The compression straps also double for storing your sleeping bag, tent, and rain jacket. Finally, there is a built-in rainfly in the special bottom pocket.

Gregory Inertia 20 3D-Hydro Daypack

best internal frame backpack - Gregory Inertia

Wondering what to pack can be tricky. Make sure to bring the essentials by season. For the fall and spring, it’s always smart to have a raincoat and a light pair of gloves on hand. Come summer, you can swap those items out for a swimming towel and suit. Here’s the best part. You can leave your bulky water bottle behind. The Gregory Inertia 20 3D-Hydro Daypack comes equipped with a reservoir for convenient hydration on the go.

Leave your water bottle behind and fill up with the convenient built-in reservoir from Gregory. Three liters is a good amount of water storage. If you are only going on a day’s hike, that should be plenty. However, if you know you will be drinking a lot more, you can supplement the reservoir with an additional bottle of water. And if you’re looking to cut the bulk of extra carrying altogether, bring a filtration straw. 

Nothing is quite as great as having a ventilated back panel in the heat of summer. We’re sure you’ve experienced back sweat when traveling before. Your pack is weighing heavy, you have been carrying it for a long time, and there is still quite a ways to walk before you get to your hostel. That creates a sticky situation. Instead of bearing the heat and discomfort, invest in a pack that supports your needs. With the Gregory Inertia 20 3D-Hydro Daypack, you will stay cool and dry on the trail or wherever you go.

Here is yet another important feature of the Gregory Inertia 20 3D-Hydro Daypack. Travelers often overlook padding when choosing their backpack. But good padding makes a world of difference. After all, you don’t want an aching back and straps that dig into your shoulders. These problems are more common than you would think. The padded, adjustable hip belt and shoulder harness transfer the weight of the pack off of your back and shoulders and down to your hips. Not only is this more comfortable but it also spares you from unnecessary back pain. It is the healthier way to wear a pack.

Travelers love the Gregory Inertia 20 3D-Hydro Daypack too. Even when the backpack is fully loaded, you won’t feel tired and weighed down after walking with it on. The hip belt makes it very comfortable to wear and the hip pockets are in a good location for easy access to items you may need.

In addition to the durable quality, the interior is so spacious. With interior dimensions of 20 liters, you will have plenty of room for the gear you need to bring. If you are considering investing in a high-quality backpack for the great outdoors, this is it. It’s not only highly adjustable but it also offers customization for nearly any physique.

Does it look low profile? Sure. Does it also work like magic? Yes. We swear you’ll forget you are even wearing this pack.

Gregory Mountain Baltoro 75 Liter Men’s Multi-Day Hiking Backpack

best internal frame backpack - Gregory Mountain Baltoro

There are multiple elements that give this backpack a custom fit. The torso length, hip belt size, shoulder harness size, and lumbar tune all come together to create comfort you’ll enjoy. When it comes to the pack details, weather shield pockets, u-zip access, a sleeping bag compartment, and more are all desirable features. The torso length measurement works well. The design ensures that the majority of the backpack’s load is transferred directly onto the hips instead of your back and shoulders. This makes it so much easier to carry and helps to prevent any injuries. The last thing you want to do is strain your body when you’re hiking and camping out in the backcountry.

Just like the hip belt size, the shoulder harness also offers a pre-curved ergonomic design. The shoulder harness straps are available in multiple sizes to accommodate all types of body shapes.

The removable EVA shim offers the traveler the perfect contouring in the lumbar region.
