This is the second travel bag I've owned, the other bag was by EVOC. And I much prefer the Dakine. Size is a tad smaller, and the internal layout and storage is slightly better in its design. The Dakine bag also uses recycled polyester! Dakine just makes some of the best travel bags, I have and use there ski sleeves and boot pack as well. Dakine is doing more Bluesign and recycled fabrics throughout their product line, and so I'll keep paying attention to what they're making.
Have used this pack about 10 to 15 times, and I love it! It holds plenty of water for a ride up to about three hours long. Anything more than that and youï¿½ll probably need an extra bottle on your bike. The pack stays in place well and the extra storage is very handy. The only thing that kept it a four-star instead of five stars is the magnet holding the drink nozzle to the pack doesnï¿½t always hold as strong as I would like.
From fit to material, these are my favorite riding shorts. The zippered pockets are key. Other Dakine shorts I have donï¿½t have the zippered pockets making it more challenging going when needing to carry keys, phone, etc. I normally wear size Large (33ï¿½ waist and slim overall) but I opted to size down due to my experience with previous Dakine shorts. The medium fits well, doesnï¿½t require tightening or a belt although Iï¿½m at the max in the waist.
Well-designed bag for small loads such as tools, a tube, and other incidentals. It fits rather flat, so will work fine under a jersey, but the flat design does limit it's carrying capacity. A stretch pouch outside the main compartment will fit a road tube, no problem, though a MTB tube is probably too large. Hipsters, if you want to carry a can of PBR with you, look elswhere. Ditto CCW types, your compact 9mm is too big for this bag.
Despite the smaller size, I find this bag very useful for many rides, to carry my phone, wallet, and tool kit, leaving jersey pockets for food, and a wind shell. Also good for summer use, when it's great to have nothing in your jersey, so completely unzipping for a Flapper is easy.
