Archelon Waterproof bag
Love it. This is my second bag and I wouldn’t choose a different brand to go with.

Awesome dry pack
This pack is outstanding. I used a dry case prior to this and it didn’t even compare.. This pack has much more room, far more functional, and it has actual usable pockets in it.. it’s nice to know my stuff will stay dry in the rain or if I drop my pack in the water..

Awesome dry pay
I have been searching for a quality 100%. waterproof backpack since my last pack started leaking. I was using dry case prior to this.. The Hella Dry backpack is top notch, compared to dry case. It’s bigger and I trust it more. Tthere are more pockets to store gear inside and on the outside.. It’s nice because you can literally float your backpack in the water next to you and know that your stuff is going to be dry on the inside. Love it.

Unexpectedly good
I’ve been using this backpack for two years packrafting and duck hunting and it’s been working great. Last weekend I forgot my marsh stool and the backpack was so airtight I sat on it for 4 hours and it held air except for two refills. I wouldn’t recommend it for this purpose cause it’s pretty hard on the seams but great on a pinch. Only complaints are the water bottle mesh holder is built for a capri sun, not a water bottle, and the grab handles are unnecessarily large and heavy but not a significant negative

Durability/Versatility
My OG 28L has seen some stuff and still keeps rolling. From the field, marsh to the flats and open ocean this thing has survived/thrived in the mud, muck, storms and scary seas while keeping my gear completely dry and readily available. An essential piece of gear that absolutely has no quit!

Absolute must have!
100% waterproof is correct! no worries of any water getting in, like the extra zipper pockets inside and out. Holds all your gear and necessities. my go to bag when guiding.

Best got Better!!
Not sure how Jordan and Jason did it but they made an already incredible product even better. The improvements from the Tortuga to the Archelon not only were essential but are perfect! Great job I love this bag!!
