Quick answer

If you want one safe order, size the TRIBE Classic Mountain Hoodie true to your usual unisex size, take the Share The Adventure T-Shirt true to size in a relaxed unisex cut, and buy socks by the job rather than by habit: the TRIBE Crew Socks 3 Pack for everyday wear and the TRIBE x SUMS Run Socks for running. The hoodie is the only piece where the size list and gender option both matter, so decide your fit first and your size second.

What the size options actually tell you

Two of the four merch pieces are sized by Size alone: the TRIBE x SUMS Run Socks and the TRIBE Share The Adventure T-Shirt. The TRIBE Crew Socks 3 Pack is instead listed by Title, which means you are choosing a colourway and pack variant rather than a body size — one less decision to get wrong. The TRIBE Classic Mountain Hoodie is the only item with both Size and Gender options, so you pick a size and a fit direction together.

That difference matters at checkout. For socks and tees you can order the same size you always wear and expect a predictable result. For the hoodie, the gender option is doing real work, and ignoring it is the most common way people end up with a fit they did not intend.

How to read the hoodie's dual size and gender options

The Classic Mountain Hoodie is described as unisex and made from a super soft material. The catalog shows two reference fits: Harriet wears a Female Size M and Tom wears a Male Size L. Use those as your anchor points rather than guessing. If you normally wear a women's medium, Harriet's fit is the closest match; if you normally wear a men's large, Tom's is.

If you sit between the two — for example, you usually buy a women's large or a men's medium — decide what you want the hoodie to do. A closer fit for layering under a jacket points you to the smaller of your two options. A looser, throw-it-on fit points you to the larger. There is no published chest measurement in the catalog, so if you are between sizes and need an exact number, treat that as a genuine limitation and size up rather than down for a relaxed result.

T-shirt fit: what the fabric tells you

The TRIBE Share The Adventure T-Shirt is a premium heavyweight organic unisex cotton tee with a print on the back. Heavyweight cotton holds its shape better than thin jersey, but it also has less give, so the tee will not stretch to cover a size gap the way a lighter fabric might. Order your normal unisex size and expect it to sit close to true.

Because the graphic sits on the back, the tee reads as a statement piece from behind and plain from the front. If you plan to wear it layered under an open hoodie, the back print will mostly be hidden — in that case treat it as a base layer and prioritise fit over the graphic.

TRIBE crew socks vs run socks: pick by the job

These two sock products are not interchangeable, and the names tell you why. The TRIBE Crew Socks 3 Pack is built around everyday comfort: friction-free performance fabric that won't pill, compression zones for stability and fit, and a fully custom-knitted design in White and Blue. That makes them the pair for the gym floor, the commute and daily wear, where durability and looks matter more than race-day detail.

The TRIBE x SUMS Run Socks are a limited-edition collaboration built for all year round, with light compression, anti-blister cushioning, breathable mesh and a zero-slip arch band. Those features target the specific problems of running — heat, friction and movement inside the shoe. If you run regularly, the run socks are the pair that earns their place; if you just want good socks for everything else, the 3 pack covers you three times over.

Care rules that protect the fit you paid for

The crew socks are explicitly designed with fabric that won't pill, but that property still depends on how you wash them. Turn them inside out, wash cool, and skip the tumble dryer — heat is what degrades compression zones and arch bands over time. The same logic applies to the run socks: the zero-slip arch band and light compression only work while the elastic is intact.

For the heavyweight cotton tee and the super soft hoodie, wash cool and dry flat or on a low setting to limit shrinkage and print cracking. Keep the back print on the tee away from direct iron contact. If you own several TRIBE pieces, wash them together on a cool cycle so you are not running separate loads for a hoodie, a tee and a few pairs of socks.

Decision rules for ordering TRIBE merch

  • If you are between hoodie sizes: Match yourself to the closest published fit first — Harriet in Female Size M or Tom in Male Size L — then size up for a relaxed layer and stay true for a closer fit. No chest measurements are published, so when in doubt, size up rather than down.
  • If you want one tee that works everywhere: Order the Share The Adventure T-Shirt in your normal unisex size; heavyweight cotton will not stretch to hide a size gap. True to size is the safe call.
  • If you are choosing between the two sock products: Pick the Crew Socks 3 Pack for daily wear and the TRIBE x SUMS Run Socks for running, where the anti-blister cushioning and zero-slip arch band matter. Buy by job, not by price per pair.
  • If you are buying more than one piece: Lock in the hoodie fit first, since it is the only item with both size and gender options, then add the tee and socks in your usual sizes. One decision drives the whole order.

Product facts

  • TRIBE Classic Mountain Hoodie: TRIBE Unisex Classic Mountain Hoodies are made from a super soft material and come with new TRIBE mountain branding; Harriet wears a Female Size M and Tom wears a Male Size L. The two named fits are the only concrete sizing anchors published for this hoodie, so match yourself to Harriet or Tom before choosing your gender and size options.
  • TRIBE Share The Adventure T-Shirt: Premium heavyweight organic unisex cotton tee with the Share The Adventure print on the back. Heavyweight cotton holds shape but has little stretch, so order your normal unisex size rather than sizing down for a tighter look.
  • TRIBE Crew Socks 3 Pack: Friction-free performance fabric that won't pill, compression zones for stability and fit, and a fully custom-knitted design in White and Blue colourways. These are the everyday, all-rounder socks — buy them by the pack for general wear rather than as a running-specific pair.
  • TRIBE x SUMS Run Socks: Limited Edition collaboration with SUMS running socks, built for all year round, with light compression, anti-blister cushioning, breathable mesh and zero-slip arch band support. The cushioning, mesh and arch band are running-specific features, so choose these over the crew pack when the sock's job is time on your feet in shoes.

Who this merch sizing approach suits

Best for

  • Runners who want one pair of socks for training and one pack for everyday wear
  • Anyone layering a heavyweight tee under a hoodie and needing both to fit together

Not for

  • Shoppers who need exact chest or foot measurements before buying, since the catalog does not publish them
  • Buyers looking for a running-specific sock in the crew 3 pack, which is built for everyday wear
