This is more of what I am looking for. than you for the suggestion. You said you had one currently? any chance you can take a few pics of it? maybe show the compartments? I hate when online sellers only show the one pic of the bag.http://www.galls.com/style.html?assort=general_catalog&cat=&style=MB028
I used a earlier,slightly smaller version of this pack for years.It is basicly the same as a thomas aeromed pack but about 20% the cost.Great design and plenty big for a car kit.
I used it from 99 to 04 when I got a larger pack.When I upsized( Medic means more gear,or so I thought at the time),I gave the pack to my partner.It was the same basic layout without the side pouches and the front bellows-type pocket. There is one pic with the pack open on the link,but if you google" thomas aeromed pack" it is very similar in layout.The inside is two clear front zipper pouches the width of the compartment(secured to the bag with velcro) ,the lid has one leaf with velcro attached pouches as seen on the link and other slot type pouches(some clear some not).Mine didn't have the side pockets but they may have clear velcro pockets inside(thomas has some and some elastic).The bellows front pocket is just a big open pouch if it folows the thomas pattern. The top ouch may or not have the clear velcro pouches(mine was just a simple zipper clamshell type pocket). Lastly under the shoulder straps there is another slot pocket.You said you had one currently? any chance you can take a few pics of it? maybe show the compartments?
