Like Chainsmith, SILCA is driven by passion, precision and performance. This Italian Company is backed by over 100 years experience in the industry, and they pack their knowledge into every product, including the latest Seat Capsule.

As described : 

• Thermoformed shell
• 36 cu in / 600 cu cm
• Can hold two 700 x 30mm tubes / one 29 x 2.35in tube
• Boa system for securing
• Two internal dividers for CO2 cartridge, tire levers, multi-tool

The bonus for MTBers, Silca designed the Seat Capsule Premio as compatible with up/down posts. 

A seat rail guard lets the Boa closure snug the Seat Capsule Premio tight to the saddle without needing a strap around the seatpost. Without a strap on the post, the seatpost can then be lowered to its full travel.

It holds a lot, as can be seen above. Definitely a great necessity item, and an awesome present for any cyclist.
