A jacket that's in the same league as Arc'Teryx (sort of)

As a replacement to my Arc'Teryx Theta AR jacket, the Beryllium seems capable to holding its own. What I cannot understand is why the main zipper is not water tight like all the others found on the jacket? If it was I definitely would have given it a 5 star rating. The flap with it's velcro tabs does protect the zipper, but, you would think that a water tight zipper would have been a better option. On a positive note, the Gore Tex Pro shell fabric seems less restrictive than the Theta. And after a good old fashion downpour, I was definitely warm and dry. Plenty of room of layering and the 2 front chest pockets are big enough for a Garmin 60CSX and the zipper tabs are really nice compared to the "string loops" found on the Theta.

So would it be right to compare this jacket to the Theta AR? Compared to the Beta AR, is the only difference really the back length? I'm really only asking about sizing.

"The reason that we don't use the waterproof zipper as the main zip on this jacket is because we have found that they don't slide/zip all that well..." Especially when you're in an ice fall and ice builds up on those rubber zippers.

The reason that we don't use the waterproof zipper as the main zip on this jacket is because we have found that they don't slide/zip all that well and they are not waterproof anyway! They sure look good though and that is why we use them on some of our jackets and in secondary pockets on the jacket. As for the large tooth zipper on the Beryllium? It's the most durable zipper (avoid blowouts) we could find and it zips well! I am glad you like your jacket!!
