The shaker goes in the bag with the towel and the phone, upside down, and you find out on the metro whether the lid meant it.
What Are the Key Features of This Leakproof Plastic Shaker Bottle?
Plastic, so a drop is not a dent - a steel shaker that falls off a bench carries the mark for life; this one does not keep the evidence.
A flip lid over a silicone seal - the leakproof mechanism as described, and the reason a shaker can go in a bag mouth-down rather than standing up in a side pocket.
1 L for the gym, 750 ml for the desk - both sizes are sold, and the smaller is the one that fits a drawer and a school bag.
One of the colours is transparent - the only version that shows you whether the powder dissolved or is still a lump at the bottom.
Blue, green, grey, red or clear - five shades sold, which matters in a gym where four identical black shakers end up on the same bench.
Where Can You Use This Shaker Bottle?
In the gym bag, carried mouth-down between the towel and the phone
On a desk through a working day
In the car on the way to training
On a walk or a run
Any training session where a protein mix has to travel
Why Is Plastic Better Than Steel for a Protein Shaker Bottle?
A flip clip over a silicone ring - the seal as described, and a different job from a thread that only closes if you tighten it the same every time.
A mix and a drink - one full pre-workout mix still leaves water for between sets, so you skip the queue at the gym cooler.
Mixed at home, carried full - you fill it from your own tub instead of carrying loose powder to measure out at a bench.
Details
Material & Build
Plastic body - takes a drop on a hard floor without carrying the mark, and is the only material that can be sold in a see-through version.
Flip lid over a silicone seal - this is what it is sold as leakproof on.
Anti-bacterial additive: claimed as an additive in the plastic.
No thermal claim of any kind: this holds a cold shake and is not a flask - nothing says otherwise.
