This set of polyurethane bottles is ideal for use with alcohol stoves. Depending on the length of your expedition, you can choose bottles of appropriate sizes to conserve space in your pack. The bottles feature a screw-on lid for simple refilling and a flip-top cap that facilitates easy pouring into alcohol stoves while preventing leaks. An excellent lightweight alternative to many heavy metal denatured alcohol containers. The efficiency of alcohol stoves varies greatly depending on your setup, with the wind having a significant impact on fuel consumption. Typically, one meal requires 30-45ml of fuel. For short hikes or day trips, we've included a 30ml bottle. For 2-day hikes, we usually consume 150-270ml of fuel for three meals a day plus coffee. Carrying two 100ml bottles helps you accurately manage fuel reserves for the next day. We always recommend carrying extra fuel to ensure you have enough. For 3-day hikes, 270-400ml of fuel is typically needed for three meals a day plus coffee. Testing your stove at home under different conditions is advisable to gauge your exact fuel needs. Includes: 1x 30ml (1.01 fl oz), 1x 100ml (3.38 fl oz), 1x 200ml (6.67 fl oz) bottles. DISCLAIMERS: Although these bottles are leak-proof, we always recommend carrying denatured alcohol in an additional zip-lock bag. Please note, these bottles do NOT come with fuel. STICKER ISSUES: During production, some stickers developed bubbles under the surface. While the functionality remains unaffected, we’ve adjusted the price accordingly to avoid unnecessary waste.
