An Overview of KUIU Pro Hunting Packs
KUIU founder Jason Hairston, an avid bowhunter himself, set out to create premium hunting gear that was lighter than traditional packs without sacrificing durability or practicality in the field.
The result was an extensive line of KUIU Pro hunting packs built with rugged materials like waterproof synthetic fabrics and carbon fiber frames.
Two of the standout models in the KUIU Pro series are the 2300 and 3600. Both packs utilize KUIU’s lightweight, minimalist frame design to effectively transfer weight off your shoulders while still providing structure and support. The iconic Toray fabric is water-resistant and quietly durable even in harsh conditions.
While the 2300 and 3600 share many of the same traits, there are some key differences hunters should be aware of when deciding between the two. The 2300 is the smaller, more nimble pack while the 3600 is designed for longer trips or packing out meat.

Key Differences Between KUIU Pro 2300 And 3600 Hunting Packs
Now that we’ve covered the basics of each pack, let’s compare them across some key factors hunters consider when choosing a hunting pack.
Weight
- KUIU Pro 2300: 4 lbs 7 oz
- KUIU Pro 3600: 5 lbs 3 oz
With nearly a pound difference in weight, the Pro 2300 is noticeably lighter than the larger Pro 3600. However, both utilize KUIU’s minimalist frame design to cut down on ounces without losing structure and support.
The Pro 2300 shines if you’ll be covering a lot of ground each day and don’t need the extra storage. But the Pro 3600 is still respectable for its size, keeping weight manageable even when loaded down.
Storage Capacity
- KUIU Pro 2300: 38 L / 2300 cubic inches
- KUIU Pro 3600: 60 L / 3600 cubic inches
The Pro 2300 offers a good mid-range storage capacity – enough for 1-3 days of gear but compact enough for mobility. The Pro 3600 provides nearly double the capacity. It can swallow multiple days of gear, cold weather layers, and plenty of meat.
Ask yourself how much cargo space and duration of trip you need. The Pro 2300 hits a nice sweet spot for many hunters, but the Pro 3600 is the choice if you need more space.

Comfort and Fit
Both KUIU packs utilize similar adjustable harness systems and padding that make the packs comfortable, even under heavy loads. Key features include:
- Padded and ventilated backing
- Adjustable shoulder straps with sternum strap
- Removable belt with pockets and gear loops
- Lightweight stiffened frame effectively transfers weight to hips
For users who carefully dial in the fit, both packs achieve an excellent comfortable carry. The Pro 3600 waist belt is a bit beefier for heavier loads. But neither pack should cause soreness or discomfort when properly adjusted.
Durability
KUIU built both models with rugged materials like water-resistant Toray fabrics, carbon fiber frame stays, and heavy-duty zippers that stand up to years of abuse.
Both packs should easily handle being dragged through thick brush day after day.
The Pro 3600 uses some slightly more reinforced fabrics on high-wear areas.
But both models are far more durable than comparable hunting packs from other brands.
KUIU’s focus on quality materials shines through.
Weather Resistance
For complete water protection, using an additional rain cover or dry bags inside the packs is recommended. But the coated zippers and special DWR treatment on the fabrics give you solid weather protection in light to medium precipitation.
Application and Hunting Scenarios
KUIU Pro 2300 Ideal Uses:
- Day hunts or overnighters 1-3 days in length
- Packing out small/quartered animals
- Early season bowhunting where mobility is key
- Mule deer, whitetail, or antelope hunts
- Hot weather hunts that require a lighter pack
KUIU Pro 3600 Ideal Uses:
- Extended backcountry hunts 5+ days
- Packing out elk, moose, or other larger animals
- Late season hunts in frigid weather where more gear is needed
- Spot and stalk hunts where maximum cargo capacity required
- Multi-purpose use for hunting and camping/hiking trips

Frequently Asked Questions (FAQ)
Choose based on the duration of your trip and how much gear/meat you need to carry:
1. 1-3 day hunts: 1900-2300 cu in
2. 3-5 day hunts: 2300-3000 cu in
3. 5+ day extended hunts: 3000+ cu in
In general, it’s better to size up if between two packs to have extra room.
KUIU Pro packs use water-resistant fabric but are not 100% waterproof. They withstand moisture and light rain but very wet conditions call for a pack cover or dry bag.
The suspension system and frames are built to comfortably carry up to 100+ lbs. But most hunters aim for a total pack weight of <40 lbs for mobility. Pack the lightest gear possible and only haul out as much meat as needed.
The internal frame and stay system weighs approximately 2.5 – 3 pounds depending on the size of pack. So you save nearly half the weight of an external frame.
Final Verdict: Which is Better for You?
For most well-rounded use, the KUIU Pro 2300 gets our nod as the best overall choice. It hits that ideal balance of carrying capacity, low weight, and rugged build. For hunts ranging from day trips to several nights out, the Pro 2300 has all the essential features without unnecessary bulk.
However, the Pro 3600 takes the crown if you need to haul heavy loads over long distances. The extra capacity and beefier construction make it ideal for remote hunts packing out large animals. It’s also a smart choice for any hunt where you need to carry 7+ days of supplies.
At the end of the day, it comes down to your specific needs and preferences. Ask yourself how much gear/meat you need to haul and how far you need to go. Use the 2300 for an all-around mobile hunting pack or go bigger with the 3600 if max capacity and extended trips are your goal.
Either way, KUIU’s hunting pack lineup has you covered.
