Narrow Mouth Loop Cap

sku# 33205360600000

Product Description


Narrow Mouth Loop Caps are now vented. This allows hot vapors to escape before and during closing the lid so as to allow them to close smoothly and cleanly.

Perfect for everyday use, as well as the rigors of the outdoors, our Loop Caps provide a leak proof seal which aides in keeping your Hydro Flask contents cold or hot. Clip to a backpack or messenger bag and take your bottle on the road.

Our Loop Caps are Patent Pending and made from polypropylene (PP#5), which means they are BPA-Free!
