HydraPak 42mm Speedfill Cap

$21.99

The HydraPak 42mm Speedfill Cap is a replacement cap with a flip-open, high-flow spout for compatible 42mm soft flasks from HydraPak, Salomon and Nathan. It suits racers and long-day runners who are tired of slow, splashy refills. Swap it on and topping up from a tap, jug or aid-station pitcher gets quicker, with a twist-on seal designed to stay leak-free in your pack or vest.

Wide, flip-open spout makes refills quick.
Easy to fill one-handed at an aid station.
Twist-on seal keeps things leak-free in a vest.
Rinses clean without fuss.
A cheap way to speed up a flask you already own.

Less suited to: Runners who want to filter water from streams. For that, look at HydraPak, including the 42mm Filter Cap.

Slow refills cost time and leave you wearing half the water. The Speedfill Cap is a small fix for that problem, and it works with the 42mm flasks runners already carry. It is a simple upgrade for race day.
