Bigger than anticipated with lots of extras thrown in. Extras include a sports strap, spout restrictor, and straw. The sports strap is very sturdy (very durable i am confident it won't slip off or rip) and easy to install. Will definitely make hiking or any long walks in general easier so you can just wear the bottle instead of holding it.. The spout restrictor will not hold on its own with out the straw and also will not allow for the cap on the bottle to close. If using the straw alone the cap will close but the straw has a modified end for endurance drinking as well if desired for use in combination with the restrictor. The handle bottle and all parts are sturdy and well built and it comes with a fluid level scale on the bottle in both ml and oz. And cap comes with a small push button latch and rubber leak stop plug in the cap. Highly recommend. Recycle numbers 5 and 7. Bottom says rated to handle temperatures 20/120 c - 20/100 c gasket is also inside inner rim of lid. Overall great buy!
