The only sleevecase manufacturer you need to consider is
WaterField Designs. They make the best sleeves available, here in the USA, and offer a no-hassle lifetime warranty on everything they sell. More, their pre and post-sales support is unmatched: the founder of the company, Gary Waterfield, responds to any question or concern you may have at <
heygary@sfbags.com>. I've had the pleasure of exchanging e-mail with him on a few occasions, and he's a first-class individual who sells top-notch products.
For the X301, you'll want the size 13-1 sleevecase:
X301. (
here is the sizing page itself).
You have a few options on the sleeve, but you're stuck with black. I'd imagine if you asked, Mr. Waterfield might custom make one in a different color, but you'd have to pay an additional fee.
Vertical or Horizontal sleeve orientation. Usage applications described
here.
Whether or not to add
a flap to the sleeve. Because I carry my WaterField sleeves in a Timbuk 2 bag, I always add the flap (+15.00). The velcro that secures the flap is industrial strength. I've opened the sleeve in a student common area and have had people turn and look to see what the noise was.
Whether or not to add a shoulder strap. Here, there are additional options (
picture):
- add d-rings only (+$5.00). I always choose this option so that I can connect whatever strap I want. The d-rings are metal, not plastic, and are securely sewn to the sleeve. I've tried to force them loose and haven't been able to do so.
Add a strap (+$12.00). This is the normal strap. I've no experience with it.
Add a suspension strap (+$18.00). This is the one I have, and it has a textured shoulder pad area that prevents slipping--it does a good job at this, though the shoulder pad area isn't quite large enough for me.
Whether or not to add
a piggyback, which is a well-made zippered storage pouch that attaches to the d-rings. So, if you order the piggyback--it holds a charger, USB devices, and the like--you'll need the d-rings, too.
As linked above, WaterField also sells a number of bags and offers a bag + sleevecase combination, depending on the style of bag you might want. You can find out more about this offer, which would save you a small amount over purchasing the bag and sleeve separately,
here.
Do give WaterField serious consideration (and try one of their sleeves for your X301). If you're not thrilled, they'll take it back, no questions asked. Waterfield truly is among the best available product. You can read some testimonials from customers

Hope this helps! If you've questions, I'm happy to talk about their sleeves. For reference, they have a
FAQ, too.
