Introducing the Sawtooth Duffel Bags. Adventure-ready and built to last, these duffel bags deliver the durability and versatility you need for any journey. With three sizes from which to choose, you will be covered for any expedition. Constructed from tough, waterproof materials, it protects your gear from the elements while standing up to daily wear and tear. Reinforced handles give you a secure grip, padded shoulder straps provide all-day comfort, and multiple compartments keep everything organized and easy to reach. Whether you’re headed into the backcountry, traveling for work, or hauling gear to the gym, this bag has the strength and space to handle it all.
Waterproof
Removable Shoulder straps and Handle
Main compartment has Horseshoe-style zipper.
Side Pockets that reach half way through the bag on both sides.
The triaxial carbon fiber structure combined with additional strategically placed composite materials provides the greatest strength to weight ratio on the market. We are confident in delivering a frame that is not only comfortable, but provides the ability to haul extremely heavy loads.
The key to the frame’s design is its shape. This allows the heaviest load to be positioned in the center of your back by spreading the weight over your hips, minimizing muscle fatigue and shoulder strain. To stay cooler in hot conditions, the shape maintains air flow around your back. The frame also follows the natural curvature of your spine, providing extreme comfort in all conditions.
We offer a 100% lifetime warranty for any material defects and workmanship to the original purchaser. For any damages outside of normal wear, we can repair it at a reasonable cost.
The Integorus and Invictus Frames have a LIFETIME GUARANTEE.
Yes. All IA packs work off of a single frame and suspension system. You can interchange the bags and Pannier Load Carrier at will. No need to buy a separate suspension system.
The material we use is a 500D Cordura which is very water resistant but not waterproof. If your hunting in wet environment, we recommend out IA Rain Cover.
Yes. We have the Integrous Frame for torso lengths from 18-22".
And our Invictus Female Frame for torso lengths 13-17". This frame will also work for kids who fall into that torso length range.
It does come standard with the IA Day Pack, but it does not come with the IA3K, the IA5K, or the IA8K Pack Systems. The Pannier isn't required for packing meat, but we definitely recommend it.
Took the Sawtooth Duffel out for its first true Alaska backcountry test, and it crushed it. I pushed it through bogs, heavy mud, and deep water crossings on the way to camp. Everything inside—clothes, dry layers, and gear—stayed completely dry thanks to the solid waterproofing. The bag held up perfectly under real abuse with no rips, seam failures, or leaks.
Once back at the house, I just hosed it off, let it dry, and it was ready to roll again the same day for my daily training. The versatile carry options (handles and removable padded shoulder straps) make it easy to switch between backcountry hauls and gym runs, while the organization and U-shaped zipper access kept everything quick to grab.
This thing is built tough for the kind of wet, rugged conditions we deal with up here—highly recommend it for hunters, outdoorsmen, or anyone needing a reliable, multi-use duffel that transitions seamlessly from the field to everyday life. Solid 5-star performer!

The 70L duffle worked out great and stood up to being treated tough. I really like that it has multiple compartments to separate dirty from clean clean clothes and store shoes without the dirt and smell getting to the clean clothes in the main compartment.
We will be ordering another duffel!

This is the best duffel bag I’ve ever owned, hands down! There are so many zippered pockets, it made it easy to organize my belongings. Being able to wear it as a back pack was also a game changer going through the airport! Well done Initial Ascent!

Awesome bag for the price. One of the best built on the market too!

I used this as a carry on to go to Peru with. It was really nice to just throw in the back of a truck and not have to worry about it getting dusty or wet. The construction is really high quality.

Wish thr lid folded out for a standing mat other than that all I could've asked for

The perfect everyday duffel. Exceeded my expectations.

Love the duffel. Bought it specifically for my 2026 DIY fly-in Moose Hunt to carry more stuff overhead on the commercial airliner with the 40L size as well as the bush plane. Am using it for work to carry my workout gear and duty gear. Built like a tank and love the modularity of it. Highly recommend it. Might be a little pricier than some other similar sized waterproof duffels out there but those others in my personal opinion are not designed as well. I own a lot of IA gear and it never let's me down. Looking at getting the scout pack as well. Thanks again for taking care of military/first responders guys!!!

AMAZING Gym bag and addition to the larger bags for more organization during longer trips such as camping, hunting, and other trips as well. IA knocked these out of the park.

These are a must have for camping, hunting, or travel in general! Durable and waterproof, CAN'T BEAT THEM!

The team at IA nailed it with these duffels. After a long time of making do with others we finally have a bag that does everything I was looking for!

This bag is great! Well built and has the necessary compartments to keep you organized. Having space to keep your dirties separate from your clean clothes is huge. Big fan of this bag!! Initial Ascent for the win…again!

I love it. Waterproofing comes in handy and the ability to organize everything is more useful than I originally thought.

Used my duffel for a 5 day work trip to Denver and I felt sooooo cool walking through the airport with a mountain dude on my back. 😃
