Here is a list of Amazon items that I take with me to every race:
DJI Osmo Action 5 Pro – The camera I use. This is by far the best action camera for dirt biking in my opinion. Record the entire race in 4k with no concern about battery life or overheating. Get the adventure combo, it’s worth it. amzn.to/4lyCics

SanDisk Extreme 256gb memory card - amzn.to/4bjE5yH

Aluminum tripod mounts for action cameras – These are great for attaching a camera to a chest protector. amzn.to/4bOiajn

Aluminum action camera extensions - amzn.to/4bzAaN9

Kijaro Camp Chairs – The best camp chair you’ll ever sit in. These are not the typical camp chair. Find me at a race and try mine if you don’t believe me. amzn.to/4rGyAiy

Armor Vision Smart Film for your goggles – The best recent innovation in dirt bike riding in my opinion. Keep your goggles on no matter the conditions and protect your eyesight.
62mm - amzn.to/4uxxnwx
50mm - amzn.to/47TXWCl
36mm - amzn.to/4uW1azt

McKesson Spot Bandaids – You know what these are for. These stay on regardless of sweat, etc. amzn.to/4uyTkvr

Elastikon Medical Tape – This tape sticks better than any other. Don’t buy the cheaper copies. Put it anywhere you typically get blisters. I use it on my clutch finger and to cover a scar on my palm. amzn.to/4cXjPnW

Lasko Blower Fan – This fan concentrates the air in one direction so you can aim it right at your chair during/after races in the summer months. amzn.to/4skyez5

Tire spoon set - amzn.to/4uEMnss
