The only ice brick purpose-built for RE;Treat. RE;Chill was designed for people who can't afford a soggy lunch bag or a handful of melted gel packs by the end of a twelve to fourteen hour shift. Not a generic camping ice pack. Not a repurposed lunchbox brick. Built to match the exact shape of the RE;Treat 18L. Rigid HDPE shell, ultrasonic welded. -10°C Phase Change Material inside, sealed for life. No leaks, no punctures, no mess in the bottom of your bag. 280 x 180 x 23mm. Sits flat across the base of your RE;Treat 18L, holding cold underneath your food without eating into your usable space. Australian veteran-owned. Every RE;Chill sold works toward the RE;Shift Bush Retreat — a free, no-pressure property in the bush for first responders mental health to rest and reset.
