The classic poncho is made of 210T polyester plaid fabric which is completely waterproof and tear resistant. It is equipped with an adjustable rain cap (which can be adapted to the helmet) with a deployment size of about 210X140cm. It can be put into the attached 21X5cm storage bag. The weight is about 300g. As a poncho, it can protect the whole body and the backpack to keep dry in rainy and snowy weather. It can also be fixed with rivets and metal rings to form a waterproof canopy, moisture-proof mat, tent, or used with a tramp's cloak. Multiple ponchos can be spliced together by rivets to form a large canopy
