When Crispi's expert staff thought up the Crispi Briksdal MTN GTX , they built possibly the world's best boot for the high mountain hunter. In other words - Maraviglioso!! It's a marriage of brushed microfiber synthetic combined with high-performance and rugged PUtek® fabric to provide structure, breathability, and abrasion resistance.
