And don't believe them when they say that these bags won't stay standing. If you pack it right, it stands up just find on its end (aka heavy stuff on the bottom-duh). Got it in pink plaid. Many, many zippy mesh pockets on the inside. Rather heavy duty outer fabric. Heavy duty clips, places on the zippers for locks and flush/flat luggage tag.
I got it b/c I loved the matching snowboard bag. Both awesome. The 4000 is plenty big also.
