The satin finish to the outside is good to grip with gloved/wet hands and the wrist strap is useful to steady the bottle when filling.
The catch and lock to open/close the lid can be operated one-handed and, once shut, the bottle doesn’t leak even when inverted (can happen when in a rucsac). The drinking “nozzle” is good to drink from direct or use for pouring.
Made of material that is BPA free for those that are health conscious.
I would normally use a larger water bottle (750ml or 1 L) but two x 500ml are easier to stow in a rucsac.
Overall a good bit of kit that I will use for day walks or when backpacking on longer trips.
