Ultralight Packable Rain Jacket & Pants Set
DETAILS
Keep lightweight weather coverage within easy reach with this ultralight two-piece rain suit. A hooded full-zip jacket and separate pull-on pants provide head-to-leg coverage in a streamlined format that's practical to carry for changing conditions outdoors.
- Two-piece coverage: Separate jacket and full-length pants provide broader protection from wet weather than a jacket alone.
- Ultralight design: Lightweight construction keeps the set practical for carrying as backup rainwear on hikes, rides and outdoor trips.
- Packable format: The compact design makes it easy to stash with your outdoor gear and have extra weather coverage ready when needed.
- Adjustable hood: Hood adjustment hardware helps you fine-tune coverage around the head when conditions change.
- Practical closures: Elasticated cuffs and a pull-on elastic waist create simple, comfortable coverage that's quick to put on.
- Zippered storage: Two jacket pockets provide secure space for small essentials while you're on the move.
Best For: Hiking, outdoor walking and wet-weather cycling when lightweight, packable upper- and lower-body coverage is the priority.

Adult Footwear Size Guide
Our adult footwear is listed in US sizing. Sizes are displayed as M for US men and W for US women. When two sizes are shown together, such as M 6 / W 7.5, they refer to the same selectable size.
How to Measure Your Foot
- Use a sheet of paper: Place it on a hard floor with one edge against a wall.
- Stand against the wall: Place your heel lightly against the wall with your full weight on your foot.
- Mark your longest toe: Mark the paper at the tip of your longest toe.
- Measure heel to toe: Measure from the edge of the paper to your mark in inches or centimetres.
- Measure both feet: Use the longer measurement if your feet differ.
- Wear your usual sports socks: Measure with the type of socks you plan to wear with the footwear.
- Measure later in the day: Feet can become slightly fuller throughout the day.
Important: Use your actual heel-to-toe measurement. Do not add extra length before checking the chart.

Choosing the Right Adult Footwear Size
- Between measurements: Choose the larger available size in the chart.
- Wider feet: If you regularly wear wide-fit footwear and the style has no width option, consider choosing the larger size.
- Performance footwear: Cycling shoes, cleats and other fitted sports footwear may feel snugger than casual shoes.
- Sports socks: Consider the thickness of the socks you plan to wear.
- Sandals: Your heel and toes should sit neatly within the sole without overhanging.
