Sierra Designs Nanolite Jackets

There is a review of them, at least an initial run on this site. Seemed to say they weren’t quite perfect at least yet.

The nano material is definitely not the same as “nano” for the Bozeman stuff.

Played with one in REI too and they are light!

Covered here last year at the OR show:

Favorably compared with the (discontinued?) Patagonia Spectre…wonder how this new SD jacket would compare to the current Patagonia Houdini Full Zip weighing 4oz. …

This site really needs a better search function; this one shows up easily:

This evades the search function entirely:

Ditto for this:

“The Sierra Designs NanoLite Jacket is now “fixed” (although “fixed” wasn’t the exact term used by Sierra Designs…something about “upgraded”). They now (after the third iteration) claim that the fabric is finally waterproof, and they seam-taped the pockets, a big oversight on the ’06 production runs.”
*****
Based on all that (and a September Backpacker magazine review that seemed to give it just barely passing marks as emergency-only raingear), I decided to go with the TNF Diad instead — weight penalty is fairly trivial, quite a few useful features, acceptable breathability & venting, sufficiently waterproof, and can be bought from EMS for only $75. (Call up a store and they can search other stores for remaining inventory.)
