The bestseller Amigo Hero is a very popular rain sheet (0g fill) with a lighter outer material in 600D, but this sheet has Ripstop outer material which makes it stronger than the regular Hero model.

Amigo Hero 600 denier ripstop from Horseware is a tough, breathable, and waterproof outer material made of polyester that is woven in a cross pattern to prevent a potential hole from becoming a large tear upon light contact.

Cut at the legs for maximum freedom of movement.
Inner material of polyester to minimize chafing.
Front closure with 2 T-buckles and 2 cross surcingles under the belly.

Attachments for neck are available (not included), not compatible with the liner system.
