When you only have to carry a few things and want to travel light, the T-28’s are exactly what you need. The T-28’s will carry your beach towel, a good book, sandals, and lunch for a trip to the beach. On the way back home, put that wet bathing suit in the external mesh pocket. Have a longer trip in mind? Combine the T-28’s with the T-42’s for a great front-rear combo. Isn't life simple at times!!?? Pack fits securely on standard bike racks (sold separately).
