Brilliant Triathlon Bag

Excellent organisation of kit in one bag. Brilliant.

icon-circle-checkmark verified purchase

Not so much into triathlons rather road cycling and crit Racing. Needed a race day kit bag quick, and one that I could also sling on my back. For the price and convenience of same day pickup from local store via the stock checker it was a no brainer. Looks legit, feels legit and swallows, shoes, helmet, towel and food etc etc all with the bottom swim compartment zipped off. Buy it immediately!

Great transition bag

It's a straight forward functional transition bag. It's what you need from a bag for transition.

Muy practica

Muy practica y versátil

El producto me parece adecuado, dado que tiene la rigidez suficiente como para mantener los compartimentos separados sin necesidad de rellenar con ropa. El tamaño me parece casi ideal porque cabe de todo y se encuentra bastante bien separado. Si tuviera que buscarle algún inconveniente , decir que pega con lo qué la mayoría de estos productos pecan, de la cremallera, la cual acaba partiéndose tarde o temprano siempre.

Mochila perfecta

Todo guardado en su sitio

Muy incomoda mala distribución capacidad engañosa

Parecía muy buena y una vez probada muy incomoda, falta apartado exterior para bidón, y bolsillos exteriores para llaves o cosas que tengas que tener a mano, los interiores poco prácticos, llevo la grande de natación y mucho más cómoda y práctica.

Why is a transition bag useful?

As you know, the triathlon is made up of 3 different races: swimming, cycling and running! And for each sport, you'll need to change equipment. So, to help you organize your equipment, access it easily during the event and post-race recovery, we have created a bag with 3 different compartments (1 for each sport!) and various pockets. And for a stress-free race, we have even labeled each pocket and included a checklist of essential triathlon equipment!

Preparation, transport and the race: the 3 roles of the transition bag.

Before the race, your transition bag lets you organize all your triathlon equipment to make it easy to find. And thanks to its checklist, preparing your bag will quickly become part of your pre-race preparation. Its compact format lets you take all your equipment with you when you travel, and can even be used as cabin baggage when flying. During the race, its compartments will help you find your equipment more easily during your transitions without wasting time and without stress!

Our triathlon transition bag boasts compartments and a clever design:

As well as the separate compartment for each sport, here are more of the transition bag's handy features: - The swimming compartment can be removed from the rest of the bag. Its ventilated fabric means your suit will dry quickly. - The zipped pocket on the side of the bag, accessible with just one hand, lets you carry your doctor's certificate and other documents safely. - Its strap means you can hang up your bag. - Its adjustable shoulder straps are there for comfort before and after the race.

What size and for which sizes? more about our transition bag:

Triathlons come in different formats. With its 35 L size, your transition bag has been designed to help you take all the equipment you need for Super Sprint to Olympic races without having to stuff it to the brim. What about your size? You can easily fit a 5 mm XL or thin XXL neoprene suit and size 12 shoes in your bag!

The triathlon bag - a story of transition and different designs:

"Transitions are always the unknown in a triathlon". With this in mind, our team of 6 beginner and expert triathletes wanted to create a bag to help you manage these key moments as well as possible. 6 months of designing and consulting athletes from other sports, tests with 10 triathletes and 3 prototypes later, we are very proud to offer you a smart, practical and reassuring product that allows you to enjoy the very concept of triathlon, stress-free: the combination of 3 different sports.

Finally, a few words from our triathlete designers:

"The shape of the swimming pocket lets you put in your suit in a croissant shape: you don't want to damage the neoprene, so you should roll the suit up instead of folding it." "The biggest challenge was making the right choices to make sure that the bag wasn't too big and that each item could be easily organized inside. We came up with a bag that weighs 22 lbs when full. You'll look a bit like a Ninja Turtle, but you'll be surprised how much you can carry on your back!"
