I have been using the exotec chest protector/dakar pack. Great piece of kit! so nice to finally have an integrated solution to this and not have to hodgepodge together various bits that never work well together. It fits well, stays put and has plenty of room to store the essentials for long outings. It is solid and well built. I would like to see some more compartmentalization in the packs storage areas but that is a minor gripe. I look forward to seeing what other products they add to the lineup. Keep up the great work! 
- I've had my Zac Speed pack for over three years now, around 200hrs of Enduro type riding in all kinds of weather. It's carried my tools as trail mechanic for our group rides and camera gear, kept me hydrated and is still in great shape. All clips and buckles still work, the zips still run smooth and it still keeps out the elements on a ride. I'll be upgrading to the newer pack with the front Rally pocket system and passing my old pack to my adult son. Definitely get yourself one of these quality backpacks
- Best backpacks in the world! Interchangeable components are brilliant, can't wait to see what else they bring out.
- Gear worth every penny even if you have to get the blokes to ship it to ya! Representing in the Pacific Northwest, WA State, USA
