I purchased this COLLAPSIBLE CUP with Lid by R&L US for my bug out emergency kit for when North Korea bombs us or russia lol. It is well made and heavy duty and collapsible so you can easily throw into backback or any bag for that matter. Lightweight folding cup great for outdoor camping, hiking and travel. BPA-free, hygienic, made of 100% food-grade eco-friendly silicone. Dishwasher safe.
