Size-chart

In the figure above, model A is 5'5" is wearing a small 25L bag.  This pack sits snug on her backside. These backpacks run small and are perfect for the day to day grab bag, over one shoulder or grab and go handle. Best fit over both shoulders on a small frame.  While it will fit your gym essentials, a laptop, cell phone, and accessories, others may want to pack that, and more. Fits perfect under seats for air travel too. Currently 65% Females have order this size. 

Model B is 6'1" is wearing the the large 45L bag. This backpack is significantly bigger allowing you to carry all of your essentials and more. Gym belt, laptop, shoes, pre-workout and great fit over both shoulders.  If you're looking for a large backpack this one is for you. Meets carry-on luggage requirements as a perfect fit for the overhead compartment.  Currently 75% Males have ordered this size.

 Both tactical bags are compartment built, so keep in mind its built to keep your gear separated, not having one large opening which makes some backpacks appear bigger. 

Our expert advice; if you don't want to worry about a lack of space, and you're someone who likes a bigger gym bag, the 45L will be great for you. If you're someone who likes to be a bit more nimble, and not pack the entire closet, the 25L will be a great choice!

If you're stuck between the small 25L and the large 45L then our NEW 35L is perfect for you, same style and not too small or not too large. Our Perfect pack!  Currently 50% Males and 50% Females have ordered this size.

What's the difference between a Traditional Backpack and a Meal Prep Management Bag?


Your Traditional Backpack is just that, the front pocket is your standard pen, business card pocket.  
Your Meal Management WOLFpak has the same outside design as the Traditional Backpack, however the front lower pocket is built as an internal insulated pocket, which includes 3 large meal containers, ice packet and plastic utensils.   You can also upgrade to our smaller meal containers and fit more meals into one along with our stainless steel utensils. 
Below is our Meal Management WOLFpak, the meal container will go into the middle compartment, and you have the entire rear compartment available to keep all your gear separate.
