What each one gets wrong
Fenix HM65R-T
- Weight on the forehead matters; this is the heavy end of the category
- You want it to run at 1,500 lumens rather than step down to hold temperature
- Simple is the goal — two buttons and separate emitters take learning
Nalgene Wide Mouth 32 oz
- You want a cold drink to still be cold in four hours
- Condensation on the outside will be a problem
