Gertrude — Size Guide

Introduction — How does Gertrude fit, in practice?

The Gertrude brand has established itself with puffer jackets and jackets featuring a technical, urban look, clean sweatshirts, and easy-to-wear t-shirts. Overall, the brand runs true to size:

• Jackets & puffer jackets: standard to slightly fitted → take your usual size.

• Sweatshirts & hoodies: a bit slimmer than average → if you are between two sizes, go for the size above for comfort.

• T-shirts: regular, true to size.

• Women: cuts are sometimes more fitted, but the FR sizing equivalence is consistent.

Measuring correctly (30 seconds to avoid a return)

• Chest: horizontal tape at the fullest point, breathing normally.

• Waist: at the natural crease, without tightening.

• Hips (W): at the widest point.

• Height: useful for judging the length of a parka.

Tip: if you are hesitating between two sizes, choose the larger one — especially for outerwear (mobility + durability).

Special cases — puffer jackets & quilted jackets

Gertrude puffer jackets are designed for a clean fit without restricting movement.

• Take your size if you wear the puffer over a thin sweatshirt.

• Add +1 if you often layer a thick hoodie or a chunky sweater.

• When trying on: zipped up, you should be able to fit 1–2 fingers between your torso and the puffer, and cross your arms without pulling at the shoulder blades.

Visual tip: add modeled photos (profile + front + back) for each style with the model's size in the caption (e.g., 5'10" • M), it reassures customers and reduces returns.

Choose quickly (need → piece → size)

Try at home: the anti-return checklist

• Put on your thickest layer (sweater/hoodie) before trying it on.

• Cross your arms: there should be no discomfort in the shoulders/shoulder blades.

• Zip closed: 1–2 fingers of ease at the chest.

• Length: short = mobility, mid-thigh (parka) = protection.

• Between sizes: choose the larger one.

Care (to maintain shape & loft)

• Down jackets / vests: 30°C delicate, gentle detergent (ideally down-specific if indicated), long rinse, light spin. Dry on low heat with 2–3 dryer balls to restore loft, or lay flat while periodically kneading the baffles.

• Technical jackets / softshells: 30°C, no fabric softener (it ruins water repellency), air dry.

• Sweatshirts & t-shirts: 30°C inside out, gentle spin, dry flat to prevent misshaping.

FAQ — Gertrude sizing

Does Gertrude run large?
It's pretty standard. Sweatshirts/hoodies fit a bit slimmer: if you're unsure, go one size up.

I often wear hoodies, what should I do for the down jacket?
Take your size if the hoodie is thin; go +1 if you regularly wear thick knits.

Are "Bright" styles more fitted?
They often have a clean finish. Stick to TTS; +1 if you want ease or a slightly oversized look.

Is the César vest warm?
Yes, on the torso. It is designed for layering (over a sweatshirt / under a parka).

I am between M and L: how do I decide?
For down/softshell, take L (ease + mobility). For t-shirts, M if you want a clean look.
