"A review of summit day photographs will show that I was clothed in the latest, highest quality, high altitude gear, comparable, if not better, than that worn by the other members of our expedition"

In this quote, Anatoli Boukreev is specifying that upon reviewing photographs from their top day, it will appear that he was using the most advanced and premier gear for high altitude conditions. He goes on to say that his gear was on par, if not superior, to what the other members of their expedition were wearing. This suggests that Boukreev was well-prepared and equipped for the difficult conditions they dealt with during their climb. He is most likely utilizing this declaration to defend himself against any criticism or doubt about his equipment choices and to establish his reliability as an experienced and skilled mountaineer.
