Size guide
Finding your fit
Our T-shirts, hoodies, polos and crewneck sweatshirts come in sizes S, M, L, XL and XXL. The easiest way to choose is to compare with something you already wear.
Measure a garment you like
- Lay a T-shirt or hoodie that fits you well flat on a table.
- Measure straight across the chest, from armpit to armpit.
- Measure the length from the highest point of the shoulder to the hem.
- Send us those measurements on WhatsApp or by message and we will suggest the closest GLUNS size.
Quick tips
- Between sizes? Go up one for a relaxed fit, especially for hoodies and sweatshirts you plan to layer.
- Polos for committee sessions: many delegates prefer their usual size for a neater look.
- Ordering for someone else? Check a garment from their wardrobe, or choose the Delegate Gift Box and tell us the size when you order.
Caps and beanies
The embroidered cap has an adjustable back strap. The knit beanie is one size with a fold-up cuff.
Still unsure?
Message us before you order. It is quicker to get the size right first than to arrange an exchange later.
