    So awesome!

    Bobbi and Alli make awesome gear, and this dry bag pack is exactly what I needed for a versatile piece of river and all around gear for use as a professional guide!

    Well made and a pleasure to use

    This is my 2nd Altrus backack. I use them to carry my inflatable frameless pontoon boats (40 lbs. with gear). These are the perfect size and construction, everything about them is quality from the material, the welding , harness and buckles. After hiking into the river and assembling the boats, the bags make perfect waterproof storage bags for a day of fishing. These things are bomber.

    Guided trip recommended

    We ordered this bag for a guided trip we had planned and it was the 115L was the exact size recommended. The bag feels very tough compared to other dry bags I've seen. All the straps seem to be welded, I didn't see any sewing done. This actually made the straps strong, it held up really well even when I filled up the bag completely full of my clothes and belongings. The middle buckle is high quality, it's some sort of metal. Overall, you can feel the quality and workmanship that went into this bag. Oh and the straps are all removable which was nice when I didn't want it to get caught and swing around during the trip.
