Can I use this for hiking?
Junhao Lo –
Thank you for your review, Natalie! The Poseidon Compass Cirrus Cover + Holster is designed to be a versatile accessory. While it’s primarily meant for compass protection, its durable design and secure strap make it suitable for various outdoor activities, including hiking. However, please note that it’s not a backpack or a storage container, so you can’t carry a lot of gear with it. It’s more of a accessory to keep your compass safe and within reach. If you have any other questions or concerns, feel free to ask!

It has 4 waterproof pockets, does that mean everything inside will be dry even if submerged in water?
Junhao Lo –
Thank you for reaching out, Aiden! The Poseidon Compass Cirrus Cover + Holster indeed features 4 waterproof pockets. However, please note that while the pockets are designed to keep contents dry in case of accidental submersion, they are not entirely impermeable. For optimal protection, we recommend avoiding full immersion for extended periods.

The cover works perfectly and the holster is strong too. However, the stitching inside the pockets could be tighter.
