Very Light, Packable Spring/Summer/Autumn Rain Jacket.
Picked this beauty up for $130 at an online post summer sale and have been making good use of it with our rainy North East weather this Fall season.
PROS: Very light and packable. Great price. Short of ice climbing this jacket is ready for the rough and wet outdoors.
Great fit; like most Mammut gear this hugs my 5'8" medium build frame well. The sleeves are well cut for the size as is the torso length which provides adequate coverage without too much fabric. Also the stretchy areas around the shoulders, elbows and torso are very effective for movement. Neck coverage, which usually is absent in super light low budget shells (see PATAGONIA Super Cell), is great on the Alverstone. When it rained sideways I easily tucked my chin inside the neck and was dry and warm. The brim/hood is also great. As someone that hikes with glasses on, this passed my "keep rain spray off my lenses test" with flying colors.
With a crispy crunchy shell and great factory DWR treatment the DryTech fabric is just as Waterproof and Breathable as my $600 Alpha SV Proshell Jacket. That being said, this is my third Drytech jacket by Mammut (I briefly owned a Mammut BC Light which turned out to be the worse use of Drytech fabric-that wasn't constructed well enough for warmth and durable enough for the outdoors). The Alverstone's Drytech is very advanced to previous Drytech jackets in that it exemplifies many Alpine Ascent design principles based on keeping the active person warm and dry (see pictures).
CONS: Very slim pocket entry and small sized pockets as in forget about putting a gloved hand in there. I had trouble fitting a DVD in there when I wore it to return my Netflix. Which is unusual because Mammut usually makes all their gear with relatively large outer, and even larger inner, pockets. This jacket also has no inner pocket.
The thin shell may not be durable enough for Ice Climbing and Extreme Weather Expeditions.
That said, this would make a great 4 season Alpine shell for those who specialize in quick and light ascents. For everyone else it is a great 3 season rain jacket that looks good, feels good (worn or packed-since you won't feel the weight), and gets the job done. Ice Climbers go elsewhere.
