to it's inelasiticity but Pima 100 is a joy to knit with! Maybe it's due to the smoothness of the yarn. Pima 100 glides so easily off the needles without being too slippery and wasn't at all splitty.
The swatch was knit using size US 7 bamboo needles. The fabric was a little loose so if you like more structure, going down a needle size may help. The fabric is soft and light with great stitch definition and feels so nice next to skin. Pima 100 is a great yarn to work with in warmer weather.
