Close-fitting stretch waterproof pants with unrivalled mobility and comfort.

Soft, stretchy & crinkle-free like softshell
Fully waterproof and breathable like a hardshell
Light and highly packable with small stuff sack
The ideal protection for varying conditions

Fully waterproof, highly breathable, stretchy and comfortable, Rab Kinetic Alpine Pants could change the way you think about outdoor wear.

Made using Rab's Proflex fabric, they're soft and flexible like softshell, with the protection and durability of a hardshell - the inner quickly wicks away any moisture, while the outer protects you from the elements.

Ceramic print overlays at high wear areas increase durability and reduce the risk of snagging without hindering flexibility. The low profile waist adjustment, zipped expanding ankle closure and knee articulation all ensure high functionality for the mountains.

  • Proflex™ fabric with tough nylon face
  • Ceramic reinforcement on seat, knees and instep
  • High gauge knit wicking lining
  • Low profile drawcord waist adjustment
  • YKK® reversed fly opening
  • 2 YKK® zipped handwarmer pockets
  • YKK® zipped expanding ankle closure
  • Knee articulation
  • Webbing loops at hem for under-boot cords
  • Slim fit

Rab's Proflex fabric uses a waterproof PU membrane sandwiched between two high gauge knitted layers. The outer layer is very thin, soft to the touch, and super-stretchy; the inner layer maximises moisture movement to keep you dry when on the move.

WAIST: Measure around the smallest part of your waist (natural waistline).

HIPS: Stand with your heels together and measure around the fullest part.

INSIDE LEG: Measure from the top of your inner leg, along the inside seam to the bottom of your leg.

Great waterproof trouser

Had these for about a year and honestly really rate them, I wore them through summer in Ireland which was basically non-stop rain. Nice snug fitting, so no crisp bag feeling or swish swish sounds.

Tear first use

Sat down for food on a rocky area and once finished the hike noticed a hole in the panel, not impressed with RAB the dexterity was very poor.
Waterproofing was very good in the snow and rain.

My choice for life

I will not be buying a different waterproof trouser for use in the UK. These are thin enough to stay cool when active & fully waterproof/flexible. Add under layers if needed

Used for hiking & cycling

Bought these early March and wore them in the subsequent March storms.
Extremely light & comfortable and can verify that they are indeed waterproof and windproof in horizontal rain. They are also very fast drying after a good soaking. Fit is true - I'm a 34 and they are a perfect fit. Initial impression is that they will be ideal for spring, summer & autumn, but suspect they may prove a bit chilly if the temperature drops to zero or below due to the thin fabric. Cannot comment on the durability as yet, but they seem to be a quality product.
