Mandatory

MARLOAR Soft Flask 500 ml (pack de 2)

Two-pack of 500 ml BPA-free silicone soft flasks for running, trail, cycling and hiking. Wide mouth for fast refills, they collapse as you drink, and the per-bottle price is a fraction of the branded ones, so you can rotate and replace them without a second thought.

Watch out for

−Silicone is heavier and tastes slightly more than branded TPU flasks
