Getting fit and healthy challenge – week 1
November 16, 2018I found these in Decathlon – basically an insulating layer to protect the tube from the drinking bladder against frost – I hope this works.
Positives: It has a zipper over the full length of the tube.
Negatives: I expected the insulation to be a bit thicker.
