Rated 5 out of 5 by from Nice pack I really like this pack! Lightweight and comfortable. Only concerns are the mesh pockets seen a little thin and I wish the waist belt was just a little wider webbing.

Rated 5 out of 5 by from Fantastic Backpack I am a huge fan of this brand of backpacks and was very pleased to receive one in this quarter's Cairn Obsidian. The pack is light, yet sturdy and provides many pockets to put my gear.

Rated 5 out of 5 by from I love backpacks. Maybe a little too much as I have too many, but getting them is always very exciting to see all the features they have to offer, and the way they are built. This is one of my favorite backpacks

Rated 5 out of 5 by from review Been using it up at Big Bend and it has been really great. The fit is perfect for me! I enjoy the smallness of the bag, but that it can still hold a lot of stuff in it.

Rated 3 out of 5 by from Why is this so hyped up? I was a little disappointed, this is 2 liters larger than my usual day back (which I honestly have taken for pretty long trips and been happy with) but I found this pack to feel smaller than that and the storage pockets lackluster. While I like it and am keeping it, it's probably not going to replace my go to is bag.

Rated 4 out of 5 by from Thought there would be more room THere isnt much room in the backpack if you are using a 3L hydropack and I thought there would be more room to put things in the pockets on the outside. It is still a great day pack for smaller hikes.

- + Size Guide

Gregory Men's Packs

Gregory backpacking packs are available in a size range. Please check the PRODUCT FEATURES and / or SPECIFICATIONS for the torso range measurements of each size of a pack. The steps below are a guide for measuring your torso size.

The hipbelts on Gregory backpacking packs are adjustable to fit a range of sizes. A simple rule of thumb is that the ideal distance between the ends of the hipbelt pads after tightening should be 3 to 5 inches. However, the most important criteria are that the hipbelt wraps clear over the side of your body and that it rests 1 inch above your iliac crest. This allows proper load transfer to your skeletal structure, which maximizes comfort and minimizes energy expenditure.


HOW to MEASURE TORSO SIZE
1. Put your chin to your chest and feel for the big bone protruding on your neck at the top of your spine. That's the C7 vertebra.

2. Feel your hip bone, the top part of this is your iliac crest. Find the spot on your back that is level with the top of this crest.

3. Have someone measure the distance between these two points, following the contours of your spine.
