Transition Backpack

Engineered to simplify the demands of triathlon preparation, the Transition Backpack features a structured three-section layout that separates wetsuits, clothing, accessories, and valuables for efficient packing before and after training or racing. A fully waterproof lower compartment isolates wet or used kit, helping to keep the main storage area clean and dry.

Durable polyester and PVC outer materials provide structural strength and weather resistance, while a PU-coated internal lining with sealed seams adds dependable protection from moisture. The generous 40L capacity is supported by a wide, stable base, allowing the bag to remain upright when packing or accessing compartments.

Breathable mesh padding on the back panel and shoulder straps enhances comfort during longer carries. Adjustable ergonomic straps help stabilise the load, while external mesh bottle holders, a protective smartphone pocket, and reflective detailing improve everyday usability across varied training environments.

Built for repeated use through training cycles, travel, and race weekends, the Transition Backpack delivers long-term durability and dependable organisation without unnecessary complexity.

Independently recognised by 220 Triathlon and consistently rated among the best transition packs available, it remains a trusted choice for athletes at every level. Available in both the new SS26 Teal/Sky colourway and the established Navy/Orange.

PURPOSE-BUILT ORGANISATION FOR SWIM–BIKE–RUN

The Transition Backpack’s tri-section layout gives wet kit, dry clothing, accessories, and valuables clearly defined storage zones. The result is faster packing, less clutter, and more confidence when preparing for training sessions or race days.

PROTECTED, WATERPROOF STORAGE

A fully waterproof lower compartment separates wetsuits or used kit from the rest of your equipment. Sealed seams and a PU-coated lining provide dependable protection, whether packing after in-the-water sessions or preparing kit ahead of competition.

COMFORTABLE, STABLE CARRY

Breathable mesh padding, ergonomic shoulder straps, and a supportive back panel create a stable carry system designed for varied loads. From daily training commutes to fully packed race-day use, comfort remains consistent.

DURABLE FOR REPEAT USE

Reinforced fabrics, secure compartments, and a stable 40L structure ensure reliable performance through regular training, travel, and race weekends. Both colourways offer identical durability and functionality.

Reviews

Excellent quality & comfortable to

"Excellent quality & comfortable to carry. Fits everything in. Would highly recommend this product."

— Noelle K. (5/5)

Good size bag

"Ideal transition bag with large main compartment and several smaller zipped pockets to keep items safe. Waterproof lower compartment is v handy post swim. So far only used it for outdoor swimming and not yet used it for an event - but it'll certainly hold all my kit. Added bonus is the fact it is within the dimensions for airline hand luggage so will be used for travelling too!"

— Liv M. (5/5)

Good size, rubbish zips.

"Bag size is great, compartment sizes are good sizes. However the zips are awful. They are extremely weak and break very easily. I thought it was a default on one bag but have had multiple replacements and they have all the same issue. Would not recommend."

— Becks (2/5)

Good transition bag

"I think the wetsuit compartment is a bit smaller. I would have preferred at least the opening larger. I need to squash and force the wetsuit in. The middle compartiment is really big. On the good side, it keeps your wet gear separated and it is large enough to fit a lot in."

— Dan S. (4/5)

This bag is amazing

"This bag is everything and more. Gone are the days of taking multiple kit bags to races. Everything fits perfectly in the transition backpack, and it has loads of smaller pockets for nutrition and all the smaller items needed for race day. I highly recommend this bag."

— Dylan W. (5/5)

Funktioneller Rucksack mit vielen Taschen

"Funktioneller Rucksack mit vielen Taschen um alles zu verstauen . Schönes Design . Größe des Rucksack ist ausreichend ."
