Smelling good while on the go is made easy with one of these sleek, handy roll-on fragrances.

Diptyque's Eau Moheli Roll-on Cologne (HK$480/20ml) evokes a heady, exotic sensation with a core of ylang-ylang essence and ambrette seeds. Complementing the ylang-ylang flower's spiciness are pink peppercorn and ginger CO 2 in the top note, along with tropical scents from patchouli essence and vetiver.

Jill Stuart's Vanilla Lust Eau de Parfum Roll-on (HK$230/10ml) is one of three newly launched scents from the New York brand - the other two being Night Jewel (crystal, fruity, floral) and Jill by Jill Stuart (sensual, floral bouquet). Its creamy top note of praline, caramel and coconut is followed by a sweet, floral core of jasmine petal, freesia blossom, tiare, orange flower, peach and raspberry. Sandalwood, pure vanilla and musk make up the base. For a little added elegance, the cap is adorned with a Swarovski crystal.

Jurlique's Essence of Rose Roll-on Fragrance Oil (HK$220/11ml) not only has a feminine, floral scent, but is also said to be calming and good for the skin. An all-natural and alcohol-free fragrance oil, its signature scent and nourishing properties come from a blend of rose oils, extracts of the brand's own organically grown rosa gallica and shea butter.

Victoria's Secret's Victoria Eau de Parfum rollerball (HK$178/50ml) seeks to echo the flirty and chic image of the lingerie brand. The bottle is adorned with a pink metallic bow and encases a sweet scent of red berries, Victoria rose and crème brûlée. The collection also features a full-size eau de parfum, body lotion and body mist to ensure your scent lasts all day.
