The men's streamlined Arc'Teryx Theta SL combines 2 great waterproof, breathable Gore-Tex® textiles. This PacLite® jacket features Gore-Tex Pro Shell reinforcements in critical areas.

  • Below-hip length offers maximum coverage, and a short list of critical features keeps the Theta SL light and packable
  • 2.5-layer Gore-Tex PacLite is engineered specifically to be light, packable and more breathable than other 2- or 3-layer Gore-Tex fabrics
  • Lack of need for a separate lining allows fabric to be light and compact; combines durable wind- and waterproofness with exceptional breathability
  • Shoulder, collar and sleeve areas are reinforced with 3-layer Gore-Tex Pro Shell with an ultra-thin backer for added durability
  • Micro seam allowances increase breathability and suppleness, and save weight; all seams are sealed for complete protection
  • Lightweight Stow Hood™ with molded brim compresses to hide within the jacket's collar; it's accessible through a watertight zipper
  • Pit zippers allow easy and efficient ventilation; WaterTight™ zippers do away with bulky zipper flaps
  • Features laminated hem and waist drawcords and quick-drying chin guard
  • WaterTight front and pocket zippers; jacket has 2 hand pockets
  • Articulated elbows and No-lift gusseted underarms let jacket remain in place when arms are raised, and ensure unhindered movement
  • Trim athletic fit enhances performance

Arc'teryx Theta SL Jacket - Men'sis rated5.0out of5by4.
Rated5out of5byfromAmazing jacket.I bought this jacket on clearance as Arc'Teryx is just too expensive retail, even if they do have the best fitting stuff out there. This is my second shell I've ever owned. I bought my North Face Mountain Light 20 years ago with lawnmowing money when I was 16 and it was legendary for setting the bar for technical shells. I hope this shell lasts me the next 20 years. So far so good after 6 months. Love everything about this jacket so far. I'm 6'1" 190 so I'm thin-ish and the Large fits flawlessly. The torso is trim with no bulk but room for insulation layers. The arms are just a tad long, but that could be by design for covering gloves well.(and I have somewhat long arms I guess). This is one of the few jackets you'll find that has a stowable hood. I think it's unacceptable that jackets wouldn't have this option, even on a "SL".

Rated5out of5byfromGreat features / not for every season• Used for spring and fall canoeing and hiking, winter camping / snowshoeing, bike commuting and some roller skiing • Great waterproofing • Great detailing and product design • Very durable — has held up well amongst heavy brush, branches and going up against rough surfaces • Keeps its shape well • Overall product line seems to fit slim physique best • One of the few shells that has a stow hood feature • Hood would not accommodate a ski helmet easily, but a good size for a bike helmet and winter head gear • Material doesn't make a lot of sound when moving — this was an important factor in my search since I wanted a material that kept "quiet" when hiking, portaging and in areas where one wants to enjoy the silence • Not the most breathable shell

Rated5out of5byfromOutstanding piece of kit!The cost is on the extreme end, but once you start going through it, you see features not available on other jackets of it's weight. Seams, zipper coil, zipper pulls, construction and materials are way above all competitors. Not many jackets of this weight are fully water PROOF, this one is. Great for spring and summer outdoor and urban hiking, camping or rainy day casual wear.

Rated5out of5byfromGreat JacketGreat jacket, that seems as bullet-proof as it is packable. The zippers clinch a little, as do most water tight zippers. Very light for the durability.
