Kitting a boy out for an Australian summer

Buying boys togs in Australia usually starts with a specific job to do: a new school swimming term, a club nipper season, a beach holiday, or simply replacing a pair that no longer fits a fast-growing kid. Each of those jobs points to a slightly different garment, which is why "boys togs" is less one product than a small family of them — board shorts, jammers, briefs, and rash tops, each with its own sizing logic and best use. Get the match right and the togs do their job all season; get it wrong and you are back at the shop in a fortnight.

In Australia, "togs" is the Queensland word for swimwear — elsewhere a boy might wear "bathers" or "swimmers", as the guide to togs vs bathers vs cossie sets out. Whatever the local term, the buying decisions are the same across the country, and they come down to style, sizing and sun protection. This guide works through all three.

The main styles, and what each is for

Boys' swimwear splits into a few clear categories, and choosing the right one is mostly about the activity:

StyleBest forNotes
Board shortsBeach, casual, holidaysKnee-length or just above; loose, quick-dry
JammersTraining, swim meets, lessonsKnee-length compression; minimal drag
Briefs / trunksRacing, competitive swimmingSnug, streamlined
Rash top / sunsuitLong sun exposure, younger kidsAdds UPF coverage over shoulders and torso

Board shorts are the all-rounder for the beach and the pool party — loose, quick-drying, and worn just above or at the knee. Jammers are the workhorse for lessons and training: knee-length compression shorts designed for minimal drag, durable enough for daily chlorine. Briefs and trunks are the racing option for competitive swimmers who want the most streamlined fit. For younger boys, or any boy spending hours in the sun, a rash top over the togs is the single most valuable addition — coverage matters more than style when the UV index is high.

Sizing boys togs by age

Australian boys' swimwear follows the same two-stage sizing as most kids' clothing. For younger children it is sized by age; for older boys it shifts to body measurement. The Australian retailer Swimwear Galore breaks it down roughly as:

  • Baby boys (0–2) — secure fit is everything; look for snug leg openings, wide straps and zip fronts on sunsuits, in chlorine-resistant fabric.
  • Boys 3–7 — bright colours (neon orange, yellow) aid visibility in the water; easy-to-use fasteners help with independence. Briefs, trunks, jammers, rashies and board shorts all work.
  • Teen boys (8–16) — a secure, streamlined fit becomes the priority. Togs that sag, twist or ride up are a sign the fit is wrong; sizing here moves to chest and waist measurement rather than age.

The universal rule when a boy falls between sizes: size down slightly for a snug, safe fit. Swimwear stretches when wet, so a suit that is a touch loose dry will be noticeably loose in the water — and loose togs ride up, drag, and distract. Because sizing varies between brands, always check the individual product's size chart rather than assuming a "size 10" is identical everywhere.

Sun protection — the Australian priority

In Australia, no swimwear decision is complete without sun protection, and the standard here is strict. Cancer Council Australia explains that there are only four UPF ratings for clothing — UPF15, 30, 50 and 50+ — with UPF50 and 50+ (excellent protection, blocking around 98% of UV) recommended. A UPF rating reflects both the fabric's UV-blocking and the garment's coverage, so a rash top that covers the torso and three-quarters of the upper arms protects far more than board shorts alone.

For boys who burn easily or spend long days outdoors, the practical setup is board shorts or jammers plus a UPF50+ rash top, ideally long-sleeved. Cancer Council also notes that wet and stretched fabric loses some of its protection, so a well-fitting (not over-stretched) garment performs better — another reason to get the sizing right. The SunSmart approach pairs sun-protective togs with sunscreen, a hat and shade rather than relying on any one of them alone.

Fabric and care

The fabric decides how long boys togs survive a season of chlorine and salt. For boys who swim regularly, chlorine-resistant fabric (often polyester or a PBT blend) holds shape and colour far longer than standard nylon/elastane. Whatever the fabric, the care routine is the same and it pays off: rinse in cool fresh water straight after swimming, never leave wet togs balled up in a bag, dry in the shade, and keep them out of the hot wash and tumble dryer — heat is what kills the stretch. For boys who go through togs quickly anyway, a cheaper everyday pair plus one good chlorine-resistant pair for lessons is often the most economical split.

Board shorts or jammers: which to buy

The most common boys' togs question is board shorts versus jammers, and the honest answer is that most active boys end up needing both. Board shorts win for the beach, the backyard pool and holidays — they are casual, loose, quick-drying and the default for unstructured play. But they are poor for actual swimming: the loose fabric drags in the water and slows a child down, which is why they are rarely allowed for lessons or squad training. Jammers are the opposite — the knee-length compression fit is built for swimming, cuts drag, and survives daily chlorine, but they look out of place at a casual beach day.

The practical split for a school-age boy who both swims and plays is one pair of board shorts for the beach and one pair of jammers (or briefs) for lessons and training. For boys who only ever splash at the beach, board shorts alone are fine; for boys in a swim squad, jammers do the heavy lifting and board shorts are the extra. Buying for the wrong activity — board shorts for a swimmer, jammers for a beach kid — is the single most common boys' togs mistake.

Common fit mistakes

A handful of fit errors come up again and again. Buying too big "to grow into" backfires with swimwear: loose togs ride up and drag, and the child swims in something that never quite fits before it is outgrown anyway. Ignoring the waistband on board shorts leaves them slipping in the surf — look for an adjustable drawcord or elastic that actually holds. Skipping the rash top for a fair-skinned boy on a long beach day is the costliest mistake of all, given Australia's UV. And reusing last summer's togs without checking is worth a second look — stretched, faded fabric has lost both its fit and much of its sun protection, even if it still technically goes on.

Where to shop in Australia

Australian parents have strong options across price points:

  • Multi-brand surf retailers — City Beach stocks board shorts and beach togs across many brands under one roof, with regular sales; the City Beach sale guide covers the discount calendar.
  • Department and chain stores — Kmart, Target and Big W carry affordable everyday and school togs, ideal for fast-growing kids.
  • Specialist swim shops — for jammers, racing briefs and chlorine-resistant training togs from performance brands such as Speedo, Funky Trunks and Zoggs.
  • Sun-protection labels — including Cancer Council's own swimwear range, for UPF50+ rashies and sunsuits.

The short version: pick the style for the activity, size down for a snug fit, add UPF50+ coverage for the Australian sun, and choose chlorine-resistant fabric for anyone who swims often. Do that and a boy's togs will last the summer — and probably the one after.
