The ripstop polyester shell material is durable and resistant to tears, making it a reliable option for rough outdoor conditions. The included compression sack allows for easy packing and compact storage, which is a big plus for those needing to save space in their backpacks.

However, some users might find the mummy shape somewhat restrictive compared to more spacious designs.
