Bought this one last season as my new alpine and backcountry touring backpack for 90 Euros (~100$).
First thing I realized, after I ve got it: All zippers are fully taped (compared to Dakine backpacks for example) except the zipper for the helm net.
This backpack has tons of (hidden) leashes and straps for skis, poles, helmet and ice picks. Plus a string for fixing the skis, when you use the "A" carrying method.
You can reduce the backpack's volume to ~15l with hooks. The front compartment has leashes (inside) for your probe, the shaft of the shovel and a small net pocket for your BC medic kit.
You can carry your skis either at the sides. Best way when you re climbing. Or fix them diagonal. Works rly well too and it s easier.
The Taos fits reaallly well. One of the best fitting backpacks I ve used for skiing so far. You have a breast strap and a slightly elastic, wide Velcro waist strap. The backpack snugs really well to your back and doesnt slide at all. You barely feel it when you aren't carrying more than your PBJ and R and BC safety gear.
Some more features I didnt mention: back protector, compression straps and a compartment for a water bag.
All in all: Awesome backpack, fully waterproof and best fit I ve had so far.
