Siply is a line of leak-proof drinkware from Zak! Designs. It comes in three silhouettes — Straw, Clutch, and Grip — and each silhouette is available in two materials: vacuum-insulated stainless steel for temperature retention, or lightweight plastic for everyday carry. Every Siply bottle is leak-proof when the lid is open and when it's closed, fits a standard cupholder, is easy to clean, and is top-rack dishwasher safe.
If you've ever thrown a bottle in your bag with the straw up and prayed, Siply is the bottle that stops the prayer.
Straw for the always-sipping
Take a sip, throw it in your bag with the straw still up. Nothing leaks. The Straw is for people who don't want to think about their bottle — just drink from it. Desk, gym, commute, repeat.
Best for: All-day sipping, hands-free workflows, anyone who hates twist-and-flip rituals.
Clutch for the on-the-move
Small enough to fit where most bottles can't: laptop sleeves, gym bag side pockets, glove boxes, the cupholder of a stroller. Open it on a moving treadmill, close it without looking — neither state leaks.
Best for: Travel, commutes, bag-stuffers, anyone who wants drinkware that disappears.
Grip for the all-day
Bigger capacity, full handle, still fits a standard car cupholder. The Grip carries hours of liquid through long workdays, road trips, hikes, and job sites. Open it on a bumpy fire road, close it one-handed — still sealed.
Best for: Long carries, big-volume drinkers, anyone who refills once a day instead of four times.
Same silhouettes. Same leak-proof engineering. Different jobs.
Vacuum-Insulated Stainless
Double-wall stainless steel construction keeps cold drinks cold and hot drinks hot for hours. Heavier in the hand, premium feel, dent-resistant. The right pick when temperature retention matters — long workdays, hot coffee on the road, ice water in the car all afternoon.
Plastic
Lighter, more affordable, expanded color and pattern range. Built with the same leak-proof seal as the stainless line, but without the temperature retention. The right pick for kids, sports, outdoor activities, or anyone who wants Siply's leak protection without the weight or the price.
Most bottles leak the second you flip the lid up or click the straw out. That's the moment your bag, your laptop, your leather seat, or your kid's car seat takes the hit.
Siply seals both states. Lid open or lid closed, tilt it, drop it sideways into a tote, kick it under a passenger seat — the liquid stays inside. You don't have to think about it. That's the whole point. And it's true of every Siply, stainless or plastic.

Same silhouettes. Same leak-proof engineering. Different jobs.
Keeps drinks cold or hot for hours. Heavier, premium, dent-resistant.
Lighter, more colorful, more affordable. Same leak-proof seal — no temperature retention.
Leak-proof when open. Tip it, shake it, throw it sideways in your bag. Straw always up, lid flipped, spout exposed — doesn't matter. Nothing leaks. This is the feature that defines Siply.
Leak-proof when closed. Sealed against the worst-case bag dump, backpack toss, or stroller jolt.
Cupholder friendly. Every base — even the Grip with its handle — fits a standard car cupholder.
Easy to clean. Wide-mouth or removable lid components for fast hand washing.
Top-rack dishwasher safe. Pop it on the top rack, take it out, refill.
BPA-free. Across both materials.
Siply is a line of leak-proof drinkware made by Zak! Designs. It comes in three silhouettes — Straw, Clutch, and Grip — and two materials: vacuum-insulated stainless steel and lightweight plastic. Every Siply stays sealed whether the lid is open or closed.
All three Siply silhouettes share the same core engineering: leak-proof when open and closed, cupholder friendly, top-rack dishwasher safe. They differ in form. Straw drinks through a straw and suits all-day sipping. Clutch is the most compact and portable. Grip has a handle and a larger capacity for long carries. Each silhouette is available in both vacuum-insulated stainless and plastic.
The stainless versions are double-wall vacuum insulated — they keep drinks cold or hot for hours. The plastic versions are lighter and more affordable, with a wider range of colors and patterns, but they don't insulate. Both materials share the same leak-proof engineering, cupholder-friendly base, and top-rack dishwasher safe construction.
No. Only the stainless steel Siply bottles are vacuum insulated. The plastic versions are single-wall and not designed for temperature retention. They are still leak-proof, cupholder friendly, and dishwasher safe.
Yes. Every Siply silhouette in every material is leak-proof in both states — lid open and lid closed. Most bottles only seal when fully closed; Siply seals when the straw or spout is open too.
Yes. Both the stainless steel and plastic Siply bottles are BPA-free.
Yes. Every Siply bottle — stainless or plastic — is top-rack dishwasher safe.
Yes. All three Siply silhouettes, in both materials, are sized to fit a standard car cupholder, including the Grip with its handle.
The seal is engineered into the drinking mechanism itself, not just the outer lid. The Straw silhouette uses a fixed, always-up silicone straw with an integrated leak-proof design — the bottle stays sealed in any orientation, tilted, sideways, or upside-down in a bag. The Clutch uses a leak-proof spout that holds the seal whether open or closed. The Grip uses a folding spout that lies flat to seal and lifts up to drink — leak-proof in both positions.
The Siply Straw silhouette uses a soft silicone straw. It's gentle on teeth, easy to clean, and built for daily use.
