Frontier GRN Line Backcountry Filter Cartridge - White & Green
9 sold in last 24 hours
The backcountry water filter cartridge is where quiet confidence lives: you click it into your Frontier Max and suddenly every stream looks different. Bright green caps and a clean white cage signal fast, safe flow while Miraguard technology goes to work against bacteria and cysts. Lightweight, chemical free, and made in the USA, it turns guesswork into a simple twist-and-sip ritual. Your pack stays light, your water tastes clean, and those miles ahead feel a lot less uncertain.
