Survived Grand Canyon, T rats

  • Familiarity: I've used it several times

Just used on 2 night Grand Canyon backpack trip. Worked great and survived several assaults by the fat tree rats in the canyon, forgot to empty out snacks in hip pouch. They partially chewed through the pocket mesh but it was still usable for my cell phone and other snacks.

Suspension system worked like a champ, didn't feel uncomfortable at all on the hike down Kaibab and up Bright Angel. Little to no back sweat from pack even at 107 degree temperatures at bottom. Belt was very comfortable navigating over mule sized steps up and down and hopping / climbing rocks and boulders.

The only minor improvement I can think of during the trip was a zipper or something at the bottom of the pack to get my tent out without emptying out my pack and using the same material as the stuff pockets for the top flap pocket (stretch). Also, the water bladder pocket inside the pack may benefit from another redesign, the anti slosh tightening cords do get caught up on gear as it enters and leaves the main compartment.

Stuff pockets on sides and back worked great to squeeze in extra gear, water, water filter without any damage even during repeated dunkings, drops on rocks gravel and sand.

Pack worked great for GC for 2 nights packed wisely and I would not hesitate to recommend to others.

Make like mule droppings and hit the trail.

Excellent design for specific activities

  • Familiarity: I've used it several times

This day pack has all the makings of a great backpack for quick excursions. Every component seems to be designed with workmanship and quality materials. I'm really liking the lumbar support pad at the bottom of the frame sheet, which allows you to carry large, awkward loads comfortably.

I will say though that the pack is designed very specifically for backpacking and hiking. Because of the tall framesheet, the pack isn't suitable for biking and can be a little strange if the pack is only half loaded with gear.

As the description says, it's a fantastic technical pack that serves it's designed purpose well.

Great early effort from SD

  • Familiarity: I've used it once or twice and have initial impressions

I have been a longtime fan of Sierra Designs tents and sleeping bags, but have not yet tried their recent foray into packs. The Discovery is a great first effort with a simplistic design, great vented back paneling, innovative single DAC aluminum frame, and lots of external carrying space. This is a great option for someone needing a day-tripper that can haul mid-size loads in a variety of conditions.
