Choose X-Lab accessories when you want functional design and aero performance

The XLab Stealth Pocket 300 is the sleekest, low profile nutrition bag on the market.

It's bolt mounted, so your storage will not move, while a Super Slide zipper allows for quick and easy access.

It can hold up to five gels, despite its incredibly aero design.


More aerodynamic - Actually reduces drag caused by stem and headset spacers. It's the same width as a head tube (Standard size bag), therefore no increase in frontal area. The 72 degree front fits tight up against stem and it boasts a tapered aero design profile while the super smooth low skin friction exterior reduces drag.

Non sway design - The non-slip surfaces underneath and on front of the bag grip the top tube and back of stem and a direct mount into integrated top tube bolt bosses with reliable non-seizing steel screws, and sturdy plastic insert.

Easier to use - Located within easy reach while riding and a non-slip, one handed Super-Slide rubber zipper allows you to access your vitals easier.

Smart storage - Mount the Stealth Pocket 200 behind the stem on integrated top tube bolt bosses, while the silver colored interior makes it easier to see contents. Also fits longer energy bars.

Contents stay cooler - Insulated sides keep your nutrition cooler because a silver interior helps reflect heat, not absorb it.
