At Forest Fundamentals, we’ve long relied upon the classic MK1 and MK2 canteen cups. For years, we made do with improvised tin-foil lids, never finding a proper metal lid that actually fit. So, we decided to design our own! The Materials: The lids are stamped from 304 Stainless Steel — highly resistant to heat and corrosion. Unlike aluminium or copper, it also doesn’t leach chemicals or react with food. Manufacturing: After stamping, we laser-engrave the logos to ensure they won’t fade with repeated use. The lids are then deburred and brushed to remove sharp edges and create a clean, textured finish. Benefits of the Lids: The advantages of lids are pretty clear! Lids help conserve all types of fuel and significantly cut down boil times. Spending ages waiting for your coffee to boil in the morning, or your meal to heat up after a long day’s hike, is never ideal. The Folding D-Ring Handle: The handle makes it easy to lift the lid when hot. We’ve increased the size of the handles for better grip when wearing gloves. The opening is also wide enough to use a stick or the end of a knife to safely lift the lid and check-on the cup’s contents. **Size Information** The lids are designed to specifically be compatible with the BCB Crusader MK1 and MK2 canteen cups only. They are not compatible with any other models. Disclaimer: This product is designed, developed, and manufactured by Forest Fundamentals.
