This 37L day pack is a workhorse! Big enough for snowshoe outings and travel, yet small enough for the lighter gear of summer? Go from the portage trail to Peru with this top-loading day pack that compresses down to 20L in a flash. The Aurora is a perfect carry with your canoe or as a kid’s portage pack. Love to travel? It fits most airlines' carry-on luggage requirements. We’ve tested it on canoe trips, 3 months of travel in Ecuador, and 30 days on the Camino de Santiago.

Perfect Fit Shoulder Straps in 1 Easy Step

Discover the One-and-Only Load Control Pocket.

You’ll be able to explore all day!

There is nothing worse than your heavy water bottle and lunch sinking to the bottom of your pack as you walk.

The Load Control Pocket is revolutionary. It’s about 4L in volume, (think 3 bags of milk) and is sewn into the top/back of the pack.

Right against your shoulder blades.

We’re always advising people to place their heaviest, densest gear “high and tight to your back” for the most comfortable carry.

This pocket enables you to do just that.

Load Up and Go

Are you ever surprised at how many “essentials” you need to carry in your day pack?

 …water, lunch, snacks, first aid kit, rain gear … an extra layer.

And we all know gear grows exponentially if you’ve got kids. Turtle stuffy anyone?

Whether you’re day-hiking sections of the Bruce Trail. Or need a portage pack for your fishing tackle and rain gear.

The Aurora day pack provides the perfect combination of functionality and comfort.

Aurora Day Pack

Bought the Aurora Pack specifically for a trip to the Azores. The pack doubled as my carry on luggage for the plane and a day pack for hiking. The backpack was very comfortable and looks and feels really durable.
Great back support with the removable aluminum frame, fully adjustable straps for a great fit and internal pockets to organize your load.
Another quality pack from Ostrom Outdoors.

You Know You Want this day pack - what's stopping you?

We're here to answer your questions!

Are your packs waterproof?

Our packs are not waterproof. And 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).

What if I make an error in my sizing?

Reach out! We send you instructions on how to check the fit.

Our custom-fit promise means that we’ll work with you to
make sure you have the right sizing.

Our shoulder straps and hip belt are interchangeable and easy to switch out. (We even have video instructions!)


We cover all shipping costs.

Is 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?

What’s the warranty?

Our Forever Warranty means that our products are warrantied to any owner for the lifetime of the product against defects in materials or workmanship under normal use.

If your Ostrom Outdoors product fails due to a material or manufacturing defect, we will repair or replace it at our option.

35 Years of Helping Paddlers Discover the Joys of Portaging

We’ve been canoe 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
