What Our Gearhead(R) Experts Are Saying:"I have been commuting on the Shield Attache Inlock 16in through some genuinely miserable spring weather, and my laptop has stayed completely dry every time. The InLock attachment clicks on and off fast enough that I barely break stride between the bike and the office door."Rain on the way to work used to mean a tough choice between the bike and the bag. The Thule Shield Attache Inlock 16in removes that tradeoff entirely. IPX4 waterproof protection, welded seams, and a sealed zipper mean your laptop and everything else inside stays dry regardless of what the morning commute brings. Click it onto your InLock panel, ride in, pull the webbing tab, and walk through the door looking like you planned it that way all along.
