Pros & Cons

Reasons to buy:

User Reviews

  • Waist adjustment strap and hood-adjustment cord at the back of the hood allow for adjustability.
  • Very lightweight – only 6.4 ounces!
  • Waterproof due to Pertex Shield+ 2.5L 30D ripstop nylon and sealed seams.
  • Zippered pocket on chest and velcro pocket inside the left-hand side.
  • Internal pocket features small loop for attaching keys.
  • Easy to store into a pack.
  • Able to stuff into own pocket for compressibility.
  • Waterproof zippers.

Expert Reviews

  • Features the water-resistance of a rain jacket, combined with the weight of a wind jacket.
  • Two reflective-patches increase safety when exercising outside.
  • The elastic cinches on the hood extend up to the temple and not across the brow.
  • Chest pocket features as a “stuff pouch” with a clip-in loop for a harness.

Reasons NOT to buy:

User Reviews

  • The material can feel clammy during perspiration.
  • Elastic wrist openings, but no wrist-adjustment straps, leading to some air escaping or rain entering.
  • Not especially breathable.
  • Will need to size-up if want to wear layers underneath and not be too snug.
  • No pit zips.
  • Some reports of tight shoulders and sleeves when purchasing true to size.
  • Jacket doesn’t reach very long in the back.

Expert Reviews

  • Loose wrist cuffs can allow heat to escape.
  • Does not have any specific ventilation features.
  • Does not have any comfort features, such as a micro-fleece chin strap.
  • Runs slightly snug, and is a slim-fitting jacket, so should be aware when purchasing.
  • Length is a bit short for tall people and can ride up when raising arms.


The Outdoor Research Helium II Jacket for men is a great option for those who want a very lightweight rain jacket. While not super breathable, the feather weight and stripped down feature-set are ideal for fast and light outdoor activities.
