What Makes a Heavy Duty Rain Suit Perfect for Autumn Storms

Autumn storms demand gear that can handle prolonged exposure to driving rain and unpredictable weather patterns. The right features separate heavy-duty rain suits from basic rainwear.

Waterproof Rating and Breathability Standards

Look for rain suits with a minimum 10,000mm waterproof rating to handle autumn’s heavy downpours effectively.

Comfort and Mobility in Wet Conditions

Articulated joints and gusseted crotches allow full range of motion when climbing ladders or working in awkward positions during storm preparation.

Test arm mobility by reaching overhead and bending at the waist while wearing the suit. Your sleeves shouldn’t pull tight or expose your wrists when you’re working on storm cleanup tasks.

Maintenance and Care Requirements

Wash your rain suit after every 10-15 uses or whenever it’s exposed to dirt and debris. Use technical fabric detergent and avoid fabric softener, which breaks down waterproof coatings.

Store the suit completely dry to prevent mold and mildew. Hang it in a well-ventilated area and let it air dry for 24 hours before folding or packing away.

Seasonal Storage Tips

Clean and thoroughly dry your suit before long-term storage to prevent fabric degradation. Fold loosely in a breathable storage bag rather than cramming it into tight spaces.

Check zippers and seams annually before storm season begins. Apply zipper lubricant and patch any small holes with seam sealer to maintain waterproof integrity throughout the season.
