As crackpacs are made from canvas tents and other sensitive material they have some special care requirements.
1. DO NOT WASH
Clean off dirt with a brush, when dry, and if necessary a damp cloth.
crackpacs are waterproof treated after being made, to ensure maximum water repellency, as is the nature of canvas they may require re-waterproofing. We recommend using a tent protector treatment available in most outdoor retailers.
2. If your crackpacs get wet, as with canvas tents, ensure it is hung until fully dry before putting away.
