I done the Safari last year. I went through a few different idea's but after 7000km's between the pre-safari rides and the event itself, i ended up with the following (ground up)
FOX F3 boots - Due to their stiff design i can relax my ankles when I stand.
FOX thigh high sock - As i wear knee braces.
Astrix Knee Braces - They are super comphy over long days!
Nics - These are the padded shorts for riding bicycles.
Under boot MX style pants - These dont get caught up in tree's or the bike.
Thermal long sleeve shirt - Best anti-chaffing protection!
AXO pressure suit - This is the best armour i found to use with the Leatt!
Leatt Neck Brace - Just cause i like walking soooo much!
KTM Rallye jacket - Fits great and has so many useull pockets!
FOX gloves - Unsure of make but they have the carbon fibre knuckles.
MEDICAL TAPE - over the usual blister points.
MSR Rev3 Helmet - This helmet fits my head, but im looking at the Arai's now!
Scotts Desert Goggles - These goggles are the best ive used for keeping the sand out and they still dont fog up!
Anyway thats that i usually wear, for rally's! Everything is usually the same when i got for a small ride but i wear a jersey instead of the jacket! Camel back is a must, and go for something that can hold a fair bit of gear! And there are two rules i stick to
1- Always keep the weight off yourself. Put it on the bike any way possible!
2 - CHAP STICK!!! The KTM Rallye jacket has a cool little pocket just for it!
Safari 2011 ! ........anticipation!
