Urban exploration
Some outings take you across changing terrain every ten minutes: an uphill trail, a climbing move to get over a rocky outcrop, then a sunlit traverse. RIOUPOU was designed for days like these, when you don’t want to think about your pants.
The knit fabric, made from recycled ECONYL polyamide and Lycra elastane, stretches in all four directions, letting you take a long stride, raise your heel high, or lift your knee without the leg pulling. The 175 g/m² fabric stays lightweight and breathable as the temperature rises, and the pants weigh just 282 g.
Two hand pockets and a front patch pocket, all with zippers, keep your phone, snack bar, and keys secure even when you bend down or climb. The belt loops accommodate a slim belt to fine-tune the fit under a climbing harness or backpack.

PERFORMANCES
RIOUPOU blocks ultraviolet rays with a UPF50+ rating, the highest level on the textile protection scale. Important point: this protection comes from the density of the knit itself, not from an additive applied during finishing. So it doesn’t wear off over time with washing, unlike a chemical treatment that fades. On a full-sun traverse, an exposed approach to a climbing route, or a ridge walk above the tree line, your thighs and calves stay covered without you having to think about it.
This UV protection doesn’t come at the cost of extra warmth. The 175 g/m² knit stays lightweight and breathable, letting sweat escape during exertion, for a full-length pair of pants weighing 282 g.
RIOUPOU fabric stretches in all four directions, both widthwise and lengthwise. In practice, a high climbing step, a split to step over a boulder, or a high heel raise meets no resistance from the fabric, and nothing rides up above the shoe. Lycra elastane ensures it holds its shape, outing after outing.
Both hand pockets and the front patch pocket are zippered. It’s a detail you appreciate as soon as you find yourself on all fours on a slab or sitting at a belay: nothing slips out. The belt loops also keep the pants in place, even under a tight harness.
Did you know? The ptarmigan, our totem animal, changes its plumage with the seasons: white in winter to blend into the snow, it fluffs up its feathers to protect itself from the cold and smooths them down again when temperatures rise. It constantly adapts, never wearing more than it needs.
RIOUPOU follows the same principle. It acts as a base layer, worn directly against the skin, designed to wick away sweat while remaining comfortable against the skin. On cool or windy days, you can wear waterproof overtrousers on top without discomfort or chafing, thanks to its close fit and fine-knit fabric. On a warm day, it works on its own.
Fit & support
RIOUPOU has an Active Fit cut, a men’s close-fitting style that follows the leg without compressing it. The idea is simple: no loose fabric to catch on rocks or twist in gaiters, but enough freedom to lift your knee over a ledge or keep walking for hours.
The belt loops let you add a strap and adjust the fit depending on what you wear underneath and whether you’re carrying a backpack or wearing a harness. Lycra elastane does the rest: the trousers return to shape after every movement and don’t stretch out at the knees by the end of the day. They can be worn directly against the skin as a base layer on your lower body, with a thin pair of tights underneath when temperatures drop.
Coupe Active Fit
Coupe ajustée à la taille et aux cuisses, plus dégagée au niveau du genou pour ne jamais freiner le geste technique. Le bas de jambe reste étroit pour rentrer facilement dans une chaussure de randonnée ou de ski. L'équilibre entre maintien et liberté de mouvement.
SIZE GUIDE
Make your equipment last
Laver en machine à 30°C avec une lessive douce, éco de préférence, et sans excès.
Pas de javel : ni les fibres ni les couleurs n'y survivent, mieux vaut s'abstenir.
Ne pas nettoyer à sec : les solvants du pressing ne lui réussissent pas.
Fermer zips et boutons avant lavage, pour protéger la pièce et le reste de la machine.
Laver avec des couleurs similaires, pour éviter les mauvaises surprises au déballage.
Éviter le sèche-linge : mieux vaut la sécher à l'air libre, sur un cintre de préférence.
Ne pas repasser : cette matière n'apprécie pas du tout la chaleur du fer.
