Stellar Design
Love the Willis stem bag—affordable, unique fabric designs, stash pockets, attachments. The only thing I’d change is to beef up the Velcro ; use heavier-duty or one-wrap, and lose the little plastic thing. You don’t need the extra waste. Overall, the Willis stem bag is an excellent value compared to other commercially produced stem bags—way cheaper, way sexier, and more eco-friendly with PoCampo’s use of recycled materials. I’m a bikepacker as well as a town commuter, and I have this bag on both bikes. I’ve purchased two of these for myself and two for gifts. Can’t wait for new fabric designs!
5th Po Camp bag
Love the Willis Stem Bag. So convenient and goes with my e-bike and my other Po Campo bags.
Love the pattern! Perfect fit, great quality, and love the little zipper pocket. I’ll keep a cooling packet in there.
Willis Stem Bag
Keeps my drink cold for several hours.
Great bag!
Fabric quality and print are excellent. Strong stitching, secure mount. Pocket on front could be larger, for today’s oversized phone. Zipper pocket on bottom could use a widget for security and ease of use.
