Aenergy TR 5 Womens

The Mammut Aenergy TR 5 Women is a light trail running vest and hydration carrier: 180 g, shaped for a woman's body, with two soft flasks included up front, a sleeve for a hydration bladder, a zipped back pocket and drop-in pockets for gels and bars. Sizes are XXS-XS, S-M and L-XL, in Black-Cloud.

Who it's for

Women who want water and fuel on them without the weight of a pack. Tempo runs on the Gold Coast hinterland trails, a long morning in the Glass House Mountains, a fast lap of the Blue Mountains tracks. Mammut rates it first for trail running, then mountain training, and it suits fast hikes too.

Capacity, and what actually fits

The two soft flasks come with the vest and ride in holders on the chest, where you can drink without breaking stride. For longer outings, a bladder slides into the hydration sleeve at the back and the tube runs over your shoulder. The zipped back pocket takes a wind shell, keys and phone, and the two drop-in pockets keep a gel or a bar in reach every few kilometres.

How it carries

The carrying system is shaped for a woman's body rather than scaled down from a men's vest. Wide, shaped shoulder straps spread the load, and adjusters at the chest and sides snug it down until it stops moving. There is a trekking pole carrier for stowing poles on the flats.

Fitting it

Each size is a range, so pick by the vest's own dimensions:

• XXS-XS: 37 cm tall, 25 cm wide
• S-M: 39.5 cm tall, 28 cm wide
• L-XL: 41.5 cm tall, 31 cm wide

If you sit between sizes, the adjusters give you room either way. Set the sides first with the flasks full, then fine-tune across the chest. Wear it over a running tee or a thin long-sleeve; it sits close, like a vest should.

Weight

180 g in every size, in a light, breathable 100% polyester build with open mesh across the chest, so it does not trap heat on a humid Queensland morning.
