Seraks GTX WS Jacket

  • Familiarity:I've put it through the wringer
  • Fit:True to size

Comfortable soft-shell jacket that really breaks the wind. Despite the name GTX, the jacket is a wind stopper, not full waterproof Gore-Tex material so while it holds up in high wind, snow and light rain well, it is not a suitable rain layer (check out the Patroul GTX instead). The pockets are HUGE. The hood fits over a helmet. The waistband and wrist cuffs cinch tight to keep wind out and the inside material is soft if you switch to a t-shirt after a workout. Despite the excellent wind proofing, the jacket breathes well and is suitable for higher output activities in the cold like skiing uphill and ice-climbing.

Can't say enough about this piece. should put this on the G.O.A.T list as it does what I've always wanted a jacket to do while ski touring.... Block wind, keep me warm, and breath well. I've always been a fan of softshells for their breathability - just not the bulk. This ways just a hair more than most high end shells. And breaths... Athletic fit is great too for active use and no chatter in the wind or on descents. Easily had 50 days in it so far this season and very little signs of wear.

Great for cold weather aerobics

Got this jacket not to long ago and now use it as my winter outer layer piece for trail running, ski touring, and climbing. Breathable enough to keep you cool during your climbs and thick enough to keep the wind from making your under layers useless. Im a big fan of this jacket.

The sizing chart for Dynafit is way different...

The sizing chart for Dynafit is way different than most manufacturers. The "small" column shows height as 5'-9'' to 5'-10" and waist as 33" to 34". Would a "small" jacket fit me . I am 5'-7" and my waist 31".

This is listed as GTX .. but it is described as Windstopper, not Gor-Tex. Which one is it?

GoreTex is the marquee product of a W.L. Gore and Associates. It was invented in the 1970s and to this day remains one of the best waterproof/breathable fabrics available in outdoor clothing. Windstopper is also made by Gore but is instead their windblocking/breathable fabric. Gore pretty well keeps these fabric tachnologies separate allowing companies to use GoreTex primarily on hardshell clothing, and Windstopper on softshell. Windstopper fabrics will only be water resistant rather than waterproof, but they will also breathe and wick moisture away better than a GoreTex.
