Rains Size Guide
Rains is a Danish brand specialising in minimal, design-led all-weather outerwear founded in 2012. The brand's sizing philosophy centres on a deliberately loose, generous fit designed to accommodate layering under rain jackets and cater to cycling culture. Rains offers five core sizes (XS, S, M, L, XL) across unisex rainwear and women's-specific collections, with separate sizing for trousers. All pieces prioritise comfort and functionality whilst maintaining Scandinavian simplicity. If you typically wear a medium in standard brands, you may find Rains sizing runs one size larger, so consider sizing down if you prefer a more fitted silhouette or are between sizes.
How to Measure
- Chest: Measure around the fullest part of your chest with the tape parallel to the ground.
- Waist: Measure around your natural waistline, keeping the tape comfortably loose.
- Hips: Measure around the fullest part of your hips and seat.
- Arm length: Measure from the centre back of your neck down to your wrist with your arm relaxed at your side.
- Inseam (trousers): Measure from your crotch to your ankle bone, or try on a pair of trousers that fit well and measure the inseam tag.
Tip: Rains garments are designed to be worn with warm clothing underneath. When selecting your size, choose the largest measurement range that accommodates your body comfortably.

Product-Specific Guidance
Rain Jackets
Rains rain jackets are cut in a relaxed, unisex fit with extra room for layering thermal and winter wear underneath. The fit is intentionally generous to allow free movement when cycling or walking. If you prefer a closer, more tailored silhouette, go down one size. Refer to the product page model heights and sizing information for reference fits.
Raincoats & Outerwear
Women's raincoats have a more fitted profile than unisex pieces. A unisex raincoat in size M corresponds to approximately a women's size L, so account for this when choosing between collections. The looser fit of unisex styles suits those who wear thermal layers or prefer maximum mobility.
Rain Trousers & Shorts
Measure around the fullest part of your hips and cross-reference with the inseam. Rains offers consistent inseam lengths within most size brackets (except XL, which runs slightly longer). Inseam length is consistent across sizes S–L, so prioritise hip measurement when selecting your size.
Layering & Fit Consideration
All Rains pieces are engineered for layering. Choose your size based on your largest body measurement to ensure comfortable fit when worn over jumpers, thermal tops, and insulating layers. The brand's philosophy centres on practical, weather-resistant apparel that does not restrict movement or ventilation.
Sizing Tips
- Generous fit by design: Rains pieces run larger than typical sizing. If you are between sizes or prefer a snug fit, size down one size.
- Layering allowance: All measurements account for wearing warm clothing underneath. Measure your body, not your intended layers, then select the size that matches your largest measurement.
- Women vs. unisex: Women's outerwear is more tailored. Unisex sizing is significantly roomier, roughly one full size larger than women's in the same number. Choose women's if you prefer a shaped fit and unisex for a relaxed, oversized silhouette.
- Check product photos and styling notes: Each product page includes the model's height and the size they are wearing. Use this visual reference to gauge how the piece will hang on your frame.
- Inseam consistency: Rains trousers in sizes S, M, and L share an identical inseam range (79–81 cm). Select size primarily by hip measurement rather than length, or measure your current well-fitting trousers' inseam for accuracy.
- Order two sizes if unsure: Rains recommends purchasing multiple sizes if you are uncertain. Returns are free and easy, making it simple to find your ideal fit without risk.
- Cycling-friendly design: If you cycle regularly or prefer garments with extra ease, choose your usual size. If you prefer snug tailoring, size down. The roomy cut supports freedom of movement and air circulation.
