Ortovox Haute Route 40L Backpack question

[moops]

Is anyone using this or a similar Ortovox pack?

I'm currently using (for the last 4-5 years) the Mammut Nirviana Pro (35L) and the zippers and material are pretty burly. I was looking for a little larger pack for longer multi-day (not expeditions) tours that will provide space for a sleeping bag and more food.

The primary feature I HAVE to have is back panel access...can't live without it.

I just picked up, from BC.com, the Haute Route 40L but the zippers seem frail (small and "catchy") and the material feels odd compared to what I'm familiar with so I'm reconsidering my decision.

Am I being too critical of this pack? What is your experience with the Ortovox packs?

Adding to the equation, my second choice was the Osprey Packs Kamber 42L.

Thoughts?

Thanks guys!

I’m easy on equipment, but I’ve had a Haute Route 45 for a few years and it’s great. Fits well; low profile for holding as much crap as it does. No durability or zipper issues yet. Can’t speak to the newer 40L though.
