The Endurance Pack is a fantastic piece of gear to take you a long ways. But when the weather turns terrible, your gear requirements are larger, or if you just want to have the ability to hold more gear, we have a solution for you. This add on pack creates an additional 4 Liters of storage to the rear of the pack. It attaches via webbing at the top, and through the nylon web at the bottom. It's best for light jackets and layers, not heavy bulky items. 

Additionally, it comes with the shock cord and trekking pole hardware already attached. 

As an added bonus, you're not just adding another pack to your gear, you're creating a pack that can be used for multiple purposes. 

How to use it

Great product and customer service!

My version 3 endurance pack is by far the best hydration pack I've ever owned! It barely feels like you are wearing it! I also opted for the extra gear bag to stash a light windbreaker and I love that this vest doesn't bounce not only that but the straps across the chest aren't elastic like most vests or packs which eventually lose their elasticity. Overall I would highly highly highly recommend this vest and I would definitely buy it again and other products of Orange Mud.

It's good but

It's a good little add on pack, but the biggest flaw is that their is no way to close up the opening at the top. So depending on what you do, might have to watch nothing bounces out. Other then that great little add on, just don't put anything really valuable in.

If Goldilocks had a pack it would be this one!

Too heavy? Too light? The Add on Bag for the Endurance Pack solves the problem. When I want to move quickly over a long distance, but I want to have just a little bit more with me, this Add on Bag is the way to go. Add one of these to your beloved Endurance Pack and get your load “just right”. You won’t be sorry!

Zero bounce and breathable

I've used it on a full and a half marathon, and could not be happier. It rides high on the back so I don't get the chaffing in the middle back that I have experienced with other packs once I start sweating. The side cinch straps are helpful to keep it secure as you start consuming fluids and nutrition. Won't use another pack again!

Good add on idea

This was a good idea. I’m glad I got it with my pack. I use it on about half my runs if I need to take extra layers. I’d love to have a zipper or Velcro top to secure everything but it’s worked well so far.
