STANLEY IceFlow 20 oz Flip Straw Tumbler with Handle
The IceFlow Flip Straw is the tumbler you can actually throw in a bag. A twist-on lid locks a flip-up straw into place so it stays leak-resistant when it tips over in a daypack, and the double-wall vacuum insulation keeps ice solid through a long summer hike. The rotating carry handle folds flat and doubles as a hook for the outside of a pack, and the tapered base slides into most car cup holders. At 20 ounces it is big enough for a real water break and small enough to carry every day, and the stainless body is built in part from recycled plastics.

Standard tumblers leak the second they tip over in a bag, so you either carry water you cannot trust or drink warm water all day.
🏆 How It Compares
Versus a classic open-lid tumbler, the IceFlow adds a locking flip straw and a folded handle, and versus a 32 oz insulated bottle it is lighter and easier to sip from but holds noticeably less.
Pros & Cons
✅ Pros
- Twist-on lid with flip straw is genuinely leak-resistant, unlike open-lid travel tumblers
- Double-wall vacuum insulation still has ice after a full day in a hot car or on a trail
- Rotating handle folds flush and hooks onto a backpack strap or carabiner
- Tapered base fits standard cupholders, and the steel body is partly recycled material
❌ Cons
- Not fully leakproof if you invert it or leave the straw open under pressure
- Straw and lid need a bottle brush to clean properly, no dishwasher shortcut for the lid
- 20 ounces empties faster than a full 32 oz bottle, so you refill more often
