Find your size
Measure yourself, then read across. If your waist and hip point at different sizes, go with the hip — the ribbed waistband covers a range, the seat does not.

| XXS | 24–25" | 34–35" |
| XS | 25–26½" | 35–36½" |

Description
Description
A 100% pure Himalayan cashmere pair of joggers, hand-combed from Chyangra (Changthangi) goats and knitted by artisans in Nepal — NPIA-certified for authenticity. Loungewear that feels considered, never casual.
Effortless Style. Vibrant Luxury.
The Zenith Sweatpant redefines the casual staple. Designed for the individual who refuses to compromise on style or comfort, these trousers offer a refined, straight-leg silhouette that instantly elevates an off-duty wardrobe. It is the definitive piece for a life of "Quiet Luxury."
Fluid Architecture
Designed with a relaxed straight-leg cut, the Zenith offers fluid movement and a sophisticated, elongating drape. Unlike traditional, cuffed joggers, these trousers provide a structured aesthetic that transitions seamlessly from a first-class cabin to a home office. The open hem allows the pure cashmere to flow naturally with your stride, creating a look that is as authoritative as it is comfortable.
Saturated Sophistication
While our natural collection celebrates the earth, this series celebrates the vibrancy of personal style. Utilizing a premium dyeing process that preserves the integrity of the 16-micron fibers, we have created a palette of deep, saturated colors. These hues add a layer of sophistication to your daily ritual, ensuring your loungewear looks as polished as a tailored suit while feeling like a "second skin."
Why the Zenith is a Wardrobe Hero:
- Vibrant 2-Ply Resilience: Two strands of premium yarn are twisted together for enhanced strength and superior shape retention. They "bounce back" after wear, resisting the knee-sagging common in lesser knits.
- The Ultimate Travel Trouser: A naturally warm layer that keeps you cozy in chilly cabins, from departure to arrival.
- Artisanal Integrity: Individually hand-finished by master artisans in Nepal, carrying a level of soul and durability that mass-produced knitwear cannot match.
- NPIA Certified Purity: 100% pure Himalayan cashmere. Ethical luxury in its most vibrant form.

Cashmere is a fine animal hair, not a hard-wearing wool. It responds to cool water and gentle handling, and almost all damage comes from heat and agitation rather than from wearing it. Treated properly, a piece lasts years rather than seasons.

How do I wash cashmere?
By hand is best. Fill a basin with cool water — no warmer than about 30°C / 86°F — and add a capful of a mild wool or cashmere detergent. Submerge the piece and press it gently under the water for two or three minutes. Do not rub, wring or twist. Rinse in cool water of the same temperature until the water runs clear.
By machine, only if the cycle is genuinely gentle. A wool or delicate cycle works if it stays cool and spins slowly. Turn the piece inside out, put it in a mesh laundry bag, and use a low or no spin setting.
The one thing to avoid is thermal shock. Hot water, a sudden change in temperature, or vigorous agitation causes the fibres to lock together permanently. That is felting, and it cannot be reversed. For the same reason, skip bleach, fabric softener and the tumble dryer.
How do I dry cashmere?
Press the water out between two towels rather than wringing. Reshape the piece while it is damp, then lay it flat on a dry towel away from radiators, direct heat and strong sunlight. Never hang a wet knit — the weight of the water pulls the shoulders and body out of shape as it dries.
Why is my cashmere pilling, and how do I fix it?
Pilling is friction, not a fault or a sign of poor quality. It appears wherever the garment rubs against something — under the arms, along a seatbelt, where a bag strap sits. It is most noticeable in the first few wears and settles down after that.
Lay the piece flat and remove pills with a cashmere comb, working lightly in one direction and letting the comb do the work. Do not pull them off by hand, which drags the surrounding fibres.
Avoid battery fabric shavers. They cut into the surface and thin the knit over time. A comb lifts the pills off; a shaver removes fibre you cannot put back.
How should I store cashmere?
Never hang it — hanging stretches the shoulders over time. Whether you fold or roll depends on how the piece is made.
- Knitwear — fold. Sweaters, cardigans, hoodies, joggers and polos. Fold along the existing seams and stack loosely.
- Woven pieces — roll. Shawls, wraps, ponchos and capes. A fold leaves a permanent crease along the fold line, so roll them loosely instead, with acid-free tissue if you have it.
- Beanies, headbands, socks and gloves — store flat. They keep their shape far better flat than stuffed into a pocket or a drawer corner.
Always store it clean. Moths are drawn to skin oils, perspiration and food traces rather than to the fibre itself, so a piece put away unwashed is far more vulnerable than a clean one. Use a breathable cotton bag with cedar or lavender, and avoid airtight plastic, which traps moisture.
Do I need to wash it after every wear?
No, and you shouldn't. Cashmere benefits from resting between wears — give it a day to recover its shape. Airing it usually does more than washing, and a small mark is better spot-cleaned than put through a full wash.
Is dry cleaning safe?
Yes, and it is a good option for structured pieces or stubborn marks. Choose a cleaner who handles cashmere regularly. Most pieces do not need it often; hand washing at home is gentler and perfectly adequate for routine care.
Care for shawls and wraps
Handwoven shawls are finer than knitwear and prefer hand washing. Do not iron directly on the fabric — if a piece needs pressing, use a cool iron under a cloth, or hang it in a steamy bathroom and let the creases drop out. Fringes can be combed straight with your fingers while damp.

Good Enough
The Heather Gray Zenith Sweatpant is my most-worn bottom of the year. The 350g pure Himalayan cashmere is warm enough for cooler days and thermoregulating enough for warmer ones, and the heather gray colour pairs with everything I own. The 2-ply 16 micron construction is beautifully fine. Exceptional.
The pure Himalayan cashmere quality in the Zenith Sweatpant is genuinely impressive — fine, soft, and beautifully draped. My significant disappointment is colour: the Pine arrived much more blue-toned and less rich than the deep forest green shown in the listing. For a premium product at this price colour accuracy matters.
Honestly didn't expect much — absolutely blown away.
The Off-White Zenith Sweatpant is what I recommend to anyone wanting cashmere loungewear that's also appropriate beyond the home. The 350g pure Himalayan cashmere is extraordinarily soft and the off-white colour is elegant and clean. NPIA certified. Outstanding.
