Description of Arc'teryx Delta SV Fleece Jacket - Men's:
Frigid temps mean nothing to a Wookiee. If you want to know what Chewbacca feels like in cold weather, zip up the Arc'teryx Men's Delta SV Fleece Jacket. Polartec Thermal Pro fleece has a high warmth-to-weight ratio, breathes well, dries quickly… and feels like fur—probably much softer than a Wookiee's at that. The full front zip has a chin guard to prevent scraping, and the gusseted underarms keep the jacket in place. Since the Delta SV Fleece Jacket includes an antimicrobial coating, you won't smell like a garbage chute if you wear it every day.
Who are these people who complain about the lack of windproofing? Don't you get it? This is supposed to be a layer UNDER a shell. It's the shell that should be providing windproofing. If they had made this jacket more windproof, then it would take away from it's breathability. Then the moisture retention would create it's own problems in freezing temperatures, and then I for one would not have bought it. This jacket is probably not fire proof either, but so what?
This is a very warm bit of fleece insulation. Don't be fooled into thinking this is a frigid weather jacket, though. As it is highly "breathable", it is the reverse of windproof. Its general use is for layering under a windproof shell when its very cold, subtracting layers when it warms some.
For wearing around the house or the office this fleece is WAY too warm! I totally roast in it. But when the temps hit 0 to -20 you're really happy to have it. You'll probably never find a warmer fleece.
It's sorta annoying that the fleece has so little windproof-ness. You can be burning up in this fleece and walk outside only freeze in like 20 seconds. I guess i'm saying this fleece is a mid-layer only!
As far as the fit it's perfect. I have a medium Gamma SV so i ordered a medium Delta SV and the fit was exactly as expected.
In terms of quality, it's a really well built item. My only compliant, albeit very minor, was/is the draw strings in the pockets were way way too long so when you tightened them they would be really long and hanging out of your pockets or you have tons of bunched up cord. This makes it difficult to get things out of your pockets.
bottom line: SUPER warm mid-layer fleece for subzero temps only.
