Amazon Essentials Boy’s Active Performance Stretch Knit Athletic Shorts
Product description
Overview: what these shorts are for
These amazon Essentials boys’ athletic shorts are built around one clear job: keeping things comfortable and flexible when the day is active. They’re a relaxed-fit style that sits at the waist and hangs with extra room through the hip, thigh and leg, which makes them a sensible pick if your child moves a lot (school sports, PE, playtime, weekend errands) and you want less fabric clinging or restricting.
On paper, the main appeal is the “classic feel with modern performance” approach. The fabric is described as mid-weight double-knit with a matte finish and an ultra-soft brushed interior. That should translate into warmth and comfort, plus stretch for ease of movement—useful during warm-ups, cool-downs, or those slightly chilly days when a lighter short alone feels too thin.
It’s not trying to be a hard-sport, high-compression training short. Instead, it leans more into an everyday activewear look with practical details, so it’s worth considering if you want comfort first and performance second.
Where the design helps in real life

The shorts include an elasticised waistband, plus a flat draw cord with a matte silicone-tipped end detail. That combination usually makes daily fit adjustments easier than relying on an elastic waistband alone, especially for growing kids.
You also get hand warmer pockets, which sounds like a small thing—until you’re dealing with boys who always want their hands in their pockets at the end of training. And at the hem, there are side vents for easier flexibility and movement. That venting can help when children are running, climbing, or just doing that constant shifting on the move.
The inseam is listed as 6 1/4” (15.9cm) on UK size 8 years, which gives you a decent baseline for how they’ll look and how much leg coverage you’re getting. If your child prefers longer shorts or looser coverage, you might still need to check sizing carefully rather than assuming everyone will feel the same.


Key features that matter (not just marketing)
The performance stretch knit is the headline here: a mid-weight double-knit fabric with a matte finish and a brushed interior. For many families, that “brushed” part is what decides whether something becomes a go-to for cooler mornings or lingering evenings.

The relaxed fit is also part of the practical equation. “Relaxed through the hip, thigh and leg” means it’s not cut to skim tightly, so it should suit kids who don’t like restrictive seams or who need room for movement and layering.
There’s also the simple, classic inspiration—tracksuit-style comfort, but in short form. That tends to work well as a casual training warm-up/cool-down option, or even as an “active day” alternative to joggers when the weather isn’t too cold.

Who it suits (and who should be cautious)

It’s a good fit if you want a relaxed, comfortable athletic short with stretch and a warmer interior, and you don’t need a very technical cut. You’ll likely like it if your child benefits from an elastic waistband they can wear comfortably all day, plus pockets for small essentials or just warm hands.


It makes sense if you’re looking for something that can bounce between PE and everyday wear—think after-school play where they’ll run around first and ask questions later.
However, it might not suit you if your child prefers a very sleek, tight training style, or if they dislike any “brushed” or warmer-feeling interiors when the weather is mild. It’s also worth remembering that the inseam is specified for a particular age size, so the length and how it sits could feel different across sizes.
Practical tips for getting the best fit
If you’re using this as an all-round PE short, check that the waistband sits where your child likes it (it’s designed to sit at the waist). If they tend to pull waistbands down or up, the flat draw cord with the silicone-tipped ends is there to help with adjustment.

A quick test at home helps: ask them to do a few stretches and a short burst of movement. The side vents at the hem are meant to support flexibility, but comfort still depends on how the relaxed fit lands around the hip and thigh for your child’s body shape.
Buying verdict
If you’re weighing up whether these boys’ active shorts are worth it, the answer is pretty straightforward: buy them if you want relaxed, stretchy comfort with a warmer interior for training sessions and cooler days, and you value pocket practicality.
Skip them if your priority is a lightweight summer training short, or if your child prefers a tighter, less relaxed fit. Since the fabric is described as mid-weight with an ultra-soft brushed interior, it may feel like more fabric than you need when the weather is warm.
