Mount this Quick Cage by TwoFish Unlimited to a bike frame, stroller or pretty much anything with a similar diameter and you'll have a handy holder for a 40 ounce water bottle. This carrier, in large, from Klean Kanteen was originally designed to affix your bottle to a bike frame, but you can attach it to almost anything using the adjustable touch fasteners. The vinyl-coated stainless steel construction provides a quiet, secure fit that protects brushed and painted finishes.
