Choose the Sonora sleeve format by the coverage and cuff routine you want. Both classic shirts list the same 48% polyester, 48% nylon and 4% spandex blend, underarm mesh and snap closures. The meaningful difference is not a claim that one version is technically superior.
The long sleeve has a fit problem the short sleeve cannot reproduce
Brad finds the long-sleeve version restrictive at the shoulders; Leonard sized up and ended with more sleeve length than he wanted. The short-sleeve version removes that cuff interface, but its owners also report snug torso fits. It is an option when you do not need forearm coverage, not a proven wider shirt.
| Your preference | Try first | Acceptance check |
|---|---|---|
| Keep forearms covered without another layer | Long sleeve | Reach with cuffs closed and no pulling at the shoulders. |
| Avoid extra cuffs during warm-day work | Short sleeve | Front stays comfortable while sitting and reaching. |
| Use one shirt for work and outdoor stops | Either | Inspect the exact underarm-panel contrast. |
Several short-sleeve owners also own long-sleeve versions, but their positive fit impressions do not erase other buyers’ complaints. Both fabrics carry a manufacturer UPF claim; that label does not give uncovered skin the same coverage as a sleeve.
