Thanks to everyone for the advice in this conversation. I'm just back from Namibia and was 100% squared away thanks to the input. From camp shoes to deal with the cold in the morning in the tent to a broad-brimmed hat to deal with powerful sun, I was packed just right. I used everything, and wanted for nothing except for saline eye wash. The grit in the air in Namibia was incredible. I had eye drops (used them most days and the guys I was with, all natives, had their own with them at all times), but I needed to irrigate my eyes after shooting a kudu. I was told that some people are allergic to kudus and that they have incredible allergic reactions after touching kudu. My eyes burned like they were on fire after the kudu hunt. They were red slits. We irrigated them back at camp with an expired saline solution, powerful antihistamines (bring more than you expect), and I had to stand in the shower to clean my eyes even more. On the next day out, my eye mask for the airplane was used as an eye patch. I protected my shooting eye and removed the patch when it came time to shoot. After a day of recovery, the eye problem went away, but I became very proactive in keeping my eyes irrigated and taking strong antihistamines. If the wind blows in from the east, you get a desert wind, and it is hot and extra gritty. A lot of locals carry eye drops and antihistamines for that very reason. Even the car engines are surrounded by filters to keep them clean Hopefully, this helps some others.
