An athletic jersey having at least one sleeve with a shoulder panel and sleeve panel, and a back panel having first and second back panel lateral edges mated and joined to the sleeve panel of the sleeve, and a front panel having first and second front panel side edges mated and joined to the shoulder panel of the sleeve as well as a collar edge mated and joined to the shoulder panel. The jersey has side panels mated and joined between the front panel and back panel, such that the side panel comprises a beam element and an arm element extending from the beam element and having a substantially triangular shape extending from the beam element forward about the triceps of the jersey to form the sleeve in combination with the shoulder panel and sleeve panel, substantially eliminating loose fabric about the wearer's underarm.

A wetsuit is provided which comprises (a) a first central region comprising a first material and having a first thickness; and (b) a second lateral region comprising a second material and having a second thickness. The buoyancy per unit area of the first region is greater than the buoyancy per unit area of the second region.

A wetsuit (101) is provided which comprises (a) a first central region (125, 127) comprising a first material and having a first thickness; and (b) a second lateral region comprising a second material and having a second thickness. The buoyancy per unit area of the first region is greater than the buoyancy per unit area of the second region.

A method of providing a garment with low aerodynamic drag for an individual person includes providing a database containing data relating to the aerodynamic performance of a plurality of garments when worn by a plurality of persons having different adopted body shapes, determining the adopted body shape of the individual person, and entering data relating to the adopted body shape of the individual person into a computer. The database is interrogated to identify a set of aerodynamic performance data relating to garments worn by a person having a similar adopted body shape to the individual person. The computer compares the aerodynamic performance data of the garments in the identified data set, selects from the identified data set a garment having a relatively low aerodynamic drag, looks up in the database the characteristics of the selected garment, and uses at least some of the characteristics of the selected garment to provide a garment for the individual person.
