I would like to see a Ritter emergency shelter. Something that would get you out of the wind and rain quickly. One-handed would be even better.

I would also like to see a Ritter water filter and purifier system.

In the rule of threes; after oxygen to the brain, shelter/fire and water are next.

I think the Sparklite and TinderQuik take care of fire.
