Nitecore NB10000 Gen 3 vs Polar Grit X: which should you buy?
If saving weight is your priority, the Polar Grit X wins — at 64 g it is 86 g (57%) lighter than the Nitecore NB10000 Gen 3 (150 g). That said, the heavier option may justify the extra grams with more capacity, durability or comfort, so weigh the trade-off against how you'll use it.
