MU StarAir Rush Shorts vs StarAir Train Shorts 4": Fit Compared

Quick answer

Choose the MU StarAir Rush Shorts if you want a midnight colorway and sizes XS through XL; choose the MU StarAir Train Shorts 4" if you prefer classic black, a 4-inch inseam, and a wider S–XXL size range.

Color and size range decide more than you think

The Rush Shorts come in Midnight, a dark color that hides sweat and pairs with most tops. The Train Shorts 4" come in Black, the most versatile base for any yoga wardrobe. Neither is objectively better—pick the one that matches what you already wear.

Size availability is the bigger practical difference. The Rush Shorts cover XS, M, L, and XL—note that S is missing. The Train Shorts 4" run from S through XXL, so they accommodate smaller and larger frames more easily. If you normally wear a small, the Train Shorts are the safer bet.

The 4-inch inseam trade-off

The Train Shorts 4" list a 4-inch inseam, which gives a streamlined, short cut that stays out of the way in poses and hot sessions. The Rush Shorts catalog doesn't state an inseam, so you can't compare length directly from the specs—if length is critical, the Train Shorts give you a known number to work with.

A shorter inseam means more leg freedom but less coverage. For inversions or wide-legged poses, some yogis prefer a longer short; others find the 4-inch cut ideal for mobility. The Rush Shorts' unlisted inseam makes them a bit of a gamble if you're particular about length.

Lined vs unlined: what the specs don't tell you

Neither product record states whether these shorts are lined or unlined. That's a real limitation for anyone who cares about built-in support. If lining matters to you, check the product page or contact the store before ordering. Don't assume either way.

Both shorts are priced identically at USD 24.57 (compared to USD 39.00), so price isn't a deciding factor. Your choice comes down to color, size availability, and whether the known 4-inch inseam on the Train Shorts suits you better than the Rush Shorts' unspecified length.

Trade-offs to weigh before you buy

• Color flexibility: The Rush Shorts' Midnight is sleek and dark; the Train Shorts' Black is the most neutral base. Choose Midnight if you want a slightly different look, Black if you want maximum pairing ease.
• Size availability: Rush Shorts skip size S and top out at XL; Train Shorts 4" cover S through XXL. If you're a small or need XXL, the Train Shorts are the only option here. Check the size chart before ordering—Rush Shorts have no small.
• Inseam certainty: Train Shorts list a 4-inch inseam; Rush Shorts don't state one. If you need a known short length, go with the Train Shorts. If you're flexible on length, the Rush Shorts are still a solid pick.
• Lining status: Neither listing confirms lined or unlined construction. If built-in support is a must, verify with the store before purchasing either pair. Don't assume lining—confirm it directly.
