Brush loft comparisons

The New Forest brushes are 2 band 22 mm knot size set at a loft of 55 mm and 50 mm. The Simpsons brush is 22 mm knot with a loft of 52 mm.

Note the similarity of the brush hair and the differences arising from variation in lofts. 2 mm and above make a big difference to the feel and performance of a brush.
