SealLine Boundary Dry Pack

This hard-wearing bag isn’t designed just for the canoe, kayak, and SUP- an integrated suspension system with substantial shoulder straps helps move your gear on planes, trains, and automobiles. Although the function as a dry bag is great, the shoulder straps aren’t adjustable for different torso lengths. This product is ideal for the passionate active person who is looking for a quiver that can hold several different types of ‘arrows’.

Built to be a multi-purpose pack, the SealLine Boundary Pack aims to check A LOT of boxes for the avid out-of-doors person. SealLine, a subsidiary of Cascade Designs, began making dry bags in 1986 featuring the common ‘dual-strip closure’ we see in many dry bags today.

This pack has proven to be waterproof throughout the course of testing—both on land, and on sea. The SealLine Boundary has seen rain and nearly two dozen outings, without any moisture infiltration. It should be noted that no "dry" style bag is considered 100% waterproof, and should not be expected to keep valuable contents safe, especially in the case of submersion.  

As a dry bag for water sports, this pack is really great. Robust construction, the Boundary is built to last for decades.

 Several seasons of testing has shown little to no observable wear.  

Loading and securing the Boundary Pack is practically the same as most dry bags on today’s market, and this system has long been proven to be tried and true. Beyond the removable shoulder straps, this is your typical basic dry bag. 

Regarding hauling light loads, this pack does the job. Seal Line has recently replaced the Boundary Pack with the Black Canyon Pack, adding a well padded waist belt. A link to the new model can be found here. 

The gripes begin when longer haul times, or heavier loads come into play. This model has a basic nylon strap as a waistbelt.

This review is not rated based on this waist belt strap, as SealLine has improved the design. Although the shoulder straps are well made and comfortable, there is no torso adjustment whatsoever with this pack—either on, or off.

Many other packs have had a "ladder" type of system to accommodate this, and it would be excellent to see this addition, especially taking the pack’s $280 price into consideration. It also appears to have been an oversight when designing the load-lifter straps- these straps don’t have a serve-able function, unless this pack is very full. 

Removing the backpack straps is quite easy, following a pretty straight-forward designed set of instructions. It is very nice to see these sewn onto the body of the strap assembly. 

Re-installing the shoulder straps is NOT easy. Between tight clearance, a plastic clip that allows the nylon loop to bunch and obstruct the ‘eye-of-the-needle’, and the velcro reattaching when hands are full can be frustrating. 

The SealLine Boundary Pack 65L has been tested for just under a year, and the durability of this product passes with flying colors. The pack has been used for general day-to-day use, car-camping for a medical First Responder recertification, many SUP excursions, and several day hikes. Many thanks to the people over at SealLine for the opportunity for the TrailSpace Gear Review Corps to test the SealLine Boundary 65L Pack.
