IFR aviators at all levels will love these Flip-Up Training Glasses from Jeppesen. Designed with comfort and utility in mind, the Shades secure via an adjustable Velcro strap that fits comfortably under headsets and reduces pressure on the temples and ears. They also feature flip up lenses to quickly and easily simulate "breaking out" on an instrument approach. The Shades are both lightweight and compact for easy storage, and their high-quality polycarbonate construction ensure the lenses will hold for reliable use again and again. An affordable, incredibly well-designed item that IFR pilots and CFIIs will appreciate.
