Review on Amphipod 12 oz Hydraform Handheld Thermal Lite Insulated Runners Hydration Bottle Black: Stay Hydrated and Run Comfortably by Christopher Yap

The product is exactly as I imagined. Well designed and high quality. Fits my hand well. I have a bit of a problem with leakage if the lid isn't screwed on very tightly, which may be because the hole is large (about 1.5" in diameter). I'm thinking of simple plastic bottles that tighten very securely with very little pressure, so I'm wondering why this design leaks so easily unless I put a lot of pressure on it.
