This one has a significantly higher warmth to weight ratio. 900 fill to 800 on the Patagonia.

You would not need them. The Kahtoola Microspikes would do the job better.

Check out The North Face Blue Ridge Paclite which also has core vents, which would enhance breathablity. Also, the articulated sleeves on this jacket would not make significant differences, if any as they are both extremely light. Some Arc'teryx jackets are also very good choices.

Some Gore Tex Pro Shell jackets are both extremely waterproof and breathable, as well as being durable.

This will be a lot better, as it has both a higher waterproof and breathability rating. It has a 28K Waterproof rating, and about a 20K Breathability rating. You can find this at http://www.sierratradingpost.com/lp2/waterproof-guide/

In addition to eVent and Pro Shell, Dryqelite is also highly waterproof and breathable.

Gore-Tex Pro Shell and Dryqelite are more breathable than event.

Only one.

It does not say, however it should be in the 20K range for both, considering the price for such thin insulation.

The Solo is sold as one, however this one is sold in pairs.

So the movement is fairly unrestrictive?

I agree, the Salewa has better edging abilty, obviously because it is lighter and possibly less stiff as the FSN 95 is quite stiff.

No, it might stand a light drizzle, but you should get a rain cover. The Angstrom 30 has an included one and performs well.

You can attach it by pulling out the plastic piece from the inside through the hydration sleeve hole and click the rain cover's draw-string into the piece

I have the Angstrom 30, and it has a stowable waist-belt, not a removable one.

1525 cubic inches or 25 liters.

Gore-Tex pro Shell is more breathable than eVent.

It has 15.5 inch long underarm zips

So the Blue Ridge is more breathable?

Your LT may be more breathable, but this might be more comfortable because of the stretch nylon.

But the SL has no ventilation system and the more burly fabric in the SL is probably less breathable, so I'd rather go with the Blue Ridge as I am in a warmer, more humid climate. They both have a warranty.

Backcountry is an authorized dealer. Check the site.

The equivalent is 14,420.85 mmh2o. The formula is psi*576.834 equals mmh2o.

No.

I would say yes, however eVent and Gore's new Active shell are quite breathable.

The water-proof zippers are not compatible.

The venture has pit zips, is lighter and has no mesh lining, however has dry touch technology. The Resolve has a stowable hood, which the Venture does not have.

25 psi (lbs per square inch) or about 14,000 mmh2o, which is about half of most Gore-tex jackets.

Comparing this to the sl, they are almost equal, though the sl might be more preferred. The North Face Face's Blue Ridge Paclite probably would be a little better than the sl, because it has core-vents, which the sl does not have and water-PROOF pu coated zippers, whereas the sl has water-RESISTANT zippers.

The method used to measure waterproofness is mmh2o. This measures the amount of h2o (water)in mm stacked on the material, until it leaks. Those psi ratings can be converted to mmh2o by multiplying them by 576.384 (You can find this at http://www.snowboardingforum.com/outerwear-accessories/7859-waterproof-breathability-confused-explained-3.html. Gore-Tex's Waterproof rating is about 28,000 mmh2o on the hydrostatic head for most of their fabrics (Paclite, Pro Shell, Performance, etc.), which is about 12,000 mm worse than the 40,000 mmh2o of the dryQ elite. You can find this at http://www.sierratradingpost.com/lp2/waterproof-guide/ even though it does not show dryqelite (I was caught between Conduit and dryqelite). Even though th e 40,000 mmh2o is extremely high, the breathability seems unusual. For a jacket, the 40K is extremely high, which may be part of the air-permeability .

Also, some of Backcountry's ratings are COMPLETELY WRONG, such as the Stoic Vaporshell, which they recently changed to 28,000 mmh2o, which is still off, when according to the official site states is 20K and the breathability, which they state is 68,000 gm/24hrs (http://www.backcountry.com/store/review/200108808/Hydrostatic-head-quot;Waterproof-Ratin.html). However 20,000 is already a lot and the more waterproof, the less breathable.

The breathability for Pro Shell is about 25,000 g/m2 24 hrs which is less than dryqelite according to bc, however is better than any type of waterproof/breathable technology, including eVent, which is 22,000. However, some companies, such as Polartec Neoshell thought that 20,000 mmh2o is too much and made theirs 10,000 mmh2o and is extremely breathable, possibly more breathable than Pro Shell and dryqelite.

With windproofness, the rating for waterproof/breathable tech is about 4-7 cfm, which is not like Gore's Windstopper fabric (which is 0 cfm), but is windproof as the mininum is 5 cfm (I've also heard that MH dryqelite is 0.5 cfm). Gore's new Active Shell is also quite breathable, possibly more than neoshell and dryqelite, however if you are not walking into a downpour, but just some light to mild rain, you might want a softshell. Also, The North Face's HyVent Alpha's waterproof rating is quite high, about 43,000 mmh2o, however the breathablity is not very good.

I've worn many Columbia "Omni Tech" Technology garments, but they don't compare to HyVent in both breathability and waterproofness.

They do not write how much it weighs, but when I weighed it, it weighed 14.4 Ounces. It does not have a double zipper.

No. If you want a jacket in a similar price range that can zip with the Denali, the Boxster would work.

According to the specifications, both the Venture and Pursuit has an equal waterproof rating of 25 psi (lbs per square inch), though I heard that they have 40 psi. The breathabilty rating is almost the same, though the Pursuit is slightly more breathable. The HyVent 2.5 Layer is more breathable and more durable as it is a waterproof membrane, not a polyutherene coating. This jacket is slightly lighter though they are both made of the same material. Both the Pursuit and the Venture have underarm vents and have adjustable hoods. The Pursuit's retail price is about $130, which is $30 more expensive than the Venture's price. One thing that the Venture has that the Pursuit does not is that in can stuff in it's own pocket. Overall, in terms of features and performance, I would chose the Pursuit, however, if you want the one with a lower price, you would want to choose the Venture.
