I just checked this bivy weight on the MSR website, it is 9oz (minimum) and 10oz packed. Not 7oz.

Took it to a fully testing mountaineering trip - It performed brilliantly.
On the valley, this super lightweight jacket kept me dry through hours of pouring rain. Waterproof pitzips take care of the breathability. Crossing a creek got me into chest deep water - this shell dries as quick as you'd imagine. Above the snow line, the jacket's hood worked so well with the helmet and shields you from the wind nicely. A cautionary note: Although well constructed, it is an uber-light shell - trees and shrubs will shred this shell. It's more on the fragile side, the price you pay for going light. I simply love this shell.

As good as is expensive. I took this Jacket for glacier travel and ice climbing in New Zealand. After full day
walking and climbing on the pouring rain I was impressed with this
highly waterproof softshell. The Pitzips and the helmet compatible
hood work seamlessly. This jacket keeps you happy while you swinging your axes and wear your harness. Colours and looks however, differ a lot from the picture - The Arc'teryx guys "retouch" these photos excessively. I have not tested it in cold weather though.

Downsides with this pack: Sizes are quite weird - I'm just 5'7" and the S/M is way too SMALL for me! the M/L fits me perfect (Bad news for people taller than me = Most people). The pack is (understandably) Zero water resistant so as you use a dry-sack liner, the side access (for which the zipper SHOULD have been WP) becomes useless. The upside is basically everything else: It is well designed, lightweight and comfortable (considering it's a technical rather than a backpacker's pack). The ice-axe loops/pockets system is just brilliant. The helmet holder is brilliant. The crampons pouch is brilliant - you know the adjective for this pack...

This Bivy sack does what it's meant to, nothing more. It is amazingly light and is designed to keep you warm and dry while sleeping mostly ABOVE the snow line. i.e. when it is cold and snowy and rain is not your biggest concern. The biggest advantage is its highly breathable fabric (my experience, I see some controversy here), which is priceless as I use a down sleeping bag. Its disadvantage are the almost "transparent to water" seams, hence I strongly recommend sealing the seams for true water resistant (NOT waterproofness) If your are after water proof, Gore-Tex, and the like, this is not your sack.

The spork is beautiful, love it.
The pot is pretty as well, lightweight, well built and the best price for a titanium pot. Its design however, could be easily improved: It is too narrow and tall - its proportions make the pot not so heat-efficient and prone to burn the food at bottom while cooking the rest. The lid could fit snugger to make draining easy. Bottom line: I like it and I'm happy to have it but you'll struggle if it is your cooking pot. Great for boiling water and use it as a mug/bowl. It's clearly behind the (overly priced) MSR Titan Titanium Kettle.
