In the Marine Corps I used to run 8 miles a few days a week in direct sunlight in southern california. It wasn't even particularly humid, and I'd still get perilously close to heat exhaustion. Then I realized I could put a large icepack under my close-fitting camelback. Instant portable AC. This hack alone made a shocking difference in my performance.
- sbate1987 5y agothanks this is a great idea - I discovered this last summer... This really does work - I had to keep an icepack in my bag to keep my emergency protein bar from melting on my all day bike rides and I realized how much cooler I was from just that tiny bit - but then I have the condensation issue.
- LorenPechtel 5y agoInteresting idea! Hiking I fill my hydration bladder with ice cubes then add water and I slip the whole thing in an insulated bag, but I never thought of using an actual ice brick for cooling. (And in most situations I don't think I would, anyway--too much extra weight. The ice in my pack becomes drinking water later.)
