Leatt GPX 4.5 Hydra Chest Protector

A whole new classification of product. The Chest Protector 4.5 Hydra combines real chest and back protection with a backpack and hydration system that harnesses securely and comfortably to your body.

Harness the system on your body for a secure fit, then use the quick-adjust straps to attach the front chest plate where it fits you best.

The backpack itself features Leatt's top of the line CleanTech 3 liter bladder with quick detach hose which rests in an insulated compartment. It also has pockets and compartments for virtually anything you need for a long ride. Great front venting is coupled with ribbed AirLine air channels and mesh to help keep you cool even on the hottest days.

Great idea, really bad execution!
I was very excited when i saw this product as the concept is great, roost protector and Camel back/backpack combination.
The roost protector is ok, but the straps on the shoulders are very flimsy and do not work when you have the 2L camel back full and have some tools/gear/snacks in the backpack. The weight of everything is held by the shoulder straps and they are not very comfortable or sturdy to hold the weight of everything. and the side buckles that attach to the roost protector do very little to keep the weigh in a comfortable position. Its like having a backpack with really bad shoulder straps and trying to secure it by just using the waist belt. I think my prior combination of a Fox Roost Protector and a separate, Camelback/Backpack worst better and is way more comfortable for long rides, specially with the camelback full ans some gear. Would i buy again, NO. In fact i wish i could return it, but its been used so no luck with that.

What's the difference between the GPX version and the standard? They have the same description.
A shopper on Dec 14, 2017
This uses the description for the 4.5 hydra yet it appears dramatically larger. The bag looks identical to the GPX hydration carrier that is 25l not 10l. So....what is it?
A shopper on Sep 13, 2017
Does this work with a Leatt Neck Brace?
A shopper on Jul 4, 2018
Is the color the red white and black as shown in picture? Or is it black and white like the color description? I know there’s another color it comes in with no red in it.
