Review on ☕ Lethot Collapsible Coffee Cup: Portable 15.8oz Travel Mug for Camping & Hiking - Durable & Reusable, BPA Free Silicone - Grey by Corey Holloway

This Lethot collapsible mug is made of silicone with a hard plastic screw top lid. The lid has a silicone plug around the drinking hole that fits securely so I would trust it to hold liquids securely. The kit also includes a silicone straw, a plastic ring that can be used if you want to pour hot liquids into it and protect your hands, and a carabiner clip that you can attach to your bag. It folds into something about the size of plastic. Lid so it's easy to carry in your pocket. I especially like these cups for picnics where you can use this cup instead of disposable plastic cups and when traveling you can either pour a glass of water or share a large drink. There are many similar jars at Revain, and they're likely to be the same design, but you definitely want to make sure you have a screw-on lid so it doesn't leak if you plan to carry it with liquid in it. I give this 5/5 stars.
