Nice overnight pack

This pack is quite comfortable to wear. I have not had the opportunity to wear it for an extended hike, but I am confident it will remain just as comfortable. Plenty of room for an overnight trip.

A light weight hauler - not worthy of "stout."

Photo shows seam failure with 30 days of trekking. Exact same on both sides. Luckily it was easily sewn up at a shoe repair shop. Design is ok, except for the top cover. It definitely needs a longer length or an extension. I swear by my large Gregory expedition pack. The stout pack is just an economy day pack.

How can such a small pack carry so well?

This pack carries like a bigger, badder pack. I have carried a similar size bag from Gregory, the Targhee, for a few seasons and used it in summer, despite its obvious construction for winter. It carries things the way I would like but summer time objectives require different gear. I am able to carry camp and food for 3 days in this. Granted, much of my gear is for 40°F or warmer and very compact. For my first adventure, shortly after I purchased, I had to climb 3,000' starting at 7,000'ASL over 5.5 miles. The pack weighed in at 34 pounds with 3 liters of water and food. I'm 5'8" with 17" torso measurement. I have the pack adjusted for the Medium harness sizing. Steep hikes demonstrate just how comfortable a pack can be, at least to me. Despite sizable step-ups onto rocks on the trails, this pack remained comfortable. It carries well and left me quite surprised over the course of my climb to camp. The back panel remains pretty cool but the weather was also cool. I could see during hotter weather this causing some heat build up on the back panel. Load remains stable. Once the straps were all adjusted I didn't adjust during the entire trip. My trip out was much lighter going down the same trail. I never noticed the pack. It was more comfortable as it was lighter by about 3 pounds. Some reviews talked about the cross-torso strap moving on them, I did not experience this problem. In fact, I've found very little to complain about with this compact pack. It is a big daypack by definition. But if you pack right and have the gear, this can do for a couple nights. I'm only one trip in with it. I'm curious to learn how long it will last. NOTES: This particular trip I was able to substitute the tent and stove for amateur radio equipment which is much heavier given the amount of metal.

Great pack for a weekend camp

Plenty of room to carry all the essential needs for a weekend camping trip. Very sturdy and sat very well on my shoulders and hips during the steep climbs.

Great pack

Fits close to body. Feels more agile than most packs. Perfect for fast and light weekend trips.

Great pack for scouts

This is a great pack and price point for fitting a teen scout. The waist and shoulder straps are a bit larger than similar packs in other brands, which was very helpful. The water bottle access is great, and I love the built in rain cover!

Stout 45L

I took it out for the first time today. I love it. 8 miles with 15lbs weight in it. Didn't even feel like I was carrying anything. I was once torn between osprey or the Gregory. I'm sold on Gregory from now on. Love the color too!! Thank you!!
