35 Day ChallengeArticlesThe Lightweight Philosophy

35 Day Challenge

Sealline 35HD Boundary Waters pack is the perfect pack for ultralight paddling trips.

The challenge is simple: Come up with a gear system that fits inside a SealLine Boundary 35 Day Pack which maintains a decent level of comfort and can handle a solo trip to an area like the Boundary Waters in late September or early October.

Why the 35 Day Challenge? Simple. The 35 Day Challenge is engineered to challenge your perceptions as what is possible when traveling by canoe. A small waterproof pack, like the Sealline 35 Day Pack can be used to carry everything you need for a backcountry trip. And you’ll still be comfortable while doing it. The pure pleasure of reaching the other side of the portage without having to go back for a second trip and not feeling strained under a pack and canoe is more than worth giving it a try.


  • Must have a shelter, and sleep system.
  • Must have a cook system and water purifying system.
  • Must have clothing to cover temperatures from 32°F to 80°F. Must handle conditions from sun to rain, sleet, hail, and snow.
  • Must have a compass.
  • Must have 5 days and 4 nights of food. A menu is a must.
  • Must have a bear proof food storage system.
  • Must fit into a Sealline Boundary 35 Day pack.

You can assume the following: Your canoe is stocked with a seat pad, two 30 foot painters, two paddles (one bent, one straight), and a life vest.

Sample List

The following list is the gear that I used on an overnight trip on the Vern River Route in the Boundary Waters. I had planned on a two night trip, but decided to cut out early the second day. There was enough room in the pack for three more days of meals, but not much else. I also carried a tripod inside the 35HD pack which isn’t included in the gear list below. My camera was carried separately in a Sealline 10HD. I carried a Nikon D70 and two lenses plus a couple of filters, memory cards, and an extra battery. When doing portages, I strapped both spare paddles into the canoe, threw the pack on my back, hoisted the 32 pound Bell Magic on my shoulders, and carried the 10HD in my hand. This made for fast single carry portages, which was a real plus while bush whacking and on the 240 rod portage.

This list itself is slightly heavy. There are several places where I could improve it, and these include a reduction in weight in clothing by probably a pound by upgrading to newer and lighter and warmer items. The shelter and bag system could also probably be reduced in weight. By switching to a lighter new and hightech tarp bivy sack system I could shave a pound off, and another half pound could come off of the bag. I went a little heavy in the kitchen also on this trip, because I didn’t feel like using a pop can stove. All in all, I could probably easily drop 3 to 4 pounds out of my pack, and if I was really trying, I could drop it down to 8.5 to 9 pounds before consumables.

A few other items of interest are my canoe and paddles. I use a ZRE Lightweight Carbon Bent Shaft which comes in a 8.5 ounces, a wood paddle which is 1.5 pounds, my Bell Magic outfitted with the seatcover, painters and bungies is 32 pounds, and my lifevest is a Stohlquist Brik, which doesn’t weigh very much at all.

All in all, this is a pretty plush and all around kit for early spring and late fall travel. In the above picture, you can see everything that I carried, except the camera and 10HD bag it was carried in. The picture below is a tarp set-up that I’ve been using lately. It’s easy to set-up, weather proof, and only requires 4 stakes.

  • […] Well, I wanted to test how well cell phones would work for me in the Boundary Waters Wilderness Area, maninly because family members (Who can argue with their mom, right?) expressed concern that I should be carrying a phone with me on my solo trips, so on my last trip I brought one with me. If it worked, it would become standard gear in my pack (My Gear List). […]

  • I like where you’re coming from with this Bryan. We’d cut down our gear considerably from when we paddled the Mississippi River, and we were already going fairly light. More gear = more hassles.

    Oh yeah, I live in my Marmot Driclime windshirt at least 10 months of the year. It’s by far my most-used piece of gear, and holding up strong for over 9 years now.

    Take care,


    • I love my Driclime. I’ve had it since probably ’98, and the zipper gave out last year. I sent it in to Marmot and they replaced the zipper with no questions asked. I’m sure they would have given me a new one if I had wanted it. They’re a stand-up company that builds the best coat.

  • Great post, and happens to correspond with my renewed commitment to go light. Unlike most canoe trippers I know, I began by going light, but as years passed my load got heavier and heavier. Currently, spending the winter reverting back. No knife or hatchet/saw though. I consider these essentials.
