Spada 911 Trousers are a waterproof and windproof summer trouser, which are fantastic value at this budget price.  They are not an overtrouser (unless you're incredibly skinny and wearing close fitting leggings) - so if that's what you're after check out the separate listings for waterproof overs.  They are unlined and unarmoured, just a good basic waterproof trouser to keep the weather off.  Spada 911 trousers feature:

• 100% waterproof & windproof
• Nylon shell
• Unlined
• Elasticated waist
• Zip & Velcro leg closure

Sizes Available: S - M - L - XL - XXL
