Atlas Trainer Frame System
Comfort ≠ Compromise
Ever trained with rocks or sandbags in your pack? We have too. Although our packs are great for that, we decided to save our hips and knees with a much better way to simulate the loads we carry during the season.
The Atlas Trainer attachment can securely carry up to 90 lbs. of barbell plates and is easy to install on an Outdoorsmans pack frame. Utilized by world-renowned hunters and professional athletes, the Atlas is the ultimate leg punishment tool.
Comfort often requires compromise, the Atlas trainer is the exception.
The Atlas Trainer Frame System comes to your door fully assembled and includes the Atlas Trainer with Oso barbell collar, frame, belt, and harness. (45lb weight not included)

"My wife and I both purchased Atlas Trainer packs and absolutely love them. They're extremely comfortable and well made. The adjustability is also a huge bonus. We've been using them regularly and have had no issues at all. If you're looking for a good pack to do some ruck training with, this is it."
1. LOAD THE WEIGHT
Secure standard Olympic weight plates directly onto the Atlas Trainer’s frame for a stable, balanced load.
2. STRAP IT ON
Adjust the harness for a comfortable, dialed-in fit that keeps the weight close to your body.
3. START MOVING
Walk, hike, climb, or train. Every step builds strength, endurance, and grit.
4. PROGRESS OVER TIME
Add or remove weight as you get stronger. Simple, measurable progress without guesswork.
Our patented frame system is rigid with a twist. The advanced polymer frame is designed to flex with body movements but rigid enough to keep plenty of weight in place.
This specialized material pairs a tough 600D Polyester base with raised texture dots that offer a breathable grip, helping to keep the lumbar pad positioned where it needs to ride on your body. This material is extremely durable — resisting abrasion, water, and stains.
Superior Comfort
We make things that work better and last longer. Our products solve real problems with clean design and honest materials.
Shoulder Harness Spacer Mesh The 3D Spacer Mesh material provides comfort, support, and breathability. The polyester yarns feature an antimicrobial to inhibit the growth of odor-causing bacteria and are built with a proprietary moisture-wicking technology that moves moisture up to 6x faster than standard nylon or polyester fabrics, helping to keep you cool and dry as you wear the pack.

We back our frame and suspension system 100%. If it happens to fail, we will replace it immediately. No questions asked (unless there's a cool story).
Try it for 30-days, if you can't handle the load send it back and we'll give you your money back.
The Atlas Trainer is built to safely carry heavy loads (up to approximately 90 lbs, depending on setup). It’s ideal for beginners and advanced athletes alike, thanks to its scalable loading system.
The Atlas Trainer is designed to hold standard Olympic weight plates. This makes it easy to precisely control and progressively increase your training load using plates you may already own.
Yes. The harness system is designed to distribute weight efficiently across your shoulders and hips, reducing pressure points and minimizing load shift during movement even on longer walks or hikes.
Unlike standard backpacks that rely on loose weights or sandbags, the Atlas Trainer mounts weight plates directly to the frame. This keeps the load stable, balanced, and close to your center of gravity—making training more comfortable, efficient, and repeatable.
