Review on 🥤 Telescopic Silicone Travel Cup with Lid - Collapsible Water Mug, Reusable Drinking Tumbler for Picnics, Snacks, and Camping by Tom Lantz

I needed a collapsible silicone mug that I could fit into my Titan Travel Pot (both 650ml and 750ml sizes) in addition to other parts of my kitchen system . This product has a slightly small capacity but fits perfectly in a pot. The 3.54 inch diameter was just what I needed. I've tried using the mug to make coffee and tea, and after pouring boiling water into it, there's no smell or taste. I don't use a lid, so the mug alone adds 54 grams to my ultra-light setup and allows me to have a hot drink while I boil water for oatmeal.
