Arcteryx Alpha SV vs Beta SV
|
I live in an environment of pervasive rain. Clouds so low we walk in them, amidst old-growth forest. Most hard shells that claim to be waterproof are proven deceitful, or at least eventually impotent, in this saturating clime. As such, I am looking for a heavy duty shell that might withstand the rain's kind onslaught. I am interested in the Alpha SV due to its burlier fabric, but am wondering if any have thoughts on the Beta vs the Alpha? Or perhaps I should be looking in another direction altogether? I've done Guy Cotton and Grundens before, and am hopeful to find something as impervious to water, though that might breath just a little. Any thoughts will be met with appreciation. |

The Alpha SV and Beta SV are going to be similar jackets besides the fact that the Alpha has a longer cut and a heavier face fabric. Both jackets will perform well, but the heavier the face fabric the less the jackets will breathe. If breathability isn’t your number one concern I’d go with the Alpha SV. |

My experience is that any of the LT series of Arcteryx coats do not withstand the level or saturating rain and sea spray I am frequently in. Looking for something I can wear in all day rain that won't let water in. Was hoping the burlier fabric would equate to more waterproof--you're saying this isn't the case? Further, in my experience, no hard shell rain coats really breath all that well. If I'm hiking I need pit zips to really dump heat, even though I know that pit zips actually make a jacket less breathable. I have just never found a hard shell that is waterproof and breathes well. And I am prioritizing waterproofness now. Though not to the point of rubber rain gear. |

Check out the Columbia OutDry jackets. I've only had mine briefly, but it seems pretty waterproof. They don't use a DWR coating because the waterproof membrane is on the outside. |

How does Beta SL Hybrid compare to either of these models ? |

Its a great jacket for majority of activities and is going to be a good jacket if you are just using it for hiking, walking around town or other activities. It has Gore-tex Paclite instead of Gore-tex pro which means it won't breathe as well, but it does have pit zips to dump heat. It does have heavier fabric reinforcement in high abrasion areas as well. |

Billy Pilgrim wrote: Yessir. The face fabric protects the membrane from wetting out and abrasion. Although once the face fabric is wet the breathability goes to hell. This is when a hardshell will start to feel wet due to sweat |

Billy Pilgrim wrote: On Gore-tex Pro shells there are 3 layers. The face fabric (nylon), the gore-tex membrane, and a nylon rip stop. The face fabric is basically just there for abrasion and tear resistance. The face fabric will not be waterproof, but it will be water resistant and will be coated with DWR which is what makes water bead on the surface. The gore membrane is going to be what is waterproof and what is there to prevent the jacket from fully wetting out. If you want to see what the gore membrane looks like then search the Arc'teryx Norvan SL. The nylon ripstop is there for comfort (kinda, it is more comfortable than paclite), but is also there so that if the shell gets ripped, lets say by an ice axe then the rip stop in theory will stop it before it gets to your skin. As I said earlier, the price difference between an Alpha SV and Beta SV is essentially the density of the nylon face fabric. The heavier the material the more bomb proof the jacket will be in terms of abrasion resistance and the ability to not rip.In theory an Alpha FL, Beta LT or Beta AR should perform just as well as these jackets as far as "waterproofness" goes. Another thing to note is the care routine of a Gore-tex shell. Make sure you use a performance wash on it and reapply DWR every time you wash it (before you dry it). Based on the environment you described in your original post I would probably wash and reapply DWR about every 1-2 months. |

I videotaped myself in Iceland wearing a Zeta LT jacket while it’s storming. The jacket was rather impressive considering the price point and the quality. I guess if the zeta LT can handle the stormy Iceland in May, it can handle your misty environment. Hope that helps. If you need my video as a proof, leave your email below and I’ll send it to you. |

You may want to review Gore's Shakedry technology, "a new 'permanently beading' waterproof/breathable membrane technology from Gore-Tex that eliminated the need for a DWR-treated face fabric and that purportedly wouldn’t wet-out. If true, that’d be a big deal, because it would solve one source of failure of modern rain shells." |

mpech wrote: This. Waterproof and breathable (in any meaningful way) is a unicorn. You can stay dry for a while if you are basically sedentary. But eventually your own latent heat will escape into the inner jacket, hit the cool waterproof layer and condense on the inside. Then you will think the jacket is leaking. There is no realistic way around this fact. The same thing happens on non waterproof layers, but to a lesser extent. A Houdini will wet out from the inside noticeably if it is cool and you are working hard because while it breathes much better than a gortex jacket it still doesn't actually breath well at all. Same principle as condensate forming on a cold surface like a window on cold day or a glass of cold water. |

I’m a sailor do I know wet. Look at GIL. Gil 0S1, 0S2 and FG2. Or hell go for the 0S3 and be done with it. Great jackets. The “yes I just stepped off the boat from my round the world bid” look just adds to appeal. |
