35 Years of Helping Paddlers Discover the Joys of Portaging

We’ve been tripping with our families since we were kids.

And got so fed up with uncomfortable canoe packs and nasty barrel harnesses that Bill just had to design a solution.

He first looked to backpack designs for inspiration. The result was:

  • the first-ever internal frame portage pack. (So impressive with heavy loads.)
  • the first barrel harness with a contoured foam back pad and Upper Adjustment. (Game changer!)
  • and the first to offer custom-fit … because carrying 50+ lbs in a one-size-fits-all pack is unnecessarily painful.
“It was a blast being the lead designer for the Canadian Armed Forces Rucksack and Small Pack System. We used scientific research and field testing to fully understand how pack design impacts load carriage, load control and weight transfer. It dramatically changed my approach to design. Custom-sizing does matter.” Bill Ostrom

All Your Questions Answered.

Is the custom-fit worth the investment?

A pack or harness that is custom-fit to your body means you will be more surefooted and comfortable on the portage. You can be confident in getting out summer after summer, perhaps on more challenging trips. (Quetico or the BWCA anyone?)

Here's something else to think about. Portages will get harder as you get older. (Trust us!) Your pack will feel heavier and the smallest twist of an ankle or knee on the portage could wreck your entire season.

“We loaded the pack up to about 55-60lbs and my husband helped me get it on my back and tighten everything up. It was a dream!!! No more pain on my neck and shoulders from ill-fitting straps, and a waist belt that actually came to
my waist and tightened up, and stayed in place. The portaging was SO MUCH EASIER for me!”

Think about your next 30 summers. How does that return on investment sound?

Are your packs waterproof?

Our packs are not waterproof, but we highly recommend waterproofing any gear inside your pack that absorbs moisture (clothing, sleeping bag, sleeping pad, repair kit, personal kit, etc.).

Options are individual dry bags, a canoe pack liner, or stuff sacks lined with two layers of good-quality garbage bags (individually sealed).

Why are your packs heavier than others?


The interchangeable shoulder straps and hip belt, and the adjustable torso that allow these packs to fit your exact body shape, all require extra buckles, fabric, webbing and reinforcement.

You’ll notice that the advantages of custom-fit outweigh the cons of a little extra weight.

Imagine feeling more comfortable, surefooted and confident on the portages. And wanting to go even further into the backcountry.


Yeah, we took a hard look at ways to reduce weight…but it meant compromising on durability.

Just imagine shaving a couple of ounces only to have your pack bust apart.

Check out the extra fabric and webbing to reinforce the suspension system and high-stress areas.

Making sure you have a pack you can rely on in the backcountry is the backbone of our Forever Warranty.
