Two toddlers in rain gear and boots walking across a wooden bridge on a forest trail

Gear Guide

What we actually bring to McCollum Park, tested by PNW toddlers.

Thinking about joining? Try a $15 class (opens in new tab) and see what Wednesdays are like.

New family? Here’s what you need for Wednesday.

What to wear

  • Rain suit
  • Rain boots
  • Base layers in merino or synthetic, no cotton
  • Warm hat and mittens on cold days

In the backpack

  • Full water bottle
  • Nut-free snack
  • Full change of clothes
  • Two clean washcloths in a ziplock bag, for muddy or painty hands
  • Diapers and wipes, or a pull-up and extra underwear if potty training
  • Sunscreen and bug spray in warmer months
  • Picnic or outdoor blanket

Potty training? Our privacy tent has a children’s potty, but I’d still pack a pull-up just in case. Accidents are no fun outside, especially on cold days. I’m always happy to talk through our setup and help make it work for your family.

We bring everything else: art supplies, sensory materials, hand lenses, and books.

What my daughter wears to Little Roots

On colder mornings, she wears both her iksplor and Reima base layers, and I add a fleece mid-layer and her Reima Paljakka beanie. Wind and shade make a big difference, so I go by how it feels outside, not a set temperature.

The Backpack

What to look for: A chest clip, a water bottle pocket on the outside, and light enough for your toddler to carry. We recommend 12L, or 18L for older or taller toddlers.

REI Co-op Tarn 12 L Pack (Kids) (opens in new tab)

Our top pick. Has a chest clip, water bottle pockets, and comes in fun colors. The 12L is the sweet spot for our 1 to 3 year olds who want to carry their own pack. It’s big enough for a change of clothes, snack, and water bottle without being too bulky for little shoulders. (If your child is on the older or taller side and wants more room to grow into, REI also makes an 18 L version.)

Tip:Label everything with your child’s name.

October through May

Sizing tip:Reima runs about one size big, so order your child’s current size.

One piece or two?Some forest preschools for older kids recommend rain bibs and a jacket over a one-piece, since they’re easier to get off for bathroom trips. At this age, though, one-pieces have real upsides. There’s no gap at the waist for rain, mud, or cold air to sneak in when they crouch, climb, and sit on the ground. Weigh what works best for your child and your family right now.

Layer 1: Base Layer

What to look for: Merino wool or synthetic, like polyester. OEKO-TEX certified is ideal. Long cuffs give them room to grow.

iksplor Merino Wool Base Layers (opens in new tab)

This is what my daughter wears under everything. Long limbs and thumbholes mean you get extra wear out of one size. They also make adult merino layers, so you can layer up the same way your little one does.

Reima Moomin Trivsam Base Layer Set (opens in new tab)

A toddler top and bottoms in a merino wool and lyocell blend. My daughter wears this on colder mornings along with her iksplor layers.

Layer 2: Fleece or Wool Mid-Layer (Colder Days)

What to look for: Fleece or wool, no cotton sweatshirts. Jackets that zip up the front are easiest for toddlers. Easy to find secondhand since kids grow out of them fast.

Patagonia Synchilla Fleece and Overalls (opens in new tab)

What my daughter and I both wear on cold mornings. My own Synchilla has made it through about ten years of fall and winter, so I don’t mind paying more for this one. My daughter wears an older version of the Baby Shearling Overalls (opens in new tab), soft recycled fleece with a center zip and elastic leg cuffs. Made in a Fair Trade Certified factory, and baby sizes start at newborn.

Reima Tahti Fleece Jumpsuit (opens in new tab)

If I were buying new, this is what I’d get. A one piece fleece that goes under the rain suit on cold mornings, with a full zip and a chin guard so the zipper doesn’t rub. Sizes run from 9 months to 3T. The same fleece also comes as a separate top and bottoms, the Tahto Knit Fleece Set (opens in new tab), which is a good pick if your child is potty training since the bottoms come off on their own.

Layer 3: Insulation (Coldest Days)

What to look for: Down or synthetic puffy jacket, snow pants or snow suit for the coldest stretches. If it’s not labeled waterproof, it goes under the rain layer. Check thrift stores for snow gear since kids outgrow it quickly.

OAKI Snow Suit (opens in new tab)

One piece means no gap between jacket and pants when kids are climbing and rolling around. It’s rated to 20°F below zero, and the grow-fit design buys you at least an extra season before sizing up.

Reima Toddler Winter Jackets (opens in new tab)

A good fit for layering, and they hold up well to repeated use.

Layer 4: Waterproof Outer Layer

What to look for: PU coated (not PVC) with sealed seams. Buy one size up so the other layers fit underneath.

OAKI One-Piece Rain Suit (opens in new tab)

A one-piece is fantastic for younger toddlers because there’s no gap at the waist for water to sneak in. Comes in tons of colors and is a forest school staple. (OAKI also makes separate rain jackets if you’d rather pair them with your own rain pants.)

Reima Lammikko Rain Bibs (opens in new tab)

Rain pants with suspenders and a high waist, so there’s no gap when they sit down in a puddle. They cover more than rain pants and are easier to get off than a one piece. Pair with any rain jacket.

OAKI Trail Rain Pants (opens in new tab)

What my daughter wears most days when it’s not raining. When she sits on wet ground or spills her water, she stays dry.

Therm Kids Rain Jacket (opens in new tab)

Made from 100% recycled fabrics. Their SplashMagic prints appear when the jacket gets wet, which is basically the coolest thing ever for a toddler in the rain.

Color tip:We recommend bright colors. They help your brain quickly scan for your child and spot them among the other kids and the forest.

Pro tip:Pull rain pants OVER the boots, not tucked in. Trust us on this one.

Mittens

What to look for: Waterproof, with cuffs big enough to go over the jacket sleeves.

Reima Reimatec Tepas Mittens (opens in new tab)

Waterproof and warm. A long zipper opens them wide so they’re easy to get on, and the long cuffs go over coat sleeves. Mittens are so much easier than gloves at this age: no coaxing tiny fingers into the right holes.

Reima Puro Rubber Rain Mittens (opens in new tab)

Fully waterproof rubber mittens with welded seams and a soft knit lining, for heavy rain and wet play. Sizes start at 6 to 18 months. They run big, so size down.

Reima Tumpus Fleece Mittens (opens in new tab) or Eino Merino Wool Mittens (opens in new tab)

Slim mittens for the stations. Bulky waterproof mittens make it hard to scoop, pour, or squish playdough, and a thinner pair lets little hands keep working without getting cold. Tumpus are soft, quick-drying fleece, and Eino are a light merino wool knit. Neither is waterproof on its own, so on wet days slip them under the Puro rain mittens. Sizes start at 6 months.

Hats

What to look for: Fleece or wool, with ties or a snug fit so it stays on.

Reima Paljakka Beanie (opens in new tab)

What my daughter wears on the coldest days. A merino wool blend with a fleece lining and ties to keep it on.

iksplor Merino Wool Beanie (opens in new tab)

A lighter, classic beanie. Slim enough to fit under a rain hood, and soft enough that toddlers actually leave it on. Sized from newborn through adult, so you can match.

Neck Warmers

Reima Neck Warmers (opens in new tab)

Reima has several neck warmer options, so you can pick the warmth and style that fits your child. A neck warmer is so much easier than a scarf for toddlers: it pulls right on, stays put, and has no loose ends to trip on or tug.

Wool Socks

Reima Parit Wool Socks (2 Pack) (opens in new tab)

A soft merino wool blend that fits snug inside rain boots on chilly days. My daughter wears these too.

June through September

Lightweight Base Layers

A lightweight merino base layer is one of the best things your kid can wear in summer. It breathes well as the morning warms up and gives some protection from the sun.

What to look for: Thin, lightweight merino wool. OEKO-TEX certified is ideal.

iksplor Lightweight Merino Base Layers (opens in new tab)

Their lightweight knit (around 150gsm) is our pick for summer.

Sun Hats

What to look for: A wide brim that covers the neck, UPF 50+, and a chin strap so it stays on.

Jan & Jul Cotton Floppy Sun Hat (opens in new tab)

Cotton, with sun protection that comes from the fabric itself and a chin strap to keep it on. You can buy a size up and tighten the drawstring, so it lasts more than one summer.

Trail Shoes

What to look for: Closed toes, good grip, and easy for toddlers to put on, like Velcro or pull tabs. No Crocs or flip flops on the trail.

Reima Tepastelu Toddler Waterproof Barefoot Shoes (opens in new tab)

These are what my daughter wears. They’re waterproof, with a wide toe box and a thin, flexible sole so they can feel the ground they’re walking on. The Velcro strap is easy for toddlers to do themselves.

Reima Lomalla Toddler Sandals (opens in new tab)

Lightweight closed-toe sandal for warmer days. Free of fluorocarbons and PVC. Good when they want something more open but you still want toe coverage on the trail.

Trail Socks

Wet cotton socks are how blisters happen. Look for wool or wool-blend socks that wick moisture and stay put inside shoes.

What to look for: Merino wool blend, no slipping inside shoes.

iksplor Natural Fiber Trail Socks (2 Pack) (opens in new tab)

Merino wool socks in kid and adult sizes. They actually stay up and dry fast when feet get wet.

Sunscreen

What to look for: A mineral sunscreen (zinc oxide) with no added fragrance, SPF 30 or higher. Put it on before you arrive. We can’t apply products to your child, but you’re welcome to reapply during class.

Babo Botanicals Sensitive Baby Mineral Sunscreen Lotion SPF 50 (opens in new tab)

This is what we use. It’s zinc only with no fragrance, and safe for babies 6 months and up. It also comes in a stick (opens in new tab).

Boots

What to look for: Natural rubber (not PVC), good grip, easy to pull on and off, wide enough for socks.

OAKI Kids Loop Rain Boots (opens in new tab)

Natural rubber, BPA-free, easy to pull on. They match the OAKI rain suits if you want a coordinated look. (OAKI also makes snow boots for the coldest months.)

PNW tip: McCollum Park mornings can be wet any month of the year. Keep a pair of boots in the car even on sunny days, or skip the trail shoes altogether and just make boots their default footwear for Wednesday.

Bug Spray

What to look for: No DEET, and safe for babies 6 months and up.

Badger Anti-Bug Shake & Spray (opens in new tab)

This is what we use. It’s made with plant oils like citronella and rosemary instead of DEET. It also comes as a balm stick (opens in new tab).

Baby Carriers

hope&plum Lark Baby Carrier (opens in new tab)

This is the one I use. It buckles on and carries on your front or back. The Baby Lark fits 10 to 45 pounds and the Kid Lark fits 25 to 65 pounds.

hope&plum Ring Sling (opens in new tab)

Quick to get on and off, which helps if your child goes up and down a lot between stations. Fits 7 to 35 pounds.

Water Bottles

What to look for: Stainless steel, with a lid your toddler can open.

Cold months tip:Fill a thermos-style bottle with warm water or warm milk. I recommend testing it at home a few times so they are used to it. Fill it warm, not hot, since insulated bottles keep drinks hot for hours.

Snack Containers

What to look for: Stainless steel or silicone, easy for toddlers to open on their own, and a lid that won’t spill in the backpack. Remember: all snacks must be nut-free.

Elk and Friends Stainless Steel Snack Cups (opens in new tab)

This is what we use. Stainless steel with a soft silicone lid toddlers can reach into, plus a travel lid that seals for the backpack.
