Backpack 'Explorer' - Grey

Explorer – 45L Grey Gym Backpack With Shoe Space for Training and Travel

The Explorer in grey by Gym Generation is a gym backpack with 45 litres of volume, built to the standard of tactical gear and made for the gym, training and travel. The muted grey is the modern, softer answer to black – understated, matter-of-fact and easy to pair with anything. Rugged 900D nylon oxford, a modular laser-cut MOLLE system and a supportive carry harness come from the same world, and inside everything has its place: the large main compartment opens like a suitcase and takes a full training kit or a week of luggage, the middle compartment holds your shoes, a padded back sleeve protects your laptop, and two side pockets hold a bottle or shaker up to 1000 ml. Measurements 48 × 34 × 29 cm, carry-on size. The Explorer is part of the gym backpack range from Gym Generation and comes with a velcro patch panel and two patches included.

Grey – Softer Than Black, Quieter Than Colour

Grey is for anyone who finds black too hard and colour too much. The muted tone reads matter-of-fact and modern – a shade lighter and more urban than black, and just as simple to wear with anything. It is the quiet option that never asks for attention and works in any room, from the gym floor to the office. Against the grey, the black patch panel with the Spartan logo cuts a clean line. Understated, not dull. Gym Generation has been a Swiss gymwear brand since 2013. Shipped from Switzerland.

Built to Tactical Standards

What separates the Explorer from an ordinary workout backpack is how it is built. The material, the MOLLE system and the carry harness all come from a world where gear takes heavy loads and hard use for years. The 900D nylon oxford is dense, abrasion-resistant and bar-tacked at the stress points. Inside sits a coated lining you can wipe out – not a fashion product that wears through after one season, but a pack that stays with you as long as you train.

Enough Compartments, Each With a Job

The middle compartment takes your shoes, away from the fresh change of clothes. The large main compartment opens like a suitcase – you pack flat and see everything at a glance – and carries a mesh organiser with a zip pocket inside. At the front sits a compartment with an organiser panel for cables, charger and small items. So after a workout you are not reaching between trainers for the shaker.

Padded Laptop Sleeve at the Back

The back holds its own padded sleeve for a laptop or documents, secured with a velcro tab and shielded by the back padding. Your device rides against your spine, separate from the rest of your luggage. Passport and valuables sit hidden and safe here.

A Week as Carry-On – Including the Away Competition

At 48 × 34 × 29 cm the Explorer sits within the carry-on format of most airlines, and 45 litres covers a whole week. For a competition you have to fly to: shoes, clothes, food and laptop in one pack, no waiting at the belt, no checked-bag fee. Off the plane and straight to the venue. Do one trip on hand luggage alone and you will not want to go back.

Laser-Cut MOLLE and Carry Harness

The front and sides carry a laser-cut MOLLE system: rows of loops cut straight into the fabric for pouches, carabiners or accessories, flatter and cleaner than stitched webbing. The carry harness behind it is built for a full load: thickly padded S-curve straps, a chest strap, a hip belt to shift the weight and load-lifter straps that pull the pack in against your back. The ventilated mesh back panel cuts down on sweat. You carry it by the shoulder straps, the top handle or the two reinforced D-ring loops, and two rows of compression straps pull the pack down to day-trip size.

Your Patch Panel, Your Statement

A full velcro panel in black sits on the front, and this is exactly where the Explorer becomes yours. Two patches are included: the Spartan logo and the Gym Generation lettering, both of which read clearly against the dark panel. Swap them, combine them or add more – our patch collection gets new designs all the time.

Explorer Backpack – Frequently Asked Questions

What is the difference between grey and black?
Both are understated and go with everything. Grey reads a shade softer and more modern; black is stricter and more classic. If you want the most anonymous option, take black; if you want something a little more urban and a little lighter, grey is the one. A matter of taste – both work anywhere.

What makes the Explorer better built than other gym backpacks?
900D nylon oxford fabric, a laser-cut MOLLE system cut straight into the fabric and a carry harness with hip and load-lifter straps – components designed for heavy loads and years of use rather than for a season.

Can I stow my shoes in the Explorer?
Yes. The middle main compartment holds them, separate from the fresh clothes in the large compartment, and the coated lining wipes clean afterwards.

How much fits in the Explorer?
The 45 litres take a complete training kit including shoes, towel and shaker – or the luggage for a week of travel.

What is the difference between the Explorer and the Adventurer?
Same build, same material, same volume – the difference is the look. The Explorer runs modern laser-cut MOLLE and a full velcro patch panel: cleaner, with more room for patches. The Adventurer carries classic stitched MOLLE webbing and narrow velcro strips: the original, raw tactical look. The choice comes down to taste.

Does the Explorer work as hand luggage?
Yes. At 48 × 34 × 29 cm it sits within the usual hand luggage rules of many airlines, and there is room for clothes, shoes and food for several days. Since every airline sets its own dimensions, it is worth a quick look at theirs beforehand.

Does a laptop fit in the backpack?
Yes. The back holds a padded sleeve with a velcro closure for standard 15 to 16 inch laptops, sitting against your spine and separate from the main compartment.

Is the Explorer comfortable to carry fully loaded?
That is what the carry harness is built for. Padded S-curve shoulder straps, a hip belt to shift the load and load-lifter straps keep the weight close to the body. Fully packed, the load spreads noticeably better than on a training backpack without a hip belt and load system.

Can I attach my own patches?
Yes. Any patch with a velcro backing fits the panel. Two Gym Generation patches are included, and you will find more in the patch collection in the shop.
