The ideal riding jeans should be comfortable and fit well, both on and off the bike. They need to look good, yet be sturdy enough to withstand whatever wear and tear you inflict upon them. Above all, they need to protect you with high tear and abrasion resistance, and protect you with its armour, yet remain comfortable. Therefore, it is important to look after your favourite pair of riding jeans the correct way.
Remove armour before washing & turn jeans inside out.
Use a mild detergent, avoid using fabric softeners.
