Check out this list of Top 10 Backpacks for the SEALFIT 20X Challenge Event.

We get this question alot; “Coach, what backpack do you recommend for training and to do a SEALFIT 20X Challenge?

That is a great question, so we checked in with athletes that have finished the event.

This is the same backpack that is issued at SEALFIT Kokoro. It is not very comfortable. The straps break occasionally.

If the strap breaks you just have to deal with it. The backpack is not meant to be comfortable it is meant to be part of your obstacle.

Yes. That is all you need for Kokoro camp.

Mark Clingen used this same backpack to complete a recent 20X Challenge in Canada. You can read an interview here.

The ALICE pack has been a staple for rucking and moving equipment in the military. Many athletes have used this type of pack to complete long endurance events like GORUCK. Craig Graves used a simple ALICE Pack for his SEALFIT 20X Challenge.

You cant go wrong with this pack as it is a great price under $75 and you can reuse it to haul your gear to the gym.

JN Gross: I used an Explorer B5-BK backpack. The straps were comfortable but in hindsight I wish it had a waist strap. I actually intentionally didn’t get a waist strap bag because I didn’t think it would be allowed but I would definitely have it for next time.

It moved around a lot on my back during pushups and planks, making them more difficult than they should have been and later one of the shoulder straps actually ripped off and I had to tie the strap off on one of the molle points. It got through the day but it’s now been retired into a sandbag in my garage.

What body lubricant do you recommend for an endurance event like SEALFIT 20X Challenge or GORUCK?

I recommend either Bodyglide or Trail Toes as a body lubricant to keep my toes and crotch from blistering.

A little bit of lube can go a long way to helping you finish the course without getting chafed. You dont want to get half way through an event and your butt is all chafed.

Take a little bit of extra precaution and get some lube for your private parts.
