Quick answer
Choose the Polar Sport 20oz/600ml Pulse if you want the lightest, most compact bottle for running and gym sessions. Choose the 24oz/700ml Splash if you need more drink for longer practices or game days and don't mind a slightly larger bottle in hand.
The 100ml gap matters more in hand than on paper
Both bottles share the same slim, ergonomic shape, ultrathin exterior, Sport Cap and integrated Dash Handle. The real difference is capacity: 600ml versus 700ml. That extra 100ml is roughly a few extra swallows, which helps on longer outings but adds bulk to the bottle you're gripping.
If you mostly run or lift, the smaller Pulse is easier to hold and carry without noticing it. If you're on a practice field or sideline for an hour or more, the Splash's extra volume can mean fewer refill trips.
Price and color: the practical tie-breakers
The Pulse lists at USD 9.30 against a USD 15.00 comparison price, while the Splash lists at USD 11.04 against USD 16.00. The Splash costs a little more for its extra capacity, but both sit in a similar budget range.
Both models offer color options, so if you're matching team colors or gear, neither size limits you. The choice comes down to how much you drink between refills and how much bottle you want in your hand.
What the shared design means for your decision
Because the Sport Cap, Dash Handle and squeeze-friendly body are the same across both sizes, you're not sacrificing flow or grip by picking one. The cap pushes closed for a tight seal on both, so neither is more leak-resistant by design.
That means you can decide purely on volume and hand fit rather than features. If you're torn, start with the size that matches your longest regular session, not your shortest.
Key trade-offs to weigh
- Capacity vs hand feel: The Splash holds 100ml more, which means fewer refills on long days but a slightly larger bottle to grip. The Pulse is smaller and lighter in hand for quick sessions. Pick the size that matches your longest typical workout, not your shortest.
- Price vs volume: The Pulse is listed at USD 9.30 (comparison USD 15.00) and the Splash at USD 11.04 (comparison USD 16.00). You pay a little more for the extra 100ml. If budget is tight and your sessions are short, the Pulse covers it.
- Shared features vs size-only decision: Both bottles use the same Sport Cap, Dash Handle and squeeze body, so cap flow and grip are not differentiators. Decide on capacity and hand fit alone. Don't expect one size to seal or flow better than the other.
