Clark is big enough to carry things you probably shouldn't, and then it carries more. Side gussets unzip to unlock extra volume for those trying to carry too much moments. Conversely, compression straps make unneeded volume vaporize. And if you do it in the dark, a huge reflective back panel, front and side reflective stripes, and double vista loops keep you seen and safe. Finished off with natural-feeling shoulder straps, an airmesh ventilated back panel, and total laptop protection, you'll almost forget you're carrying so much.
