Yes & No
Sorry, it just didn't seem that the "vent" system worked as claimed once I got this pack loaded. I had wanted an AirControl suspension system and inadvertently ordered the COMPACT EXP.12 I liked the waist belt system and the layout of the different compartments, esp the pump pouch and hidden rain cover. As soon as this model arrived and I realized my mistake, I ordered the correct model (RACE EXP AIR) and did a load test/packing test side by side comparison. Fully loaded with my usual overkill of stuff plus filling the 3L bladder, I discovered the following: 1) a loaded EXP12 felt like a sausage on my back and the advantage of it's suspension all but disappeared. Same load on the Race EXP and I still had 1" TO 2" of open air clearance between my back and the pack. Just as I wanted. 2) Initially the COMPACT EXP appeared to probably hold more of my gear but I was surprised to find out that the RACE Air held everything, just in 2 zippered pockets instead of the more numerous ones in the COMPACT EXP. 3)Waist belt very nice as well as the adjustable ( up and down) chest strap. 4) the 2 side pouches should have some sort of way to cinch the top so items won't fall out accidently. Synopsis-hey Deuter, why not combine the advantages of the two packs for the bikers out there that do extended full day rides in the backcountry. You pack carries great but I could use 1 or 2 more compartments to separate out my gear,3 at a minimum. The small pouch on the RACE EXP AIR just barely holds a couple sunglass cases with a little room left over. This means I have to use the large pouch for spare tube, rainjacket, long sleeve shirt,lunch, camera, possibles" bag, binocs, tp. ALSO, how about some spare d rings/loops to attach extra stuff on the outside if need be. Your pack is extremely well made and I am looking forward to many trips with it. Keep trying!!
