This is thermo insulation built directly into the Thermo Bottle Belt - helping keep hot drinks warmer for longer.
The roll top opening on selected bags and packs allows for adjusting the volume depending on what you need each day.
Bottle belts like the Atomic Thermo Bottle Belt are a really efficient way to take your essentials with you without feeling weighed down. The padded belt’s got a front pocket for your phone and a removable thermo insulation pouch with rolltop for the Push & Pull drinking bottle (which is also removable – and dishwasher resistant). This season the hip belt has been fine-tuned to make it even more comfy as you’re skiing. And there’s a dedicated little pocket on the side of the hip for your car key. So you can stow it in there and leave it zipped up tight til the end of the day – no more car key panics!
